Ma ke kahua ākea o ka ʻepekema mea,nā huahana silicon carbideke lilo mālie nei i "aloha" o nā ʻoihana he nui ma muli o ko lākou mau waiwai kū hoʻokahi. ʻO kona kūpaʻa maikaʻi loa i ka ʻaʻahu e hoʻomālamalama ai i nā noi like ʻole. I kēia lā, e luʻu pū kākou i ke kūpaʻa ʻaʻahu o nā huahana silicon carbide.
ʻO ke silicon carbide, mai kahi kuanaʻike o ka hoʻohuihui kemika, he hui i hana ʻia mai nā mea ʻelua, ʻo silicon a me ke kalapona, ma nā mahana kiʻekiʻe. He ʻokoʻa loa kona ʻano kristal, kahi e hāʻawi ai i ka silicon carbide me kahi moʻo o nā waiwai maikaʻi loa, a ʻo ka paʻakikī kiʻekiʻe ke kumu nui no kona kūpaʻa ʻana i ka ʻaʻahu. He kiʻekiʻe loa ka paʻakikī o ka silicon carbide, me ka paʻakikī Mohs ma kahi o 9.5, he emi iki wale nō ia ma mua o ka daimana paʻakikī loa ma ke ʻano. ʻO ia ʻano paʻakikī kiʻekiʻe ke ʻano hiki iā ia ke pale aku i ka friction a me ka ʻaʻahu o waho, a mālama mau i kona kūpaʻa a me ka paʻa o ka hana i ke alo o nā ʻano hoʻohana paʻakikī like ʻole.
Mai kahi hiʻohiʻona microscopic, ʻo ka microstructure o nā huahana silicon carbide he paʻa loa. ʻAneʻane ʻaʻohe pores nui a i ʻole nā hemahema i loko, ʻo ia ka mea e emi ai ka maʻalahi o ka hōʻino ʻana i ke kūkulu ʻana a me ka hemo ʻana o nā mea i ka wā e hoʻopilikia ʻia ai. Ua like ia me kahi hale paʻa, me nā paia i hoʻopili paʻa ʻia e paʻakikī i nā ʻenemi ke uhaki. Ke loaʻa ka friction ma waena o nā mea o waho a me ka ʻili o ka silicon carbide, hiki i kona ʻano paʻa ke hoʻopuehu i ka ikaika frictional, pale i ka ʻaʻahu kūloko i hoʻokumu ʻia e ka noʻonoʻo ʻana o ke kaumaha, a hoʻomaikaʻi nui i ke kūpaʻa ʻana o ka ʻaʻahu holoʻokoʻa.
ʻO ke kūpaʻa kemika kekahi mea kaua nui no ke kūpaʻa ʻana o ka silicon carbide. I nā hiʻohiʻona hoʻohana pono he nui, ʻaʻole pono nā mea e kū i ka ʻaʻahu mechanical, akā hiki ke kū i ka ʻino kemika. He kūpaʻa kemika maikaʻi loa ka Silicon carbide, a ʻaʻole ia e maʻalahi i nā hopena kemika me nā mea ʻē aʻe e hiki ai ke hōʻino i ka hana, inā paha ma nā wahi kemika corrosive a i ʻole ma lalo o nā kūlana koʻikoʻi e like me ke kiʻekiʻe o ka mahana. ʻOiai ma lalo o nā kūlana koʻikoʻi o ke kiʻekiʻe o ka mahana a me ka corrosion no ka manawa lōʻihi, hiki i nā huahana silicon carbide ke mālama i ko lākou paʻakikī a me ke kūpaʻa o ke kūkulu ʻana, a hoʻomau i ka hōʻike ʻana i ke kūpaʻa ʻana o ka ʻaʻahu maikaʻi.
Ma nā noi hana, ua hōʻike piha ʻia nā pono o ke kūpaʻa ʻana o nā huahana silicon carbide. I ka ʻoihana mining, hoʻohana pinepine ʻia ka silicon carbide e hana i nā mea hana mining e like me nā ʻāpana wili, nā mea hana ʻoki, a pēlā aku. Pono kēia mau mea hana e kū i ke kaumaha nui o ka mīkini a me ka friction pinepine i ka wā o ke kaʻina hana o ka mining ores paʻakikī, ʻoiai ʻo silicon carbide, me kona kūpaʻa kiʻekiʻe, hiki ke hoʻolōʻihi i ke ola lawelawe o nā mea hana, hoʻemi i ka pinepine o ka hoʻololi ʻana i nā mea hana, a hoʻemi i nā kumukūʻai mining. Ua hoʻohana nui ʻia ka Silicon carbide i nā ʻāpana sila, nā bearings, a me nā ʻāpana ʻē aʻe o nā mīkini ʻoihana. Hiki iā ia ke hoʻemi pono i ke kūpaʻa o kēia mau ʻāpana i ka wā o ka hana wikiwiki a me ka friction pinepine, hoʻomaikaʻi i ka pono hana a me ke kūpaʻa o nā lako, a hoʻemi i nā kumukūʻai mālama.
Hoʻoholo ʻia ke kūpaʻa ʻana o nā huahana silicon carbide e ko lākou ʻano kemika kū hoʻokahi, ke ʻano kristal, a me nā ʻano microscopic. Me ka holomua mau o ka ʻenehana a me ka noiʻi hohonu ma ka silicon carbide, ke manaʻoʻiʻo nei mākou e hoʻohana ʻia nā huahana silicon carbide ma nā kahua hou aʻe, e lawe mai ana i nā manawa kūpono hou a me nā loli i ka hoʻomohala ʻana o nā ʻoihana like ʻole.
