Hiki ke hoʻohana ʻia ka ʻenehana uhi silika carbide i ka wela kiʻekiʻe?

ʻO ka ʻenehana silicon carbide coating kahi ʻano o ka hana ʻana i ka papa silika carbide ma luna o ka ʻili o nā mea, me ka hoʻohana pinepine ʻana i ka deposition chemical vapor, physicochemical vapor deposition, melt impregnation, plasma mixing chemical vapor deposition a me nā ʻano hana ʻē aʻe e hoʻomākaukau ai i ka uhi silicon carbide, ʻoi aku ka kiʻekiʻe o ka uhi silicon carbide. ke kū'ē wela, ke kū'ē i ka corrosion, ke kū'ē o ka oxidation, ke kū'ē a me nā mea maikaʻi'ē aʻe. No laila, hoʻohana nui ʻia i ka wela kiʻekiʻe, ke kiʻekiʻe kiʻekiʻe, ka paʻakikī kaiapuni a me nā māla ʻē aʻe.

ʻO ke kaiapuni wela kiʻekiʻe kahi kahua koʻikoʻi o ka hoʻohana ʻana i ka uhi SIC. Hiki ke pilikia nā mea kuʻuna i ka hoʻonui ʻana, ka palupalu, ke ahi, ka oxidation a me nā pilikia ʻē aʻe i ka wela kiʻekiʻe, akā ʻo ka silicon carbide coating he kiʻekiʻe ka wela a hiki ke kū i ka corrosion a me ke koʻikoʻi wela i ke kiʻekiʻe wela. No laila, hiki ke hoʻohana i ka ʻenehana pale SIC i ka wela kiʻekiʻe.

Ma nā wela kiʻekiʻe, hiki ke hoʻohana ʻia nā uhi SIC ma nā wahi aʻe:

ʻO ka mea mua, aerospace

Hiki i nā ʻenekini lewa hou, nā ʻenekini rocket a me nā mea hana ʻē aʻe ke kū i ka wela kiʻekiʻe a me ke kaomi ʻana i nā kaiapuni hiki ke hoʻohana i ka uhi silicon carbide e hāʻawi i nā waiwai wela maikaʻi a me ke kūpaʻa ʻana. Eia kekahi, ma ke kahua o ka nui ākea, ka ʻimi honua, satellite, a me nā mea ʻē aʻe, hiki ke hoʻopili ʻia ka silicon carbide coating no ka pale ʻana i nā lako uila a me nā ʻōnaehana hoʻomalu mai ka radiation wela kiʻekiʻe a me nā kukui particle.

ʻO ka lua, ka ikehu hou

I loko o ke kikowaena pūnaewele nui, hiki i ka silicon carbide coating ke hāʻawi i ka ʻoi aku ka maikaʻi o ka hoʻololi ʻana o ke kelepona a ʻoi aku ka maikaʻi o ka paʻa, ʻo ia hoʻi, i hoʻopili ʻia i nā keʻena wahie wela kiʻekiʻe a me nā māla ʻē aʻe hiki ke hāʻawi i ke ola pākaukau kiʻekiʻe a me ka maikaʻi, e alakaʻi ana i ka hoʻomohala ʻana i nā ʻenehana ikehu hou.

3. ʻOihana hao a me ke kila

I ka ʻoihana hao a me ke kila, i ke kaʻina hana ma lalo o ke kiʻekiʻe o ka mahana wela, nā pōhaku lepo umu, nā mea refractory a me nā mea hana ʻē aʻe e like me nā paipu metala, nā valves a me nā mea ʻē aʻe e pono ai ka wela kiʻekiʻe, ka ʻino a me nā mea kūʻai aku, hiki ke hāʻawi aku ka silicon carbide coating i ka maikaʻi. hana palekana, hoʻomaikaʻi i ke ola lawelawe o nā lako.

4. ʻOihana Kimia

I ka ʻoihana kemika, hiki i ka hoʻohana ʻana i ka silicon carbide coating ke pale aku i nā mea kemika mai ka corrosion, oxidation a me ka hopena o ke kiʻekiʻe kiʻekiʻe a me ke kaomi kiʻekiʻe, hoʻomaikaʻi i ke ola lawelawe a me ka palekana o nā mea hana. I ka hōʻuluʻulu manaʻo, hiki ke hoʻohana ʻia ka ʻenehana hoʻopili silika carbide i nā ʻenehana wela kiʻekiʻe, e hāʻawi i ka hana palekana maikaʻi a me ke ola lawelawe, i ka wā e hiki mai ana, me ka hoʻomohala mau ʻana o ka ʻenehana hoʻomākaukau ʻana i ka silicon carbide coating, e ʻoi aku ka nui o nā kahua o ka hoʻohana ʻana i ka silicon carbide. ʻenehana uhi.
