I-titanium-nickel alloy round bar kanye ne-titanium-nickel alloy wire yizinto ezimbili ezingamasemi-finished forms abaluleke kakhulu ku-Nitinol, okuyinto ecishe ilingane ne-equiatomic nickel-titanium material ehlanganisa ukuziphatha kwe-shape memory kanye ne-superelasticity yangempela. Isidingo se-Nitinol round bar kanye ne-Nitinol wire siyaqhubeka sikhula ngoba onjiniyela kuma-medical devices, i-aerospace, i-oyili negesi, i-automotive kanye ne-general industry badinga insimbi ekwazi ukubuyisela ama-strains amakhulu, ukumelana nokukhathala kanye nokuhlala i-biocompatible ngesikhathi esisodwa. I-Baoji Dong Intec Metal Materials Co., Ltd., esebenza isuka e-Baoji esifundazweni sase-Shaanxi, yakhe ibhizinisi layo ekuguquleni izinsimbi eziyivelakancane zibe amashubhu, ama-bar, i-wire, ama-plate, i-foil, i-mesh, ama-disc, ama-ring kanye nemikhiqizo ye-alloy eqediwe, futhi lokhu kufaka phakathi i-titanium-nickel alloy round bar kanye ne-titanium-nickel alloy wire. Ngenxa yokuthi inkampani ihlezi ngaphakathi kwe-industrial ecosystem eyaziwa ngokuthi i-China's Titanium City, ingasebenzisa amandla avuthiwe endawo okuncibilikisa, okufaka kanye nokuqedela kunokuthi ihlanganise i-supply chain isuka ekuqaleni. Inkampani inesikhundla esihlangene ekucubunguleni izinsimbi eziyivelakancane futhi iphinde ikhiqize ama-titanium springs kanye ne-custom alloy hardware, okuqinisa ukuqonda kwayo ukuthi i-Nitinol iziphatha kanjani ngemuva kwe-cold working kanye ne-heat treatment. Lesi sikhombisi-ndlela, ngakho-ke, sihlanganisa izisekelo ze-Nitinol, izakhiwo zayo, umqondo we-specification ngemuva kwe-round bar kanye ne-wire, ukukhiqiza kanye nokulawulwa kwekhwalithi, izimo zemakethe, kanye nemibandela esebenzayo yokukhetha umhlinzeki e-China. Abafundi abafuna ukubona uhla lwemikhiqizo olubanzi bangavakashela i-IKHASI LASEKHAYA ikhasi lokuthola umbono wamakhono enkampani.

I-titanium-nickel alloy iyinhlanganisela ye-intermetallic, hhayi i-alloy evamile ye-solid-solution, futhi ukuziphatha kwayo kobunjiniyela okusebenzisekayo kubonakala lapho i-nickel ne-titanium zihlala eduze kwesilinganiso se-athomu esisodwa kuya kwesinye. Empeleni, amazinga okuhweba asuka cishe ku-54.5 kuya ku-57.0 amaphesenti ngesisindo e-nickel, kanti okusele yi-titanium kanye nezakhi ezisele ezilawulwa ngokuqinile njenge-oxygen, i-carbon, i-iron ne-hydrogen. Le nto yaziwa ngamagama amaningi — i-Nitinol, i-TiNi, i-NiTi, i-nickel-titanium, futhi ezincwadini zolimi lwesiShayina njenge-钛镍合金圆棒 kanye ne-钛镍合金丝 — nakuba wonke la magama achaza umndeni ofanayo wokwakheka okucishe kulingane. Abakhiqizi bahambisa i-Nitinol nge-round bar, i-wire, i-tube, i-plate, i-strip, i-ribbon ne-sheet, futhi ukukhethwa kwesimo kunquma ukuthi iyiphi indlela ye-thermo-mechanical okufanele i-mill iyisebenzise. I-Nitinol ihlinzekwa ngezigaba ezimbili ezibanzi zokuhweba: izinga lezokwelapha, elilawulwa amazinga afana ne-ASTM F2063, kanye nezinga lezimboni, elilandela imidwebo yamakhasimende kanye nezicaciso zangaphakathi esikhundleni semibhalo ye-implant-grade. Ukuphathwa kwekhwalithi jikelele, okwamanje, ngokuvamile kuqinisekiswa nge-ISO 9001, kanti isitokwe se-titanium implant esihambisana nezinhlelo ze-Nitinol sivame ukuqinisekiswa nge-ASTM F136.

Isizathu sokuthi umndeni owodwa wengxubevange uhlukaniseke ube amagredi amaningi kangaka ukuthi ingxenye yeshumi yephesenti lenikeli, noma amakhulu ambalwa ezingxenye ngemiliyoni zomoya-mpilo, kushintsha izinga lokuphela kwe-austenite ngendlela ebonakalayo. Lokho kuzwela kwesimo kusho ukuthi indunduma eyindilinga ye-Nitinol eyodwa eyayiodelwa ukusetshenziswa kwe-superelastic guidewire kanye nendunduma ye-Nitinol eyayiodelwa i-actuator eshukunyiswa ngokushisa kungase kwabelane ngamakhemikhali afanayo kodwa kufanele icutshungulwe ngendlela ehluke ngokuphelele. Abathengi abathatha i-Nitinol njengensimbi engagqwali evamile — becacisa kuphela ububanzi kanye nokubekezelela — ngokuvamile bathola igebe esigabeni sokuhlola, lapho amazinga okuguqulwa noma impilo yokukhathala ewela ngaphandle kwalokho obekulindelekile. Ngakho-ke abahlinzeki abahle bacaphuna indunduma eyindilinga kanye nocingo ngokwakheka, izinga lokuguqulwa, isimo kanye nokuqedwa kwendawo kukhonjiswa ndawonye, hhayi njengezinto ezihlukene zomugqa. Yingakho futhi abathengi abanolwazi bacela iqoqo lokushisa eliqinisekisiwe esikhundleni sombhalo ojwayelekile othi "NiTi".

Isici esichazayo se-titanium-nickel alloy round bar kanye ne-titanium-nickel alloy wire ukuhlanganiswa kwe-shape memory effect kanye ne-superelasticity ezintweni ezifanayo. I-shape memory isho ukuthi ingxenye ekhubazekile ngaphansi kwezinga lokushisa layo lokuguqulwa ibuyela esimweni esikhunjulwayo lapho ishisiswa ngaphezu kwalo, okuyisisekelo sama-thermally activated couplings, ama-actuators kanye nezinqubo zokukhulula. I-superelasticity, ngokuphambene, ivumela i-alloy efanayo ukuthi ibuyisele ukukhathazeka okulinganiselwa kumaphesenti ayisithupha kuya kwayisishiyagalombili emazingeni okushisa omzimba noma asendaweni ngokusebenzisa i-stress-induced martensite, ikhono okungekho insimbi engagqwali noma i-cobalt-based alloy engalinanela. Amandla okudonsa ku-cold-drawn Nitinol wire angadlula ku-1,000 kuya ku-1,500 megapascals, futhi into esetshenzwe kahle ibekezelela izigidi ezingamashumi okujikeleza kokukhathala ngaphansi kwe-strain amplitude efanele. I-Nitinol futhi imelana kakhulu nokugqwala, ayinazibuthe ngokuyisisekelo, futhi inokuncipha okungajwayelekile kwe-mechanical damping kanye nokuncika okunamandla kwezinga lokushisa ku-modulus yayo.

Uma kuqhathaniswa nensimbi engagqwali, izingxube zethithani ezifana ne-Ti-6Al-4V, nezingxube ze-cobalt-chromium, i-Nitinol ishintshanisa ukuqina kanye nokusebenzeka kalula ukuze ithole ukunwebeka okubuyiselayo okungenakuqhathaniswa kanye nokuhambisana nomzimba. Insimbi engagqwali ishibhile futhi kulula ukuyishisela, i-Ti-6Al-4V inamandla aqondile amahle kakhulu, kanti i-cobalt-chromium inikeza ukumelana nokuguguleka okuphezulu emalungeni axhumayo, kodwa akukho kuzo ezinikeza ukuguqulwa kwesigaba okubuyiselayo. Yingakho imboni yezokwelapha yamukela izindleko zokucubungula ze-Nitinol: ucingo lokuhola noma uhlaka lwe-stent olwenziwe ngocingo lwengxube ye-titanium-nickel lwenza imisebenzi engenziwa ezinye izinsimbi. Imikhawulo nayo ibalulekile, futhi abathengi kufanele bayihlelele — i-Nitinol inzima ukuyicubungula, izakhiwo zayo zizwela umlando wokwelashwa ngokushisa, futhi ukuhlanganisa ngokushisela okujwayelekile kwe-fusion kunciphisa ukuziphatha kokuguqulwa.

Ukusebenza nomkhiqizi oncibilikisa, osebenza, odonsa, oqondisa, ohlola futhi apakishe ngaphansi kohlelo olulodwa lwekhwalithi kunciphisa isikhathi sokuphendula phakathi kokucaciswa nokulethwa. I-Baoji Dong Intec Metal Materials Co., Ltd. ihlanganisa ukujula kokucubungula izinsimbi ezingavamile, indawo yase-Baoji ngaphakathi kweqoqo le-Titanium City yase-China, ubuchwepheshe be-spring alloy obuyimfihlo kanye nemodeli yesevisi elungele ukuthunyelwa kwamanye amazwe. Izinkampani ezifuna izilinganiso ze-titanium-nickel alloy round bar, i-titanium-nickel alloy wire, imikhiqizo ye-titanium ehambisanayo noma izingxenye ze-alloy ezenziwe ngokwezifiso zingabuyekeza konke okunikezwayo ku-Ikhasi Elisha futhi bathumele imidwebo yabo, ububanzi kanye nezidingo zobuningi ukuze kuhlolwe. Ukucaciswa okucacile kanye nengxoxo yezobuchwepheshe kusenesikhathi kuhlala kuyindlela esheshayo yokuphumelela kuhlelo lwe-Nitinol.

I-titanium-nickel alloy round bar iyisimo esiyisilinda esiqinile esingaphelele, ngokuvamile ububanzi bayo bungu-3 mm kuya ku-100 mm, esetshenziselwa ukusebenza ngomshini, ukusika nge-laser kanye nezingxenye zesakhiwo. I-titanium-nickel alloy wire idonswa ibe nobubanzi obuncane kakhulu, ngokuvamile obungu-0.05 mm kuya ku-8 mm, futhi ihlinzekwa ngama-spools noma ngobude obuqondile bama-guidewires, ama-archwires nama-springs. I-chemistry ye-Nitinol engaphansi ingafana, kodwa i-wire idinga ama-cold-drawing passes amaningi kakhulu kanye nokulawulwa kobubanzi okuqinile.

I-round bar ivamise ukukhiqizwa phakathi kuka-3 mm no-100 mm, kanti i-ground noma i-polished medical stock iyatholakala engxenyeni encane yalolo hla. I-Nitinol wire ivamise ukuba phakathi kuka-0.05 mm no-8 mm, kanti ama-medical grades agxile phakathi kuka-0.1 mm no-1.2 mm. Osayizi abangajwayelekile abaphakathi nendawo bangase bacashunwe njengama-custom production runs.

Yebo. I-titanium-nickel alloy round bar yezinga lezokwelapha kanye nocingo lwe-titanium-nickel alloy kungakhiqizwa ngokwe-ASTM F2063 ngezinto ezilawulwayo ze-interstitial kanye nokulandelelwa okuphelele kwe-heat-lot. Isitokwe sezokwelapha ngokuvamile sidinga ukuhlanzeka kwendawo eqinile, ukuqedwa okungenayo i-oxide kanye namazinga okushintsha abhalisiwe. Abathengi kufanele basho izinga elisebenzayo kanye nekilasi ledivayisi esigabeni sokubuza.

Izinga lokushisa lokuguqulwa lilawulwa ngokuyinhloko ngesilinganiso se-nickel-to-titanium kanye nokuqukethwe kwe-interstitial, ikakhulukazi umoya-mpilo kanye ne-carbon. Ngemuva kokuncibilika, ukucutshungulwa kwe-thermo-mechanical kanye nezinhlelo zokufaka i-annealing kuyalungiswa ukuze kubekwe iphuzu lokugcina le-austenite. Ukushisa ngakunye kuqinisekiswa nge-differential scanning calorimetry noma ukuhlolwa kwe-resistivity ngaphambi kokukhishwa.

Inani elincane loku-oda lamadayamitha akhethekile e-Nitinol ngokuvamile liqala ngamakhilogremu ambalwa, kuyilapho indunduma eyindilinga ejwayelekile ingase ikotshwe ngobude noma nge-lot. Isikhathi sokuhola sincike kumadayamitha, inhloso yezinga lokushisa lokuguqulwa kanye nokuqedwa kwendawo, futhi osayizi abangajwayelekile ngokuvamile badinga amaviki ambalwa. Osayizi abasitokini bangathunyelwa ngokushesha okukhulu.

I-Nitinol idinga ukuncibilika kwe-vacuum, ukudonswa kabili okubandayo kanye nokushisisa okuphindaphindiwe, kanye nokulawulwa okuqinile kokwakheka, konke lokhu okunyusa izindleko zokuguqulwa. Izithelo ziphansi ngoba ingxubevange iqina ngokushesha futhi kunzima ukuyisebenza. Ukusebenza okuvelayo — i-superelasticity kanye nenkumbulo yokuma — akutholakali ensimbi engagqwali noma kuma-alloys ajwayelekile e-titanium.

Imishini yezokwelapha iyona esebenzisa kakhulu, ilandelwa yizindiza, izimoto, uwoyela negesi, ukucubungula kwamakhemikhali kanye ne-electronics. Ukusetshenziswa kwezokwelapha kugxile kuma-stents, ama-guidewires kanye nama-orthodontic archwires, kuyilapho izindiza zisebenzisa ama-Nitinol couplings kanye nama-actuators. Izicelo zezimboni zifaka ama-thermostatic valves, izinzwa kanye nokuxhumana kwe-spring.

Gcina impahla endaweni eyomile, ehlanzekile kude nama-chloride namakhemikhali anolaka. Gcina ama-spool evalekile ne-desiccant kuze kube yilapho i-wire isilungele ukufakwa ekukhiqizeni, futhi gwema ukugoba noma ukugoqa okubukhali. Phatha i-bar ngamathuluzi anobuso obuthambile ukuvimbela ukulimala kwendawo okungase kuqale imifantu yokukhathala.

Nikeza ububanzi, ukubekezelelana, ubude noma ifomethi ye-spool, ukuqedwa kwendawo, isimo, inhloso yokushisa okuguqulwayo, izinga elisebenzayo, inani kanye nosuku lokulethwa oludingekayo. Ukwengeza uhlelo lokusetshenziswa okuhlosiwe kusiza isigayo ukuthi sincomela indlela efanele yokucubungula. Imidwebo noma izingxenye eziyisampula ziwusizo ezintweni ezenziwe ngokwezifiso noma ze-OEM.

I-Baoji Dong Intec isebenza ngaphakathi kweqoqo leDolobha leTitanium laseChina, okuyinika ukufinyelela emandleni avuthiwe okuncibilikisa, ukusebenza nokuhlola izinsimbi ezingavamile. Inkampani icubungula i-titanium, ingxube ye-titanium-nickel, i-nickel, i-tungsten, i-molybdenum nezinye izinsimbi ezingavamile zibe yizinduku, izintambo, amashubhu, amapuleti nemikhiqizo eqediwe. Iphinde ikhiqize izipringi ze-titanium nezingxenye zensimbi ezenziwe ngokwezifiso, futhi isekela osayizi abenziwe ngokwezifiso, amabanga ezokwelapha nawezimboni, nokupakishwa kwezinga lokuthumela ngaphandle.
