I nā makahiki i hala iho nei, ua loaʻa mālie ka uhi ʻana o ka silicon carbide a me ka noi ʻana, ʻoi aku ka nui o ke kiʻekiʻe kiʻekiʻe, ke kiʻekiʻe kiʻekiʻe, ka ʻaʻahu, ka corrosion a me nā kūlana hana koʻikoʻi ʻē aʻe, kahi i hiki ʻole ai i ka silicone coating ke hoʻokō i nā koi i kekahi ʻano, silicon carbide ua lilo ka uhi i koho kaulana o nā mea ʻokoʻa. ʻO ka uhi kalapona silikika, i ʻike ʻia hoʻi he kalapona silicide, he uhi pale ʻaʻahu i haku ʻia me ke kalapona a me ke silika. No laila, maikaʻi paha kēia uhi? E kamaʻilio e pili ana i kā mākou hopena.
ʻO ka mea mua, ʻo kekahi o nā mea maikaʻi o ka uhi silika carbide ʻo ia ka maikaʻi o ka pale ʻana. Ma nā kahua e like me nā kaʻa kaʻa kaʻa kiʻekiʻe, ka hana ʻana i nā mīkini, ka hana ʻana i ka mold, aerospace a me ka hoʻokele, ka hoʻohana ʻana i ka paʻakikī silika carbide coating, ʻoi aku ka maikaʻi o ka pale ʻana, no laila hiki iā ia ke hoʻomaikaʻi i ke ola lawelawe a me ka lōʻihi o ka mea. No nā mīkini a me nā mea pono e holo no ka manawa lōʻihi, hiki i ka silicified carbon coating material ke mālama i kekahi mau kumukūʻai, no ka mea hiki ke hōʻemi i ka lole a me ka waimaka o nā ʻāpana, hoʻolōʻihi i ke ola lawelawe o nā lako, a hoʻemi nui i nā kumukūʻai mālama.
ʻO ka lua, ʻo ka silicon carbide coating kekahi mau pale corrosion a me ka pale oxidation. I loko o nā ʻano like ʻole o ka waikawa, alkali a me nā mea corrosive media a me ke kiʻekiʻe o ka wela wela, ʻaʻole e ʻike ʻia ka uhi ʻana o ka silicon carbide i ka corrosion a me ka oxidation, i mea e hōʻoia ai i ka hoʻohana ʻana i nā mea i uhi ʻia a me ka maikaʻi.
Eia kekahi, ʻoi aku ka ikaika o ka adhesion o ka silicon carbide coating, hiki ke hoʻopaʻa paʻa ʻia i nā waiwai i uhi ʻia, i mea e hōʻoia ai i ka paʻa a me ka hilinaʻi o ke ola lawelawe. I ka hana ʻenehana a me ka hana ʻoihana, ma ke ʻano he ʻenehana uhi kiʻekiʻe, hiki iā ia ke hana hou i nā kiʻi paʻakikī a me nā ʻaoʻao kikoʻī, i mea e hoʻokō ai i nā pono o ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe kiʻekiʻe, kiʻekiʻe nā koi o nā huahana kūikawā.
ʻOiaʻiʻo, aia nā drawbacks i ka uhi silika carbide. ʻO ka mea mua, he kiʻekiʻe ke kumukūʻai hoʻomākaukau o ka uhi kalapona silicified, a ʻo ka hoʻohana ʻana iā ia e koi i ka ʻenehana kiʻekiʻe e pili ana, nā mea kiʻekiʻe a me ka nui o ka manawa e hoʻopau ai i ke kaʻina hana, no laila he kiʻekiʻe kona kumukūʻai. ʻO ka lua, no ka mea, ua hoʻokumu ʻia ka silicified carbon coating ma luna o ka ʻili o ka mea ma ke ʻano o ka hopena kemika, ua maʻalahi kona mānoanoa a me ke ʻano kiʻiʻoniʻoni e nā mea he nui e like me ke kaʻina hana, nā mea hoʻohālike a me ka nui, i hiki ʻole ke hoʻololi kekahi mau kūlana kūikawā.
I ka hōʻuluʻulu ʻana, ʻo ka uhi silicon carbide kekahi o nā hana kiʻekiʻe a me nā ʻāpana hana nui. Loaʻa iā ia nā pōmaikaʻi o ka pale ʻana i ka ʻaʻahu, ka pale ʻana i ka corrosion, ka paʻakikī kiʻekiʻe, ka pale ʻana i ka oxidation, ka adhesion ikaika a me nā ʻano ʻē aʻe, akā i ka manawa like, aia ke kumu kūʻai kiʻekiʻe, ka mānoanoa kiʻi ʻole a me nā hemahema ʻē aʻe. Eia nō naʻe, ke hoʻohālikelike ʻia me ka uhi kuʻuna, ua holomua nui ka uhi ʻana o ka silicon carbide a ua hoʻonui mālie ʻia kāna noi noi. Me ka hoʻomau mau ʻana a me ka hana hou o ka ʻenehana, manaʻoʻiʻo ʻia e hoʻohana ʻia ka silicon carbide coating i nā kula hou aʻe a hoʻonui i nā pono a me ka waiwai no nā kānaka.
