Iipropati ze-silicon carbide ehlaziyiweyo
I-silicon carbide ehlaziyiweyo (i-R-SiC) yinto ephezulu yokusebenza enobunzima besibini kuphela kwidayimane, eyenziwe kubushushu obuphezulu obungaphezulu kwe-2000 ℃. Igcina iipropathi ezininzi ezigqwesileyo ze-SiC, ezinje ngamandla obushushu obuphezulu, ukuxhathisa okuqinileyo kwe-corrosion, ukuxhathisa okugqwesileyo kwe-oxidation, ukuchasana kakuhle nokothuka kwe-thermal njalo njalo.
● Iimpawu ezigqwesileyo zoomatshini. I-silicon carbide ehlaziyiweyo inamandla aphezulu kunye nokuqina kune-carbon fiber, ukuchasana kweempembelelo eziphezulu, kunokudlala ukusebenza kakuhle kwiindawo eziphakamileyo zokushisa, kunokudlala ukusebenza kakuhle kokulinganisa kwiimeko ezahlukeneyo. Ukongezelela, ibuye ibe nokuguquguquka okulungileyo kwaye ayonakaliswa lula ngokuzolula kunye nokugoba, okuphucula kakhulu ukusebenza kwayo.
● Ukumelana ne-corrosion ephezulu. I-silicon carbide ehlaziyiweyo inokumelana nokugqwala okuphezulu kwiindidi ezahlukeneyo zeendaba, inokuthintela ukukhukuliseka kweentlobo ezahlukeneyo zeendaba ezitshabalalisayo, inokugcina iipropathi zayo zemishini ixesha elide, inokuqina okuqinileyo, ukuze ibe nobomi obude benkonzo. Ukongezelela, ikwanayo nokuzinza okuhle kwe-thermal, iyakwazi ukulungelelanisa uluhlu oluthile lokutshintsha kweqondo lokushisa, ukuphucula umphumo wesicelo sayo.
● Ukuhlambalaza akufihli. Ngenxa yokuba inkqubo ye-sintering ayinciphisi, akukho xinzelelo olushiyekileyo luya kubangela ukuguqulwa okanye ukuqhekeka kwemveliso, kunye neengxenye ezinemilo enzima kunye nokuchaneka okuphezulu kunokulungiswa.
