Teeb meem hnav yog ib qho teeb meem nyuaj rau ntau tus neeg siv tam sim no. Corrosion, hnav thiab tawg yog peb yam tseem ceeb ntawm cov khoom tsis ua haujlwm. Hnav tsis ua hauj lwm los ntawm kev sib txhuam nyiaj rau ntau tshaj 70% ntawm cov khoom puas. Cov hnav-resistant ceramic hauv ob sab phlu zoo daws qhov teeb meem no raws li kev ua haujlwm ntawm lub cev thiab cov yam ntxwv xws li cov khoom siv, qhov loj me, hardness thiab ceev. Tom ntej no, cia's saib seb txoj hauv kev zoo muaj.
1. Cov khoom siv raw ntawm ceramic hauv ob sab phlu yog siab purity α- Rau alumina hmoov, ZTA series kuj siv zirconia nrog zoo heev toughness raws li lub toughening hloov tivthaiv kom zoo txhim kho cov hnav tsis kam thiab cuam tshuam cov khoom ntawm alumina.
2. Lub centrifugal spray granulation ntauwd yog saws los xyuas kom meej tias cov hmoov granulation yog sib npaug thiab muaj fluidity zoo.
3. Ceramic hauv ob sab phlu yog tsim los ntawm isostatic nias, uas muaj siab extrusion ntsuab lub cev ceev thiab yog yooj yim rau sintering.
4. Cov txheej txheem sintering nruj thiab raug lub computer tswj qhov kub thiab txias txo qhov tsim ntawm cov pores sab hauv thiab xyuas kom meej tias cov khoom sintered yog ntom thiab tsis deformed.
Los ntawm cov lus qhia saum toj no, kev siv cov hnav-resistant ceramic hauv ob sab phlu tuaj yeem txhim kho cov khoom tsim tau zoo, txo kev siv hluav taws xob thiab txo cov peev txheej tiv thaiv. Kuv vam tias cov lus teb no tuaj yeem pab koj.
