Kugereranya imiterere ya keramik ya silicon carbide na keramik ya alumina

Sic ceramics ntabwo ifite gusa imiterere myiza ya mekanike mu bushyuhe bw'icyumba, nko gukomera cyane mu kugonda, kurwanya okiside nziza, kurwanya ingese, kudashira cyane no kudashyuha cyane, ahubwo inafite imiterere myiza ya mekanike mu bushyuhe bwinshi (imbaraga, kudacika intege, nibindi) mu bikoresho bya ceramic bizwi. Gushyushya gukanda, kudakanda, gushyuha cyane, ikintu kiranga silika carbide ni imbaraga z'ubushyuhe bwinshi, ibikoresho bisanzwe bya ceramic kuri dogere selisiyusi 1200 ~ 1400 imbaraga zizagabanuka cyane, naho silika carbide kuri dogere selisiyusi 1400 imbaraga zo kugonda zigakomeza ku rugero rwo hejuru rwa 500 ~ 600MPa, bityo ubushyuhe bwo gukora bushobora kugera kuri dogere selisiyusi 1600; Imiterere ya plate ya silika carbide ikomeye kandi iracikagurika, coefficient yo kwaguka ni nto, irwanya ubukonje kandi ishyushye, ntibyoroshye guhindura. Silicon carbide niyo ifite ubucucike buke, bityo ibice bya silika bikozwe muri silika carbide ni byo byoroshye cyane.

Alumina ceramic ni ubwoko bwa alumina (Al2O3) nk'igice cy'ingenzi cy'ibikoresho bya ceramic, bikoreshwa mu miyoboro minini ya firime ivanze. Alumina ceramic ifite ubushobozi bwo gutwara ibintu neza, imbaraga za mekanike n'ubushyuhe bwinshi. Ni ngombwa kumenya ko gukaraba hakoreshejwe ikoranabuhanga ari ngombwa. Ubudasaza bwayo bungana n'inshuro 266 z'icyuma cya manganese n'inshuro 171.5 z'icyuma cya chromium nyinshi. Alumina ceramic ni ubwoko bw'ibikoresho by'ubwirinzi byo mu rwego rwo hejuru, bikunze gukoreshwa mu gukora urupapuro rwo kwirinziza, impeta yo kwirinziza n'ibindi bice. Alumina ceramic ishobora kwihanganira ubushyuhe bwinshi kugeza kuri 1750℃ (ibipimo bya alumina birenga 99%).
