Silicon nitride ihujwe na silicon karbide kare

Silicon nitride yahujwe na silicon karbide

Si3N4 ihujwe na SiC ceramic yamashanyarazi, ivangwa nifu nziza ya SIC nziza nifu ya Silicon, nyuma yamasomo yo guterera kunyerera, reaction yagabanutse munsi ya 1400 ~ 1500 ° C.Mugihe cyamasomo yo gucumura, kuzuza Azote nziza cyane mu itanura, noneho silicon izakorana na Nitrogen ikabyara Si3N4, So SiNN4 ibikoresho bya SiC bihujwe rero na nitride ya silicon (23%) na karubide ya silicon (75%) nkibikoresho nyamukuru , ivanze nibikoresho kama, kandi bigizwe nuruvange, gusohora cyangwa gusuka, hanyuma bikozwe nyuma yo gukama na azote.

Ibiranga ibyiza:

1.High kwihanganira ubushyuhe
2.Ubushyuhe bwo hejuru bwumuriro no kurwanya ihungabana
3.Imbaraga zumukanishi hamwe no kurwanya abrasion
4.Imbaraga nziza zingirakamaro no kurwanya ruswa

Dutanga ubuziranenge kandi bwuzuye bwakozwe na NSiC ceramic ibice bitunganywa na

1.Gucuranga
2.Gusoma
3.Uni Kanda
4.Gukanda
