Hauv qee qhov kev lag luam, xws li kev khawb av, kev lag luam cement, kev lag luam hlau, kev lag luam tshuaj lom neeg, chaw tsim hluav taws xob thiab lwm yam, cov kav dej xa khoom siv feem ntau raug hnav. Yuav kom daws tau qhov teeb meem ntawm kev hnav kav dej, nws yog qhov tsim nyog siv cov kav dej uas tsis yooj yim hnav. Cov kav dej uas tsis yooj yim hnav feem ntau yog ib txheej tshwj xeeb ntawm cov txheej uas tsis yooj yim hnav ntxiv rau phab ntsa sab hauv ntawm cov kav dej, ua txheej tiv thaiv ntawm cov kav dej, ua lub luag haujlwm tiv thaiv kev hnav thiab tiv taus corrosion.
Cov khoom siv engineering hauv txhua qhov kev lag luam sib txawv, yog li muaj ntau txoj kev xaiv rau cov kav dej uas tiv taus hnav. Hauv kev xaiv cov ntaub ntawv hauv cov kav dej, feem ntau muaj: alumina, silicon carbide, zirconia, aluminium nitride, boron nitride, thiab lwm yam; Lwm cov yeeb nkab alloy uas tiv taus hnav, cov yeeb nkab tortoiseshell mesh uas tiv taus hnav, cov yeeb nkab steel thiab yas uas tiv taus hnav, cov yeeb nkab pob zeb cam khwb cia uas tiv taus hnav, cov yeeb nkab uas kub hnyiab uas tiv taus hnav, cov yeeb nkab alloy uas tsis tshua muaj neeg siv, thiab lwm yam. Muaj ntau hom, raws li qhov xwm txheej ntawm cov khoom siv engineering, xaiv cov yeeb nkab uas tiv taus hnav kom haum.
Ntawm lawv,alumina ceramic composite yeeb nkabyog qhov kev xaiv pheej yig tshaj plaws, nws muaj kev tiv thaiv kev hnav siab, sab hauv yog corundum ceramic, Moh hardness ntawm ntau dua 9, kev tiv thaiv kev hnav zoo dua li lwm cov ntaub ntawv. Tib lub sijhawm, cov ceramic hauv pem teb kuj muaj cov yam ntxwv ntawm kev tiv thaiv kub siab, kev tiv thaiv corrosion, tuaj yeem siv rau qhov kub siab lossis corrosive tej yam kev mob. Cov yeeb nkab sib xyaw ua ke yog lub teeb hauv qhov hnyav, nrog flange, vuam, kev sib txuas sai, kev tsim kho yooj yim dua. Xav txog txhua qhov zoo, cov yeeb nkab sib xyaw ua ke yog qhov kev xaiv zoo tiag tiag. Yog li ntawd, nws tau txais kev nyiam los ntawm ntau thiab ntau lub tuam txhab.
