Tungsten carbide hnav-resistant seem npog ntau yam kev lag luam carrees, kev sib tw ntawm cov khoom siv hluav taws xob, cov hlua khi, thiab cov kabmob tawv ntoo, thiab cov khoom siv tawv tawv. Vim tias lub zog hnav tsis kam tiv taus carbide, cov ntu no tseem muaj super hnav tsis kam. Txawm li cas los xij, kev siv ib puag ncig ntawm cov tungsten carbide hnav qhov chaw yuav tsum tau txhim kho txuas ntxiv kom txhim kho carbide hnav cov chaw tuaj yeem txhim kho cov hnav tsis kam.
Tungsten carbide muaj cov khoom siv zoo heev xws li siab tawv, siab elastic modulus, siab heev thiab hnav tsis kam. Nws yog dav siv nyob rau hauv tsuas yog thiab cov cuab yeej rho tawm cov cuab yeej, pwm, hnav-resistant seem, thiab lwm cov teb uas xav tau lub siab hnav tsis kam. Cov hnav cov khoom ntawm tungsten carbide yog cuam tshuam los ntawm cov yam xws li ib puag ncig uas nws tau siv thiab cov khoom ntawm alloy. Cov hnav tsis kam ntawm tungsten carbide hnav feem ntau yog txiav txim siab los ntawm microstructure thiab tshuaj lom neeg sib xyaw ua ke ntawm alloy. Cov txheej txheem tseem ceeb ntawm kev tso cai carbide yog: grain loj thiab ris luv cov ntsiab lus. Cov hnav tsis kam ntawm tungsten carbide chav kuj tseem cuam tshuam los ntawm cov khoom ntxiv xws li Boron.
Hauv kev txhim kho kev tshawb fawb thiab thev naus laus zis thiab cov khoom siv tseem ceeb, muaj kev puas tsuaj ntau, kev kub siab, oxidation, thiab lwm yam tshwm sim. Qhov kev puas tsuaj ntawm cov hlau tshwm sim los ntawm kev sib txhuam thiab hnav feem ntau pib ntawm qhov chaw. Kev siv cov kev tiv thaiv sab nrauv kom ncua thiab tswj hwm qhov kev puas tsuaj ntawm cov teeb meem ntawm kev ua kom carbide hnav-resistant seem. Yog li ntawd, ntau yam anti-anti-anti-ntawm cov khoom siv tshuab, ua plastron Carbide hnav-resistant seem, uas tsis tsuas yog nce cov alloy zog thiab kev cuam tshuam nyuaj los ntawm ntau dua 10%, tab sis kuj tseem ua rau carbide hnav-resistant seem.
Qhov chaw tiv thaiv saum npoo ntawm cov pa roj carbide rau kev tswj hwm lub ntsej muag ua ke, ntev lawv txoj kev pabcuam lub neej.
