ʻO ka hoʻomākaukau ʻana a me nā waiwai o nā keramika carbide silicon ma o ka hopena sintering

ʻO Silicon carbide (SiC) kahi hui covalent i hana ʻia me ke kalapona a me ka silicon a ua ʻike ʻia no kona mau waiwai maikaʻi loa, me ke kūpaʻa kiʻekiʻe o ka ʻaʻahu, ke kūpaʻa haʻalulu wela, ke kūpaʻa ikaika o ka corrosion a me ke alakaʻi wela kiʻekiʻe. ʻO kēia mau waiwai e hoʻolilo i ka silicon carbide i mea kūpono no nā ʻano noi like ʻole ma nā ʻoihana he nui, me ka aerospace, ka hana mīkini, nā petrochemicals, ka hoʻoheheʻe metala a me nā mea uila. Kūpono loa no ka hana ʻana i nā ʻāpana pale ʻaʻahu a me nā ʻāpana kūkulu wela kiʻekiʻe. ʻO ka hoʻomohala ʻana o nā keramika silicon carbide i hoʻopili ʻia e ka hopena ua hoʻokani i kahi kuleana koʻikoʻi i ka hoʻolaha ʻana i nā noi ʻoihana o kēia mea versatile.

ʻO ke ʻano hana kuʻunanā keramika silicon carbide i hoʻopili ʻia e ka hopenaʻo ia ke hoʻohana ʻana i ka pauka silicon carbide i hui pū ʻia me kahi liʻiliʻi o ka pauka kalapona. Ke hele nei ka hui ʻana i kahi hopena siliconization wela kiʻekiʻe e hana i kahi mea keramika mānoanoa. Eia nō naʻe, ʻaʻole nele kēia hana kuʻuna i kona mau hemahema. Hōʻike ʻia ke kaʻina hana sintering e ka lōʻihi o ka manawa, ke kiʻekiʻe o ka mahana a me ka hoʻohana ʻana i ka ikehu kiʻekiʻe, e hopena ana i nā kumukūʻai hana kiʻekiʻe. I ka lilo ʻana o nā koi ʻoihana no nā ʻano a me nā ʻano keramika silicon carbide i mea paʻakikī, ʻike nui ʻia nā palena o nā ʻano kuʻuna.

I nā makahiki i hala iho nei, ua lilo ka hoʻolauna ʻana o nā nanopowders silicon carbide i mea hoʻohiki e hoʻomaikaʻi i nā waiwai mechanical o nā keramika silicon carbide. ʻO ka hoʻohana ʻana i nā nanopowders hiki ke hana i nā keramika me nā densities sintered kiʻekiʻe a me nā ikaika flexural kiʻekiʻe. Eia nō naʻe, ʻoi aku ke kiʻekiʻe o ke kumukūʻai o ka nanopowder silicon carbide, pinepine ma mua o 10,000 yuan no kēlā me kēia tona, kahi mea e pale nui ai i ka hoʻohana nui ʻana a me ka hana nui. Pono kēia pilikia hoʻokele waiwai i ka ʻimi ʻana i nā mea maka a me nā ʻano hana ʻē aʻe e hana i ka hana ʻana o nā keramika silicon carbide i ʻoi aku ka hiki a me ke kumukūʻai kūpono.

Eia kekahi, ʻo ka hiki ke hana i nā ʻano paʻakikī a me nā ʻāpana nui e wehe i nā ala hou no nā noi keramika silicon carbide. Hiki i nā ʻoihana e koi ana i nā hoʻolālā paʻakikī a me nā mea hana kiʻekiʻe ke pōmaikaʻi mai kēia ʻano hoʻomākaukau hou. ʻO ka maʻalahi o ka hoʻolālā a me ka hiki ke hana nui o nā keramika silicon carbide kiʻekiʻe ke alakaʻi i nā holomua nui ma nā wahi e like me ka aerospace a me nā mea uila kahi e koʻikoʻi ai ka hana o nā mea.
