Izitena zeSilicon Carbide
Isitena se-silicon carbideyinto enganyangekiyo eyenziwe nge-silicon carbide (SiC) njengeyona nto iphambili eluhlaza. Ineempawu zobulukhuni obuphezulu, ukumelana nokuguguleka okuphezulu, ukuqhuba kobushushu obuphezulu kunye nokumelana okuhle kokugqwala. Icandelo layo eliphambili yi-silicon carbide, kwaye umxholo uhlala uphakathi kwe-72% kunye ne-99%. Iindidi eziqhelekileyo ziquka izitena ze-silicon carbide ezibotshelelwe ngodongwe, izitena ze-silicon carbide ezibotshelelwe nge-silicon nitride, izitena ze-silicon carbide ezibotshelelwe nge-Sialon, njl.
Udidi:
Izitena ze-silicon carbide zingahlulwa zibe ziindidi ezilandelayo ngokweendlela ezahlukeneyo zokubopha:
Izitena ze-silicon carbide ezibotshelelwe ngodongwe:Udongwe lusetyenziswa njengesihlanganisi, lufanelekile kwiimeko ezifuna ukuhanjiswa kobushushu obuphezulu kunye nokumelana nokutshayiswa kobushushu.
Izitena ze-silicon carbide ezibotshelelwe kwi-silicon nitride:idutyulwa nge-nitriding reaction, inozinzo oluhle kakhulu kubushushu obuphezulu kunye nokumelana nokuguguleka.
Izitena ze-silicon carbide ezibotshelelwe kwi-Sialon:idityaniswe nomgubo we-Si3N4 kunye ne-Al2O3, ifanelekile kwiindawo ezinobushushu obuphezulu kunye neendawo zokubola kweekhemikhali.
Iimbonakalo:
Ubulukhuni obuphezulu:Ubunzima beMohs bezitena zesilicon carbide buyi-9, kwaye bunokumelana nokuguguleka okuphezulu kakhulu.
Ukuqhuba okuphezulu kobushushu:Inomoya ophezulu wokushisa kwaye ifanelekile kwiimeko ezifuna ukutshatyalaliswa kobushushu ngokukhawuleza.
Ukumelana nokugqwala:Izinzile kakuhle kwi-asidi kwaye ifanelekile kwiindawo ezahlukeneyo zobushushu obuphezulu kunye nokugqwala kweekhemikhali.
Ukumelana noxinzelelo lobushushu:Inokumelana kakuhle nokutsha kobushushu kwaye inokuhlala izinzile phantsi kotshintsho olukhawulezileyo lobushushu.
