Silicon carbide ceramics: ʻO kekahi o nā mea hana seramika pale pōkā kaulana loa

ʻO ka paʻa koʻikoʻi Silicon carbide covalent ikaika loa, aia nō ka ikaika kiʻekiʻe o ka hoʻopaʻa ʻana i ka wela kiʻekiʻe, hāʻawi kēia ʻano hana i ka silicon carbide ceramics i ka ikaika maikaʻi loa, kiʻekiʻe paʻakikī, ʻaʻahu kūʻokoʻa, corrosion resistance, high thermal conductivity, thermal shock resistance a me nā waiwai ʻē aʻe; I ka manawa like, ʻo ke kumukūʻai o ka silicon carbide ceramics he haʻahaʻa, kumu kūʻai, ʻo ia ka mea i hoʻohana nui ʻia i nā ceramics bulletproof ma Kina, akā ʻo kekahi o ka hoʻomohala ʻana i nā mea pale pale pale kiʻekiʻe.

ʻO ka hana maikaʻi loa o ka mea silicon carbide hiki ke hoʻomaikaʻi i ke kūʻē o ka mea pale. ʻO ka silikon carbide keramika ponoʻī ka ikaika kiʻekiʻe, kiʻekiʻe paʻakikī, kiʻekiʻe ka pale ʻana i ka lole, ka hana ballistic maikaʻi loa (ʻoi aku ka maikaʻi ma mua o ka alumina ceramics, e pili ana i 70% -80% o ka boron carbide ceramics), ke kumu kūʻai haʻahaʻa a me nā ʻano ʻē aʻe he kūpono loa no ka noi ʻana i ka pōkā. mea hana. Hoʻohana pinepine ʻia i loko o ka ʻoihana kaua pahu pahu, ka mea kaua moku, ka mea pale kaʻa a me nā mea pale ʻē aʻe; Hoʻohana pinepine ʻia ka ʻoihana kīwila e like me nā mea pale pale kaʻa, nā mea palekana palekana, etc.

Loaʻa i ka ʻenehana silikon carbide nā waiwai mechanical, thermal, kemikala a me ke kino, a he ākea ākea ākea ma ke kahua o ka pale kaua. I kēia mau makahiki i hala iho nei, ua hoʻohana nui ʻia nā mea pale kila silicon carbide ceramic bulletproof ma ke kahua o ka pale kaua, e like me nā lako pilikino, pūʻali koa mea kaua kahua kaua, gunship a me nā mākaʻi, nā kaʻa kūikawā kīwila. Eia kekahi, ke hoʻonui nei ka hoʻohana ʻana o ka silicon carbide i semiconductor, ka ikehu nuklea a me nā ʻenehana kiʻekiʻe ʻē aʻe, ākea loa ka manaʻo noi.
