ʻO nā bearings a me nā valves ʻelua o nā noi maʻamau no nā pōpō ceramic nitride silicon. Hoʻohana ka hana ʻana i nā pōpō nitride silicon i kahi kaʻina e hoʻohui i ke kaomi isostatic me ka sintering kaomi kinoea. ʻO nā mea maka no kēia kaʻina hana he silicon nitride fine pauka a me nā mea kōkua sintering e like me ka alumini oxide a me ka yttrium oxide.

No ka loaʻa ʻana o ka nui i makemake ʻia o ka pōpō nitride silicon, hoʻohana ʻia kahi huila daimana i ke kaʻina wili.

ʻO ka hoʻonui ʻia ʻana o ka mākeke pōpō silicon nitride e alakaʻi nui ʻia e nā waiwai kiʻekiʻe o kēia mau pōpō.

Hoʻohana ʻia kēia mau pōpō i nā bearings, kahi e hiki ai i nā ʻāpana ʻelua ke neʻe e pili ana i kekahi me ke kākoʻo pū ʻana i nā ukana mai ka ʻāpana e hoʻopaʻa i kahi. Hiki ke noʻonoʻo ʻia nā bearings e like me ka hui pū ʻana o kahi hui a me kahi kākoʻo hoʻouka. He haʻahaʻa haʻahaʻa haʻahaʻa a haʻahaʻa haʻahaʻa ka hoʻonui ʻana i ka wela me ka loaʻa ʻana o ke kūpaʻa kiʻekiʻe i nā hopena o ka haʻalulu wela. Ma waho aʻe o kēia, ʻaʻole pili kona ikaika i nā mahana a hiki i hoʻokahi kaukani degere Celsius. Hoʻohana ʻia nā pōpō silicone nitride i loko o ka mīkini mea hana spindles, niho drills, kaʻa kaʻa, aerospace, high speed air turbine bearings, a me nā ʻoihana biotechnology no ke kiʻekiʻe wela a me nā noi wikiwiki kiʻekiʻe.

Hāʻawi nā pōpō valve Silicon nitride i nā kūlana hana kūpono no nā ʻoihana o ka ʻimi ʻaila a me ka hoʻihoʻi. He kemika hoʻi, he ikaika kiʻekiʻe, a he kūʻē maikaʻi loa i ka abrasion a me ka corrosion. Eia kekahi, he mea māmā ia. Hiki iā ia ke pale aku i nā wela kiʻekiʻe i loaʻa i nā hana wai hohonu e hoʻomaikaʻi i kona kūpaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me kāna coefficient haʻahaʻa o ka hoʻonui wela.

ʻO ka hopena, ʻo ka piʻi ʻana o nā hana ʻimi aila a me ke kinoea i lilo i mea ikaika ma hope o ka hoʻonui ʻana o ka mākeke i ka wā i uhi ʻia e ka wānana. ʻO ka ʻokoʻa koʻikoʻi o ke kumukūʻai ma waena o nā bearings pōpō silicon nitride a me nā bearings pōpō kila ke kumu nui e hana ana i ka hoʻonui ʻana o ka mākeke. Manaʻo ʻia e loaʻa nā manawa hou no nā mea pāʻani i ka mākeke ma muli o ka hoʻonui ʻana i ka hoʻohana ʻana i nā pōpō silicon nitride i nā ʻano ʻoihana hoʻohana hope, ʻo ia hoʻi ka automotive, aerospace, medical, and chemical sector. nā mea ʻē aʻe.
