ʻO nā ʻokoʻa ma waena o ka silika carbide ceramics a me ka silicon nitride ceramics

Ma ke kahua o nā mea holomua,silika carbide (SiC) a me silika nitride (Si3N4) seramikaua lilo i ʻelua o nā pūhui koʻikoʻi, kēlā me kēia me nā ʻano ʻokoʻa a me nā noi. He mea koʻikoʻi ka hoʻomaopopo ʻana i nā ʻokoʻa ma waena o kēia mau seramika ʻelua no nā ʻoihana e hilinaʻi nei i nā mea hana kiʻekiʻe. He ʻoihana ʻenehana kiʻekiʻe ʻo Shandong Zhongpeng Special Ceramics Co., Ltd. i ka hana ʻana i ka silicon carbide ceramics, e pāʻani ana i kahi hana koʻikoʻi ma kēia kahua, e hāʻawi ana i nā ʻike hohonu i nā waiwai a me nā noi o kēia mau mea.

ʻIke ʻia nā seramika Silicon carbide no ko lākou ʻano paʻakikī a me ke kūpaʻa wela. Loaʻa iā lākou ka silikoni a me ke kalapona, i hui pū ʻia e hana i kahi pūhui i loaʻa ka lole maikaʻi loa a me ka pale ʻana i ka corrosion. ʻO kēia ka mea i kūpono i ka silicon carbide ceramics no nā noi ma nā wahi paʻakikī e like me ka aerospace, automotive a me nā ʻoihana semiconductor. Hiki ke hoʻopau maikaʻi ka wela o ka Silicon carbide no nā noi wela kiʻekiʻe. Hoʻohana ʻo Shandong Zhongpeng Special Ceramics Co., Ltd. i kēia mau waiwai e hana i nā seramika silicon carbide kiʻekiʻe e kū ana i nā koi koi o nā ʻoihana like ʻole.

ʻO ka silikon nitride ceramics, ma ka ʻaoʻao ʻē aʻe, loaʻa nā waiwai mechanical maikaʻi loa, me ka ikaika kiʻekiʻe a me ka paʻakikī. ʻO nā seramika Si3N4, i haku ʻia me ke silikoni a me ka nitrogen, he kūpaʻa kūʻokoʻa i ka haʻalulu wela a he haʻahaʻa haʻahaʻa o ka hoʻonui wela i hoʻohālikelike ʻia me ka silicon carbide. ʻO kēia ka mea i koho maikaʻi loa i ka silicon nitride ceramics no nā noi e koi ana i nā mea e kū i ka hoʻololi wikiwiki ʻana, e like me nā turbines gas a me nā mea hana ʻoki. Hāʻawi pū ka microstructure kūʻokoʻa o Silicon nitride iā ia i ka paʻakikī haʻihaʻi maikaʻi loa, e lilo ia i mea koho no nā ʻoihana e koi ana i nā mea paʻa.

I ka hoʻohālikelike ʻana i nā mea ʻelua, ʻo kekahi o nā ʻokoʻa koʻikoʻi i kā lākou mau mea wela. Hiki i ka silicon carbide ceramics ke kū i nā wela kiʻekiʻe aʻe ma mua o ka silicon nitride ceramics, no laila kūpono lākou no ka hoʻohana ʻana i nā noi wela kiʻekiʻe. Eia nō naʻe, ʻo ka hiki i ka silicon nitride ke kū i ka haʻalulu wela e hāʻawi iā ia i mea maikaʻi i nā kaiapuni me ka nui o ka piʻi ʻana o ka wela. He mea koʻikoʻi kēia ʻokoʻa no nā ʻenekinia a me nā mea hoʻolālā i ke koho ʻana i kahi mea no kahi noi kikoʻī, ʻoiai ke koho ʻana o nā mea hiki ke hoʻopilikia nui i ka hana a me ke ola lawelawe.

ʻO kekahi ʻokoʻa nui ma waena o ka silicon carbide a me ka silicon nitride ceramics ʻo kā lākou paʻa kemika. Paʻa loa ka Silicon carbide i ka oxidation a hiki ke mālama i kāna mau waiwai i loko o nā wahi kemika corrosive. ʻO kēia ka mea kūpono no ka hana kemika a me nā noi hana semiconductor. I ka hoʻohālikelike ʻana, ʻaʻole hiki ke hana maikaʻi nā seramika nitride silicon, ʻoiai paʻa kemika, i kekahi mau kaiapuni corrosive. He mea koʻikoʻi ka hoʻomaopopo ʻana i kēia mau waiwai kemika no nā ʻoihana e hana ana i nā kūlana paʻakikī no ka mea e pili ana i ke koho waiwai a me ka hoʻolālā huahana.

ʻOkoʻa loa nā kaʻina hana no ka silicon carbide a me ka silicon nitride ceramics. Hoʻokumu pinepine ʻia nā seramika Silicon carbide e ka sintering, kahi kaʻina e pili ana i ka hoʻomehana ʻana i ka mea i kahi mahana ma lalo o kona wahi heheʻe e hoʻokō ai i ka densification. Hiki i kēia ala ke hana i nā ʻano paʻakikī a me nā ʻāpana kiʻekiʻe. ʻO ka ʻokoʻa, hana maʻamau ka silicon nitride ceramics me ka hoʻohana ʻana i ka hui ʻana o ka hoʻoili ʻana i ka pauka a me nā ʻenehana sintering, me ka paʻi wela a i ʻole ka hoʻopili ʻana. Hiki i kēia mau ʻokoʻa i nā kaʻina hana ke hoʻopili i nā waiwai hope o ka ceramic, me kāna microstructure a me nā waiwai mechanical.

Ma ke ʻano o ke kumukūʻai, ʻoi aku ka maikaʻi o ka silicon carbide ceramics ma mua o ka silicon nitride ceramics ma muli o nā mea maka a me ka ʻenehana hana. Eia nō naʻe, ʻo ka hana lōʻihi a me ka lōʻihi o ka silicon carbide hiki ke hōʻoia i ka ʻoi aku ka kiʻekiʻe o ka hoʻopukapuka mua, ʻoi aku hoʻi i nā noi i hiki ʻole i ka hemahema ke hopena i ka manawa hoʻomaha nui a i ʻole ka palekana. Hoʻokumu ʻo Shandong Zhongpeng Special Ceramics Co., Ltd. i ka hāʻawi ʻana i nā hopena maikaʻi loa me ka ʻole o ka hōʻemi ʻana i ka maikaʻi, e hōʻoia ana e loaʻa i nā mea kūʻai ke kumukūʻai maikaʻi loa no kā lākou hoʻopukapuka ʻana i nā seramika silicon carbide.

I ka hōʻuluʻulu ʻana, he mea nui ka ʻokoʻa ma waena o ka silicon carbide ceramics a me ka silicon nitride ceramics a hiki ke hoʻopilikia nui i kā lākou noi ma nā ʻano ʻoihana like ʻole. ʻOi aku ka ʻoi aku o ka silicon carbide i ke kiʻekiʻe o ka wela a me nā kaiapuni kemika, ʻoiai ke hōʻike nei ka silicon nitride i ka paʻakikī maikaʻi loa a me ke kūpaʻa ʻana i ka haʻalulu wela. He mea koʻikoʻi ka hoʻomaopopo ʻana i kēia mau ʻokoʻa no nā ʻenekinia a me nā mea hana i ke koho ʻana i nā mea no nā noi kikoʻī. Ma ke ʻano he mea hana nui o ka silicon carbide ceramics, ua kūpaʻa ʻo Shandong Zhongpeng Special Ceramics Co., Ltd. i ka holomua ʻana i ke kahua o nā seramika kiʻekiʻe, e hāʻawi ana i nā huahana kiʻekiʻe e kū ana i nā pono e ulu nei o ka ʻoihana hou. Ma ka hoʻohana ʻana i nā waiwai kūʻokoʻa o ka silicon carbide a me ka silicon nitride, hiki i nā hui ke hoʻolālā i kā lākou hoʻolālā a hoʻomaikaʻi i ka hana o kā lākou huahana, i ka hopena e hoʻonui ai i ka pono a me ka hilinaʻi o kā lākou hana.
