Hōʻike huahana
Hāʻawi kā mākou hui i nā lawelawe kaʻina hana hoʻoheheʻe SiC ma ke ʻano CVD ma ka ʻili o ka graphite, ceramics a me nā mea ʻē aʻe, i hiki ai i nā kinoea kūikawā i loaʻa ke kalapona a me ke silika i ke kiʻekiʻe kiʻekiʻe e loaʻa ai nā molekala SiC maʻemaʻe kiʻekiʻe. e hana ana i ka papa pale SIC.
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.
