Hāʻawi kā mākou huiKa uhi ʻana o SiCkaʻina hana ma ke ʻano CVD ma ka ʻili o ka graphite, ceramics a me nā mea ʻē aʻe, no laila e hana nā kinoea kūikawā i loaʻa i ke kalapona a me ke silikoni i ka wela kiʻekiʻe e loaʻa ai nā molekala SiC maʻemaʻe kiʻekiʻe, nā molekala i waiho ʻia ma ka ʻili o nā mea i uhi ʻia, e hana ana i kahiSiC pale pale.
Nā hiʻohiʻona nui
1. Kiʻekiʻe wela oxidation kū'ē:
ʻoi aku ka maikaʻi o ka pale ʻana i ka oxidation ke kiʻekiʻe ka mahana e like me 1600 C.
2. Maʻemaʻe kiʻekiʻe: hana ʻia e ka hoʻoheheʻe ʻana i ka mahu ma lalo o ke kūlana chlorination kiʻekiʻe.
3. Erosion kū'ē: kiʻekiʻe paakiki, paʻaʻiliʻili, maikaʻi particles.
4. Ke kū'ē i ka corrosion: acid, alkali, paʻakai a me nā mea hoʻoulu.
