ʻO ka hale hana ʻāpana seramika SiC ʻoihana maʻamau e kū i ka ʻaʻahu a me ke kiʻekiʻe o ka mahana

Ke kūpaʻa mahana o nā keramika silicon carbide

ʻO nā keramika silikona carbide (SiC keramika) kahi ʻano mea keramika hou me ka paʻakikī kiʻekiʻe, ka ikaika kiʻekiʻe a me ke kūpaʻa kiʻekiʻe o ka ʻaʻahu. ʻO kona ʻāpana nui ka silicon carbide, a he kiʻekiʻe loa ke kūpaʻa wela a me ke kemika o kona ʻano kristal. Hōʻike nā hoʻokolohua e hiki i nā keramika silikona carbide ke mālama i ka hana paʻa ma lalo o ke kaiapuni wela kiʻekiʻe loa, a ʻoi aku ka maikaʻi o kona kūpaʻa wela ma mua o nā mea keramika kuʻuna.

Wahi a ka noiʻi, hiki i ke kūpaʻa wela o nā keramika silicon carbide ke piʻi ma mua o 2000 degere Celsius. Ma ia ʻano wela kiʻekiʻe, mālama mau nā keramika silicon carbide i nā waiwai mechanical maikaʻi a me ke kūpaʻa kūkulu, kahi e loaʻa ai iā ia kahi ākea ākea o nā manaʻolana noi i ke kaiapuni wela kiʻekiʻe.

Ka manaʻolana no ka hoʻohana ʻana i nā keramika silicon carbide

1. Lewa

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

2. ʻOihana ikehu a me ke kemika

Ma ke kahua o ka ikehu a me ka ʻoihana kemika, loaʻa i nā reactors wela kiʻekiʻe a me nā mea hoʻololi wela a me nā lako ʻē aʻe nā koi kiʻekiʻe no ke kūpaʻa wela o nā mea. ʻO ke kūpaʻa wela kiʻekiʻe o nā keramika silicon carbide e lilo ia i mea koho no kēia mau mea hana.

3. Nā mīkini ʻoihana

Ma ke kahua o nā mīkini ʻoihana, hiki i ke kūpaʻa kiʻekiʻe o ka mahana o nā keramika silicon carbide ke hoʻomaikaʻi i ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa i ka pala o nā lako mīkini a hoʻolōʻihi i ke ola lawelawe o nā lako.

He ākea nā manaʻolana no ka hoʻohana ʻana o nā keramika silikona carbide ma muli o ko lākou kūpaʻa maikaʻi loa i ka mahana kiʻekiʻe. Me ka hoʻomohala mau ʻana o ka ʻepekema a me ka ʻenehana, ua manaʻoʻiʻo ʻia e ʻoi aku ka laulā o ke kahua noi o nā keramika silikona carbide, e lawe mai ana i ka ʻoluʻolu a me ka holomua i ke kaiāulu kanaka.
