Hnav thiab tsim kua muag yog ib qho teeb meem uas tsis tuaj yeem zam hauv kev tsim khoom thiab lub neej txhua hnub. Los ntawm cov khoom siv coj los siv thaum lub sijhawm ua haujlwm ua haujlwm rau huab cua thiab yaig ntawm lub tsev, hnav thiab tsim kua muag tsis tsuas yog txo cov khoom siv lub neej, tab sis kuj tseem tuaj yeem ua rau cov nqi tu thiab cuam tshuam rau kev tsim khoom. Ntawm ntau cov ntaub ntawv uas cuam tshuam nrog kev hnav thiab tsim kua muag, silicon carbide tau dhau los ua "tus neeg ua haujlwm nyuaj" vim nws qhov kev hnav zoo heev, ua ntsiag to tiv thaiv kev ua haujlwm ruaj khov ntawm ntau qhov chaw.
Yog vim li cassilicon carbidetuaj yeem dhau los ua "tus huab tais hnav-tiv taus" lus dag hauv nws cov qauv siv lead ua tshwj xeeb. Nws yog ib qho kev sib xyaw ua ke ntawm ob lub ntsiab lus, silicon thiab carbon, nruj sib koom ua ke los ntawm covalent bonds. Lub zog sib txuas ntawm cov tshuaj lom neeg daim ntawv cog lus no muab silicon carbide crystals tsis tshua muaj siab hardness - thib ob tsuas yog pob zeb diamond thiab cubic boron nitride, deb tshaj li cov hlau zoo tib yam thiab cov ntaub ntawv ceramic feem ntau. Cov qauv siv lead ua nyuaj zoo li "natural barrier", uas nyuaj rau kev puas tsuaj rau sab hauv cov qauv ntawm silicon carbide thaum cov khoom sab nraud sim rub los yog khawb qhov saum npoo, tiv taus hnav thiab tsim kua muag.
Ntxiv nrog rau nws cov hardness kom zoo dua, cov tshuaj stability ntawm silicon carbide kuj ntxiv rau nws hnav tsis kam. Nws tsis yooj yim rau cov tshuaj tiv thaiv nyob rau hauv ib puag ncig hnyav xws li kub thiab acidity, thiab yuav tsis ua rau cov qauv kev puas tsuaj vim oxidation los yog corrosion, yog li tuav ruaj khov hnav tsis kam. Txawm hais tias nws yog cov ntaub ntawv refractory nyob rau hauv high-temperature kilns los yog hnav-resistant cov ntaub ntawv nyob rau hauv mining machinery, silicon carbide yuav tuav nws txoj hauj lwm nyob rau hauv complex ib puag ncig thiab txo qhov poob los ntawm hnav thiab tsim kua muag.
Ntau tus neeg yuav tsis paub txog silicon carbide, tab sis nws twb permeated txhua yam ntawm peb lub neej. Nyob rau hauv kev tsim kho, hnav-resistant flooring nrog ntxiv silicon carbide tuaj yeem tiv taus lub tsheb sib tsoo thiab cov neeg ua haujlwm taug kev, tuav lub hauv av du thiab tiaj tus rau lub sijhawm ntev; Hauv kev tsim khoom, cov cuab yeej txiav thiab sib tsoo lub log ua los ntawm silicon carbide tau yooj yim txiav thiab txhuam cov khoom siv hlau nrog tsawg tsawg thiab tsim kua muag; Txawm nyob rau hauv lub tshav pob ntawm lub zog tshiab, silicon carbide ceramic bearings, nrog rau lawv cov khoom hnav-resistant, pab cov cuab yeej ua tau zoo thiab ua haujlwm ntev.
Raws li cov khoom siv zoo heev hnav-tiv taus, silicon carbide tsis tsuas yog ua kom pom qhov ntxim nyiam ntawm cov ntaub ntawv kev tshawb fawb, tab sis kuj tseem ua lub luag haujlwm tseem ceeb hauv kev txhawb kev txhim kho kev lag luam thiab txo kev siv zog. Nrog kev nce qib ntawm kev siv thev naus laus zis tas li, daim ntawv thov scenarios ntawm silicon carbide tseem nthuav dav. Nyob rau hauv lub neej yav tom ntej, tus huab tais "hnav-tiv taus" no yuav ua rau kom ntev thiab txhim khu kev qha guarantee rau ntau lub teb, ua kom pom cov khoom siv zog ntawm "kev ua siab ntev" nrog lub zog.
