ʻO nā ʻāpana seramika SiC ʻoihana kūʻai kūʻokoʻa i ka lole a me ka wela kiʻekiʻe

ʻO ke kūpaʻa wela o ka silika carbide seramika

ʻO ka silikoni carbide ceramics (SiC ceramics) he ʻano hou o nā mea seramika me ka paʻakikī kiʻekiʻe, ka ikaika kiʻekiʻe a me ke kūpaʻa lole kiʻekiʻe. ʻO kāna mea nui ʻo ka silicon carbide, a ʻo kona ʻano aniani he kiʻekiʻe kiʻekiʻe ka wela a me ka paʻa kemika. Hōʻike nā hoʻokolohua e hiki i ka silicon carbide ceramics ke mālama i ka hana paʻa ma lalo o ke kaiapuni wela kiʻekiʻe, a ʻoi aku ka maikaʻi o kona pale ʻana i ka wela ma mua o nā mea seramika kahiko.

Wahi a ka noiʻi, hiki ke piʻi aku ka pale wela o ka silicon carbide ceramics ma mua o 2000 degere Celsius. I kēlā ʻano wela kiʻekiʻe, mālama mau ka silicon carbide ceramics i nā waiwai mechanical maikaʻi a me ka paʻa o ke kūkulu ʻana, kahi e loaʻa ai iā ia kahi ākea o nā noi noi ma ke kaiapuni kiʻekiʻe.

ʻO ka manaʻolana no ka hoʻohana ʻana i nā seramika silika carbide

1. Aerospace

I loko o ka ʻoihana aerospace, ʻaʻole hiki ke pale ʻia nā wahi wela kiʻekiʻe. ʻO ke kūpaʻa wela kiʻekiʻe o ka silicon carbide ceramics e lilo ia i mea koho kūpono no nā ʻāpana wela kiʻekiʻe e like me nā ʻenekini mokulele a me nā pahu pahu.

2. 'Oihana ikehu a me kemika

Ma ke kahua o ka ikehu a me ka ʻoihana kemika, kiʻekiʻe kiʻekiʻe wela reactors a me ka wela exchangers a me nā mea hana 'ē aʻe i kiʻekiʻe koi no ka wela o na mea. ʻO ke kūpaʻa wela kiʻekiʻe o ka silicon carbide ceramics e lilo ia i mea koho no kēia mau mea hana

3. Mekini hana

Ma ke kahua o ka mīkini ʻenehana, hiki i ke kūpaʻa wela kiʻekiʻe o ka silicon carbide ceramics ke hoʻomaikaʻi i ka pale ʻana o ka lole a me ke kūpaʻa corrosion o nā mea mīkini a hoʻonui i ke ola lawelawe o nā mea hana.

Loaʻa i nā seramika Silicon carbide nā manaʻo noi ākea ma muli o ko lākou kūlana kiʻekiʻe kiʻekiʻe. Me ka hoʻomau mau ʻana o ka ʻepekema a me ka ʻenehana, ua manaʻo ʻia e ʻoi aku ka nui o ke kahua noi o ka silicon carbide ceramics, e lawe mai i ka ʻoluʻolu a me ka holomua i ke kaiāulu kanaka.
