ASTM F1295 Titanium hlau
ASTM F1295 yog tus qauv ntawm kev kho mob titanium bar thiab hlau, npog cov tshuaj, txhua yam thiab metallurgical xav tau rau wrought annealed, txias ua hauj lwm, los yog kub dov titanium -6 txhuas -7 niobium alloy (UNS R56700) bar / hlau rau phais implants.
Khoom Taw qhia
ASTM F1295 yog tus qauv ntawm kev kho mob titanium bar thiab hlau, npog cov tshuaj chemical, mechanical thiab metallurgical xav tau rau wrought annealed, txias ua hauj lwm, los yog kub dov titanium -6 txhuas -7 niobium alloy (UNS R56700) bar / hlau rau kev phais implants. ASTM F1295 tau tsim los siv rau hauv kev kho mob thiab phais cov ntawv thov txawm hais tias nws cov khoom muaj ze li ntawm Ti6Al4V, txawm li cas los xij Niobium tau hloov pauv rau Vanadium raws li tus neeg sawv cev beta stabilizing muab kev txhim kho biocompatibility. Yog li tam sim no ASTM F1295 titanium hlau thiab bar tau dav siv hauv kev lag luam khoom siv kho mob.
Nws yog feem ntau siv nyob rau hauv kev tsim cov orthopedic implants, xws li cov pob txha daim hlau thiab cov ntsia hlau, nrog rau cov hniav cog hniav. Cov hlau muaj zog thiab biocompatibility ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv cov khoom siv thauj khoom, xws li kev cog qoob loo thiab kev sib koom ua ke.
Ti-6Al-7Nb titanium hlau feem ntau yog tsim los ntawm kev sib xyaw ua ke ntawm melting, forging, thiab hlau kos cov txheej txheem, uas ua rau cov khoom siv nrog cov qauv microstructure zoo thiab zoo heev. Nws muaj nyob rau hauv ntau txoj kab uas hla thiab tuaj yeem ua tiav ntxiv, xws li los ntawm kev vuam lossis kev tsim, kom ua tau raws li cov qauv tsim tshwj xeeb.

Peb muaj cov pa sib xyaw ua ke thiab dov ntau lawm kab, ua kom nws descaled thiab pickled, sandblasted, tshuaj milled, hauv av, machined, tev, polished, los yog txias drew. Titanium -6 aluminium -7 niobium alloy yog muab ntau yaj nyob rau hauv arc thiab electron beam) ntawm ib hom conventionally siv rau reactive hlau.
Hauv daim ntawv thov kev kho mob
Nws yog cov khoom siv zoo uas tau siv dav hauv kev lag luam kho mob vim nws cov khoom zoo heev thiab biocompatibility. Nws yog ib qho tseem ceeb ntawm cov khoom siv rau kev tsim cov khoom siv kho mob, tshwj xeeb tshaj yog cov uas siv rau hauv daim ntawv thov load-bearing.
Ti-6Al-7Nb titanium hlau yog lwm cov titanium alloy feem ntau siv rau hauv kev kho mob, tshwj xeeb tshaj yog rau orthopedic implants. Cov alloy no paub txog nws cov biocompatibility zoo heev, corrosion kuj, thiab siab zog-rau-qhov hnyav piv, ua rau nws yog ib qho kev xaiv nrov rau cog xws li lub duav hloov thiab spinal fusion li.
Zoo ib yam li lwm cov titanium alloys siv hauv kev kho mob, Ti-6Al-7Nb yuav tsum tau ua raws li cov kev cai nruj rau kev nyab xeeb thiab kev ua tau zoo. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov khoom zoo Ti-6Al-7Nb titanium hlau thiab lwm cov ntaub ntawv ntawm cov hlau alloy uas tau tsim raws li cov qauv kev lag luam thiab kuaj kom meej kom lawv haum rau kev siv kho mob.
