Ukuphonononga iiMveliso zeSilicon Carbide: Kutheni le nto iNgxwaba yabo yokuNxitywa ibalasele kangaka

Kwinkalo enkulu yesayensi yezinto,iimveliso ze-silicon carbidengokuthe ngcembe baba "intanda" yamashishini amaninzi ngenxa yeempawu zabo ezizodwa. Ngokukodwa ukuchasana kwayo okugqwesileyo kwenza ukuba kukhanye kwizicelo ezahlukeneyo. Namhlanje, makhe sihlolisise ukunxitywa kweemveliso ze-silicon carbide kunye.
I-silicon carbide, ukusuka kumbono wokwakheka kweekhemikhali, i-compound eyenziwe kwizinto ezimbini, i-silicon kunye nekhabhoni, kumaqondo aphezulu okushisa. Ubume bayo bekristale buhluke kakhulu, obunika i-silicon carbide kunye noluhlu lweempawu ezigqwesileyo, kunye nobunzima obuphezulu sisiseko esibalulekileyo sokumelana nokunxiba. Ukuqina kwesilicon carbide kuphezulu kakhulu, kunye nobunzima be-Mohs obujikeleze i-9.5, bungaphantsi kancinci kweyona diamond inzima kwindalo. Ubulukhuni obuphezulu obunjalo buthetha ukuba inokuxhathisa ngokufanelekileyo ukungqubana kunye nokunxiba kwangaphandle, kwaye igcine ingqibelelo yayo kunye nozinzo lokusebenza ebusweni beendawo ezahlukeneyo zokusetyenziswa.
Ukusuka kumbono we-microscopic, i-microstructure yeemveliso ze-silicon carbide zixinene kakhulu. Kukho phantse akukho pores ezinkulu okanye iziphene ngaphakathi, nto leyo eyenza ukuba kungabi lula ukonakaliswa kwesakhiwo kunye ne-detachment yempahla xa iphantsi kwengxabano. Kufana nenqaba eyomeleleyo, eneendonga ezidityaniswe ngokuqinileyo ekunzima ukuba iintshaba zigqobhoze. Xa kukho ukungqubuzana phakathi kwezinto zangaphandle kunye nomphezulu we-silicon carbide, isakhiwo sayo esixineneyo sinokusasaza amandla okukhuhlana, ukuphepha ukunxiba kwendawo okubangelwa kugxininiso loxinzelelo, kwaye kuphuculwe kakhulu ukuxhathisa kokunxiba.

Uzinzo lwekhemikhali lukwasisixhobo esikhulu sokumelana nokunxiba kwesilicon carbide. Kwiimeko ezininzi zesicelo esisebenzayo, izixhobo azifuneki nje ukumelana nokunxiba koomatshini, kodwa zinokujongana nokukhukuliseka kweekhemikhali. I-Silicon carbide inozinzo olugqwesileyo lweekhemikhali, kwaye ayinakukwazi ukuphendulwa kweekhemikhali kunye nezinye izinto ezinokubangela ukuthotywa kwentsebenzo, nokuba kukwiimeko zemichiza ezonakalisayo okanye phantsi kweemeko ezinzima ezifana nokushisa okuphezulu. Naphantsi kweemeko ezinzima zobushushu obuphezulu kunye nomhlwa ixesha elide, iimveliso ze-silicon carbide zisenako ukugcina ubulukhuni kunye nokuthembeka kwesakhiwo, kwaye ziqhubeke nokubonisa ukuxhathisa okulungileyo.
Kwizicelo ezisebenzayo, izibonelelo zokumelana nokunxiba kweemveliso ze-silicon carbide ziboniswa ngokupheleleyo. Kwishishini lezemigodi, i-silicon carbide isoloko isetyenziselwa ukuvelisa izixhobo zemigodi ezifana ne-drill bits, izixhobo zokusika, njl. Ezi zixhobo kufuneka zimelane noxinzelelo olukhulu lomatshini kunye nokukhuhlana rhoqo ngexesha lenkqubo yemigodi enzima, ngelixa i-silicon carbide, kunye nokumelana kwayo okuphezulu, inokwandisa kakhulu ubomi benkonzo yezixhobo, ukunciphisa umthamo wokutshintshwa kwesixhobo, kunye neendleko eziphantsi zemigodi. I-silicon carbide nayo isetyenziswe ngokubanzi kumacandelo okutywina, iibheringi, kunye nezinye iindawo zoomatshini boshishino. Inokunciphisa ngokufanelekileyo ukunxiba kwezi zixhobo ngexesha lokusebenza ngesantya esiphezulu kunye nokungqubuzana rhoqo, ukuphucula ukusebenza kakuhle kunye nokuzinza kwezixhobo, kunye nokunciphisa iindleko zokugcina.
Ukumelana nokunxiba kweemveliso ze-silicon carbide kuchongwa kukwakheka kweekhemikhali ezizodwa, ubume bekristale, kunye neempawu ezincinci. Ngenkqubela phambili eqhubekayo yetekhnoloji kunye nophando olunzulu kwi-silicon carbide, sikholelwa ukuba iimveliso ze-silicon carbide ziya kusetyenziswa kwiinkalo ezininzi, ezizisa amathuba amatsha kunye notshintsho kuphuhliso lwamashishini ahlukeneyo.
