Peb tsom mus nrhiav kom paub qhov zoo disfigurement los ntawm kev tsim khoom thiab muab cov kev pabcuam zoo tshaj plaws rau cov neeg siv khoom hauv tsev thiab txawv teb chaws tag nrho lub siab dawb paug rauTuam Tshoj Graphite Pwm thiab Graphite, Peb ntseeg tias tsim kom muaj kev sib raug zoo ntawm cov neeg siv khoom thiab kev sib raug zoo rau kev lag luam. Kev sib raug zoo nrog peb cov neeg siv khoom tau pab peb tsim cov saw hlau muaj zog thiab sau cov txiaj ntsig zoo. Peb cov kev daws teeb meem tau txais peb thoob plaws qhov kev lees paub thiab kev txaus siab ntawm peb cov neeg siv khoom thoob ntiaj teb.
Siliconized graphite yog cov khoom sib xyaw uas silicon carbide txuas rau saum npoo ntawm graphite substrate. Nws muaj cov yam ntxwv ntawm siab hardness, siab mechanical zog thiab hnav tsis kam ntawm silicon carbide, nrog rau nws tus kheej-lubricating zog thiab thermal shock kuj ntawm graphite. Nws yog ib qho zoo tagnrho cov ntaub ntawv sib txhuam thiab cov khoom siv foob, haum rau kev sib khi ntawm ntau yam twj tso kua mis, roj twj, tshuaj twj, thiab bearings ntawm ntau yam high-ceev thiab high-load lub ntsiab twj. Tsis tas li ntawd, siliconized graphite muaj qhov zoo oxidation tsis kam, thermal poob siab tsis kam, porosity tsawg, thiab qee yam hluav taws xob conductivity, thiab tuaj yeem siv los ua cov ntaub ntawv xws li hlau smelting crucibles thiab cov hlab ntsha.
Cov muaj pes tsawg leeg ntawm siliconized graphite yog ib yam, qhov saum npoo yog zoo ib yam nrog rau sab hauv, thiab muaj pes tsawg leeg ntawm silicon carbide thiab graphite yog adjustable. Qhov siab dua cov ntsiab lus ntawm silicon carbide, qhov ntau dua qhov ntom ntawm cov khoom, qhov siab dua lub zog compressive, thiab cov resistivity nce.
