He aha nā pōmaikaʻi a me nā pōʻino o ka silicon carbide i hoʻohālikelike ʻia me ka silicon nitride, aluminum oxide a me ka zirconia?

ʻO ka pōʻino nui loa okalapona kalaponaʻo ia ka paʻakikī o ka sinter!
ʻOi aku ke kumukūʻai o Silicon nitride!

ʻAʻole paʻa ka hoʻololi ʻana a me ka hopena paʻakikī o ka zirconia a i kekahi manawa kūpono. Ke hoʻopau ʻia kēia pilikia, ʻaʻole wale ka zirconia, hiki i ke kahua seramika holoʻokoʻa ke holomua! .

ʻOi aku ka maʻamau a ʻoi aku ka maikaʻi o ka alumina, a maikaʻi ke kūpaʻa wela.
ʻOi aku ka maikaʻi o ka pale ʻana o Zirconia ma mua o ka alumina a me ke kiʻekiʻe o ka mahana, akā ʻoi aku ka maikaʻi o kona pale ʻana i ka haʻalulu ma mua o ka alumina.
Loaʻa i ka Silicon nitride nā waiwai piha e like me ke kūpaʻa ʻana a me ke kūpaʻa haʻalulu wela, akā ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana ma mua o nā mea ʻelua. ʻO ka pipiʻi loa.
ʻO nā seramika alumina ka mea mua loa i hoʻohana ʻia. Kumu kūʻai haʻahaʻa, hana paʻa a me nā huahana like ʻole. ʻO ka mākeke ʻo ia ka alumina nui a nui loa, no ke aha? E hoʻohālikelike i nā mea hope ʻelua a e hoʻomaopopo ʻoe.

Hoʻohālikelike nuiʻia ma keʻano o ka hana a me ke kumukūʻai. A laila ʻoi aku ka maikaʻi mai ka mākeke kūʻai.
Ma ke ʻano o ke kumukūʻai, ʻo ka alumina ka mea liʻiliʻi loa, a ʻo ke kaʻina hana hoʻomākaukau ʻana i ka pauka ʻoi loa. Loaʻa i nā mea hope ʻelua nā hemahema i kēia ʻano, ʻo ia kekahi o nā bottlenecks e kāohi i ka hoʻomohala ʻana o nā mea hope ʻelua.
Ma keʻano o ka hana,ʻoi aku ka maikaʻi o nā mea mechanical e like me ka ikaika a me ka paʻakikī o ka silicon nitride a me ka zirconia ma mua o ka alumina. Me he mea lā ua kūpono ka hana kumukūʻai, akā i ka ʻoiaʻiʻo he nui nā pilikia.
Mai ka hiʻohiʻona o ka zirconia, he kiʻekiʻe ka paʻakikī ma muli o ke kū ʻana o nā stabilizers, akā ʻo kona paʻakikī kiʻekiʻe ka manawa. No ka laʻana, ma hope o ka waiho ʻia ʻana o ka mea zirconia i ka lewa no kekahi manawa, e nalowale ka paʻa a me ka hana ʻana e hāʻule nui a i ʻole ka haki ʻana! !! !! Eia kekahi, ʻaʻohe pae metastable i ka wela kiʻekiʻe, no laila ʻaʻohe paʻakikī kiʻekiʻe. No laila, hiki i ka hoʻohana ʻana i ka wela kiʻekiʻe a me ka mahana o ka lumi ke hoʻopaʻa nui i ka ulu ʻana o ka zirconia. Pono e ʻōlelo ʻia ʻo ia ka liʻiliʻi loa o nā mākeke ʻekolu.
Ma ke kamaʻilio e pili ana i ka nitride silika, ua lilo ia i mea kaulana i nā makahiki he ʻelua i hala, akā ʻoi aku ka paʻakikī o kāna kaʻina hana hoʻomākaukau huahana ma mua o ka alumina, ʻoi aku ka maikaʻi ma mua o ka zirconia, akā ʻaʻole maikaʻi e like me ka alumina.
