Yttrium Stabilized Zirconia, Kuj Paub Raws li YSZ
Feb 15, 2024
Yttrium stabilized zirconia, tseem hu ua YSZ, yog cov khoom siv uas tau siv dav hauv ntau lub lag luam vim nws cov khoom tshwj xeeb. YSZ yog ib hom zirconium oxide uas ruaj khov nrog yttrium oxide. Qhov sib ntxiv ntawm yttrium oxide hloov cov qauv siv lead ua ntawm zirconia, ua rau nws ruaj khov thiab tsis tshua muaj kev tawg thiab tawg.
YSZ yog qhov kev xaiv zoo tshaj plaws rau kev siv kub-kub vim nws nthuav tawm cov thermal stability zoo heev. Nws tuaj yeem tiv taus kub txog 2400 degree yam tsis muaj kev hloov pauv tseem ceeb hauv nws lub cev lossis tshuaj lom neeg. Qhov no ua rau YSZ zoo tagnrho rau kev siv ntau yam kev lag luam, suav nrog aerospace, tsheb, kev kho mob, thiab lub zog.
Lwm qhov txiaj ntsig tseem ceeb ntawm YSZ yog nws qhov siab tiv thaiv corrosion thiab hnav. Nws yog cov resistant rau acidic thiab yooj yim ib puag ncig, ua rau nws zoo meej rau siv nyob rau hauv chemical processing thiab kev kho mob implants. Nws tsis tshua muaj coefficient ntawm kev sib txhuam kuj ua rau nws zoo tagnrho rau siv nyob rau hauv bearings thiab lwm yam txav tshuab qhov chaw.
YSZ yog dav siv nyob rau hauv kev cog hniav vim nws superior biocompatibility thiab txhua yam muaj zog. Nws lub siab tawg toughness thiab qis thermal conductivity txo qhov kev pheej hmoo ntawm kev cog hniav tsis ua haujlwm thiab txhim kho qhov kev vam meej mus ntev ntawm kev cog hniav.
Hauv kev xaus, YSZ yog ib qho khoom tshwj xeeb nrog ntau yam kev siv hauv ntau yam lag luam. Nws cov khoom zoo heev ua rau nws zoo meej rau kev siv nyob rau hauv qhov chaw kub kub, kev ua tshuaj lom neeg, kev cog qoob loo kho mob, thiab ntau lwm yam kev siv. YSZ tau ua pov thawj tias yog cov khoom siv tseem ceeb uas ua rau muaj txiaj ntsig zoo, ua haujlwm ntev, thiab kev nyab xeeb ntawm ntau yam khoom thiab cov txheej txheem.
