- Uru nke mmeghachi omume bonded silicon carbide
Ngwaahịa Reaction Bonded Silicon Carbide (RBSC, ma ọ bụ SiSiC) na-enye oke ike/nguzogide abrasion na nkwụsi ike kemịkalụ dị egwu na gburugburu ebe siri ike. Silicon Carbide bụ ihe e ji aka rụọ nke na-egosipụta njirimara arụmọrụ dị elu gụnyere:
lNguzogide kemịkal dị mma.
Ike RBSC dị ihe fọrọ nke nta ka ọ bụrụ pasentị iri ise karịa nke ọtụtụ carbide silicon nke nwere nitride. RBSC bụ ezigbo ihe mgbochi nchara na seramiiki antioxidation. Enwere ike ịmepụta ya ka ọ bụrụ ụdị ihe mgbochi desulpurization (FGD).
lEzigbo iyi na iguzogide mmetụta.
Ọ bụ ihe kachasị elu na teknụzụ seramiiki na-eguzogide abrasion buru ibu. RBSiC nwere nnukwu ike iru nke dayamọnd. Emebere ya maka ojiji maka nnukwu ọdịdị ebe ọkwa silicon carbide na-adịghị mma na-egosipụta mmebi ma ọ bụ mmebi site na mmetụta nke nnukwu irighiri ihe. Ọ na-eguzogide nrụgide kpọmkwem nke obere irighiri ihe dị nro yana mmetụta na mmịpụta nke ihe siri ike dị arọ nwere slurries. Enwere ike ịmepụta ya n'ụdị dị iche iche, gụnyere ọdịdị cone na aka uwe, yana iberibe ndị ọzọ dị mgbagwoju anya emebere maka akụrụngwa ndị metụtara nhazi nke ihe eji arụ ọrụ.
lNguzogide okpomọkụ dị mma.
Ihe ndị e ji silicon carbide jikọta na mmeghachi omume na-enye ezigbo nguzogide okpomọkụ mana n'adịghị ka seramiiki ọdịnala, ha na-ejikọtakwa obere njupụta na ike igwe dị elu.
