1. NA PONO O KA REACTION BONDED SILICON CARBIDE

Hāʻawi nā huahana Reaction Bonded Silicon Carbide (RBSC, a i ʻole SiSiC) i ka paʻakikī paʻakikī / kūʻē abrasion a me ke kūpaʻa kemika koʻikoʻi i nā kaiapuni ʻino. ʻO Silicon Carbide kahi mea synthetic e hōʻike ana i nā hiʻohiʻona hana kiʻekiʻe e like me:

lKūleʻa kemika maikaʻi loa.

ʻO ka ikaika o RBSC he 50% ʻoi aku ka nui ma mua o ka nui o ka nitride paʻa silicon carbide. ʻO RBSC ka maikaʻi o ka corrosion resistance a me ka antioxidation ceramic.

lʻO ka ʻaʻahu maikaʻi a me ke kūpaʻa hopena.

ʻO ia ke kiʻekiʻe o ka ʻenehana seramika kūpaʻa abrasion nui. He kiʻekiʻe ka paʻakikī o RBSiC e pili ana i ka daimana. Hoʻolālā ʻia no ka hoʻohana ʻana i nā noi no nā ʻano nui kahi e hōʻike ana nā māka refractory o ka silicon carbide i ka lole abrasive a i ʻole ka pōʻino mai ka hopena o nā mea nui. Kūleʻa i ka hoʻopili pololei ʻana i nā ʻāpana māmā a me ka hopena a me ka hoʻoheheʻe ʻana i ka abrasion o nā paʻa kaumaha i loaʻa nā slurries. Hiki ke hana ʻia i loko o nā ʻano ʻano like ʻole, me nā ʻano cone a me nā lima lima, a me nā ʻāpana ʻenehana paʻakikī i hoʻolālā ʻia no nā lako hana i ka hana ʻana i nā mea maka.

lKūleʻa haʻalulu wela maikaʻi.

Hāʻawi ʻia nā ʻāpana carbide silicon i hoʻopaʻa ʻia i ke kūʻē ʻana i ka haʻalulu wela akā ʻaʻole like me nā seramika maʻamau, ua hui pū lākou i ka haʻahaʻa haʻahaʻa me ka ikaika mechanical kiʻekiʻe.

lKa ikaika kiʻekiʻe (loaʻa ka ikaika ma ka mahana).

Hoʻopaʻa ʻia ʻo Silicon carbide i hoʻopaʻa ʻia i ka hapa nui o kona ikaika mechanical ma nā wela kiʻekiʻe a hōʻike i nā pae haʻahaʻa o ka kolo, e lilo ana ia i koho mua no nā noi lawe ukana ma ka laulā 1300ºC a 1650ºC (2400ºC a 3000ºF).
