Nā waiwai o ka carbide silikona i hoʻopaʻa hou ʻia
ʻO ka carbide silicon recrystallized (R-SiC) he mea hana kiʻekiʻe me ka paʻakikī lua wale nō i ke daimana, i hana ʻia ma kahi wela kiʻekiʻe ma luna o 2000 ℃. Mālama ia i nā waiwai maikaʻi he nui o SiC, e like me ka ikaika wela kiʻekiʻe, ke kūpaʻa ʻana i ka corrosion ikaika, ke kūpaʻa oxidation maikaʻi loa, ke kūpaʻa haʻalulu maikaʻi a pēlā aku.
● ʻO nā mea mechanical maikaʻi loa. ʻO ka carbide silicon recrystallized he kiʻekiʻe aʻe ka ikaika a me ka ʻoʻoleʻa ma mua o ke kalapona kalapona, ke kūpaʻa hopena kiʻekiʻe, hiki ke pāʻani i ka hana maikaʻi i nā wahi wela wela, hiki ke pāʻani i ka hana counterbalance maikaʻi i nā ʻano kūlana. Eia kekahi, loaʻa iā ia ka maʻalahi maikaʻi a ʻaʻole maʻalahi i ka pōʻino e ka hoʻolōʻihi ʻana a me ke kulou ʻana, kahi e hoʻomaikaʻi nui ai i kāna hana.
● Kiʻekiʻe corrosion kū'ē. ʻO ka carbide silicon recrystallized he kiʻekiʻe ka corrosion kū'ē i nāʻano media likeʻole, hiki ke pale i ka erosion o nāʻano media corrosive, hiki ke mālama i kona mau mea mechanical no ka manawa lōʻihi, he paʻa ikaika, iʻoi aku ka lōʻihi o ke ola. Eia kekahi, loaʻa iā ia ka paʻa wela maikaʻi, hiki ke hoʻololi i kekahi ʻano o nā loli wela, hoʻomaikaʻi i kāna hopena noi.
● ʻAʻole e emi ka sintering. No ka emi ʻole o ke kaʻina hana sintering, ʻaʻohe koʻikoʻi koena e hoʻoneʻe i ka deformation a i ʻole ka haki ʻana o ka huahana, a hiki ke hoʻomākaukau ʻia nā ʻāpana me nā ʻano paʻakikī a me ka pololei kiʻekiʻe.
