ʻO ka hana sintering silicon carbide kahi ʻano hana no ka hoʻomākaukau ʻana i nā mea seramika hana kiʻekiʻe. Hoʻopili a kaomi ia i ka pauka silicon carbide me nā kemika ʻē aʻe ma lalo o nā kūlana wela kiʻekiʻe e hana i nā mea density kiʻekiʻe, paʻakikī kiʻekiʻe, kūpaʻa kiʻekiʻe a me ke kūpaʻa kiʻekiʻe i ka corrosion.
1. Ke ʻano hoʻomākaukau. ʻO ke kaʻina hana hoʻomākaukau o ka silicon carbide sintering reactive e komo pū ana me ʻelua mau ʻanuʻu: ka hopena a me ka sintering. I ke kahua hopena, hana ka pauka silicon carbide me nā kemika ʻē aʻe i nā mahana kiʻekiʻe e hana i nā hui me nā kiko heheʻe haʻahaʻa, e like me ka alumina, boron nitride a me ka calcium carbonate. Hiki i kēia mau hui ke hana ma ke ʻano he mea hoʻopaʻa a me nā mea hoʻopiha e kōkua i ka hoʻonui ʻana i ka hiki ke hoʻopaʻa a me ke kahe o nā pauka silicon carbide me ka hoʻemi ʻana i nā pores a me nā hemahema i loko o ka mea. I ke kahua sintering, sintered ka huahana hopena i nā mahana kiʻekiʻe e hana i kahi mea seramika mānoanoa. Pono e hoʻomalu ʻia nā mea e like me ka mahana, ke kaomi a me ka lewa pale i ke kaʻina hana sintering e hōʻoia i ka hana maikaʻi o ka mea. Loaʻa i ka mea seramika silicon carbide i loaʻa nā ʻano o ka paʻakikī kiʻekiʻe, ka ikaika kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka corrosion a me ke kūpaʻa kiʻekiʻe o ka ʻaʻahu.
2. Nā Waiwai. He nui nā waiwai maikaʻi o ka silicon carbide i hoʻopili ʻia e ka hopena, e hoʻohana nui ʻia ana i nā ʻano he nui. ʻO ka mea mua, he paʻakikī loa nā mea seramika silicon carbide a hiki ke ʻoki i nā mea paʻakikī e like me ke kila. ʻO ka lua, he maikaʻi ke kūpaʻa o ka ʻaʻahu o nā mea seramika silicon carbide a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma lalo o nā kūlana ʻino e like me ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe. Eia kekahi, he kiʻekiʻe ke kūpaʻa o ka palaho a me ke kūpaʻa o ka mahana kiʻekiʻe o nā mea seramika silicon carbide, a hiki ke hoʻohana ʻia no ka manawa lōʻihi i nā wahi palaho a me nā mahana kiʻekiʻe.
3. Nā kahua noi. Hoʻohana ʻia ka silicon carbide i hoʻopili ʻia e ka hopena ma nā ʻano he nui. No ka laʻana, ma ka ʻoihana hana, hoʻohana nui ʻia nā mea seramika silicon carbide i nā abrasives, nā mea ʻokiʻoki a me nā ʻāpana ʻaʻahu. ʻO kona paʻakikī kiʻekiʻe a me ke kūpaʻa ʻaʻahu e lilo ia i mea pono no ka ʻokiʻoki, wili a me ka wili ʻana
Kūpono no ka wili ʻana a me nā kahua ʻē aʻe. I ka ʻoihana kemika, hiki ke hoʻohana ʻia nā mea keramika silicon carbide e hana i nā kemika e like me ka sulfuric acid a me nā waikawa ikaika e like me ka hydrofluoric acid ma muli o ko lākou kūpaʻa kiʻekiʻe i ka pala a me ke kūpaʻa wela kiʻekiʻe. I ke kahua o ka aerospace a me ka pale kaua, hiki ke hoʻohana ʻia nā mea keramika silicon carbide e hana i nā pale missile a me nā mea pale wela no nā mokulele wikiwiki. Eia kekahi, hiki ke hoʻohana ʻia nā mea keramika silicon carbide i ke kahua biomedical o nā hui hana a me nā mea hana ʻokiʻoki orthopedic, no ka mea he maikaʻi ko lākou biocompatibility a me ke kūpaʻa ʻana i ka ʻaʻahu.
ʻO ka hana sintering silicon carbide kahi ʻano hana no ka hoʻomākaukau ʻana i nā mea seramika hana kiʻekiʻe. Hoʻopili a kaomi ia i ka pauka silicon carbide me nā kemika ʻē aʻe ma lalo o nā kūlana wela kiʻekiʻe e hana i nā mea density kiʻekiʻe, paʻakikī kiʻekiʻe, kūpaʻa ʻaʻahu kiʻekiʻe a me nā mea kūpaʻa corrosion kiʻekiʻe. Loaʻa i nā mea seramika Silicon carbide nā waiwai maikaʻi, e like me ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻaʻahu kiʻekiʻe, ke kūpaʻa corrosion kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe, no laila ua hoʻohana nui ʻia ia ma nā ʻano he nui e like me ka hana ʻana, ka ʻoihana kemika, nā kahua aerospace a me nā pale kaua a me nā kahua biomedical.
