ʻO ka hana maikaʻi loa o ka moku aniani carbide silika ma ke kaiapuni wela

ʻO ka waʻa kristal kalapona silikaHe mea ia me nā waiwai maikaʻi loa, e hōʻike ana i ka wela a me ka pale ʻana i ka corrosion ma nā wahi wela kiʻekiʻe.He hui ia me nā mea kalapona a me ke silika me ka paʻakikī kiʻekiʻe, ka helu heheʻe kiʻekiʻe a me ka conductivity thermal maikaʻi loa.ʻO kēia ka mea i kūpono i nā waʻa kristal carbide silicon no nā ʻano noi wela kiʻekiʻe, e like me ka aerospace, ka ikehu nuklea, kemika, etc.

ʻO ka mea mua, kawaapa kalapona kalaponaloaʻa i ka wela maikaʻi ma nā wahi wela kiʻekiʻe.Ma muli o kona hoʻolālā aniani kūikawā, kawaapa kalapona kalaponahiki iā ia ke mālama i kona mau waiwai kino a me kemika ma lalo o nā kūlana wela loa.Hiki iā ia ke pale i nā mahana a hiki i ka 1500 degrees Celsius me ka ʻole o ka deformation a i ʻole rupture, e hoʻohana nui ʻia i ka hoʻoheheʻe wela kiʻekiʻe, ka hopena wela kiʻekiʻe a me nā kaʻina hana ʻē aʻe.

ʻO ka lua, ʻo kawaapa kalapona kalaponaloaʻa i ka corrosion kūpaʻa maikaʻi i ke kiʻekiʻe wela kaiapuni.I kekahi mau wahi kemika koʻikoʻi, nui nā metala a me nā mea ʻē aʻe e hoʻopilikia ʻia e ka corrosion, akā hiki i ka moku aniani carbide silicon ke mālama i kona kūpaʻa.ʻAʻole ia e ʻino ʻia e ka waikawa, alkali a me nā mea corrosive ʻē aʻe, e hoʻohana nui ʻia i nā kemika, uila a me nā ʻoihana ʻē aʻe.

Eia hou, ka thermal conductivity o kawaapa kalapona kalaponaʻo ia kekahi o kāna mau pono.Ma muli o kona ʻano ʻano aniani kū hoʻokahi, he kiʻekiʻe kiʻekiʻe ka hoʻoili ʻana o ka pahu silicon carbide crystal a hiki iā ia ke lawe koke i ka wela a mālama i ka hāʻawi ʻana o ka mahana.Hoʻohana nui kēia i ka mālama wela, ka hana semiconductor a me nā māla ʻē aʻe.

I ka pōkole,waapa kalapona kalaponame kona kūpaʻa wela maikaʻi loa, ka pale ʻana i ka corrosion a me ka conductivity thermal, e lilo i mea kūpono i ke ʻano wela wela.Loaʻa iā ia ka laulā o nā noi, hiki ke hoʻokō i nā pono o nā kaʻina hana wela kiʻekiʻe, a loaʻa ka mana nui i ka hoʻomohala e hiki mai ana.
