ʻO kaKa uhi ʻana o CVD SiCʻO CC Composite Rod,ʻO ke koʻokoʻo hoʻohuihui kalapona kalapona silika, SiC Coated CC Composite Rod mai vet-china e hui pu i na waiwai okoa okalapona kalapona (CC) compositesme kahi paleKa uhi ʻana o CVD SiC (Silicon Carbide).. Hoʻolālā ʻia kēia koʻokoʻo kiʻekiʻe no nā noi hana kiʻekiʻe e koi ana i ke kūpaʻa wela ʻoi aku ka maikaʻi, ka ikaika mechanical, a me ke kūpaʻa kemika. Hāʻawi ka carbon-carbon core i ka lōʻihi maikaʻi a me nā waiwai māmā, aʻo ka uhi SiC e hoʻonui i ka pale ʻana i ka ʻaʻahu, oxidation, a me nā wela kiʻekiʻe.
Hāʻawi ka CVD SiC coating i ka pale paʻa, e ʻae i ke koʻokoʻo e kū i nā kūlana koʻikoʻi, i mea kūpono no ka hana semiconductor, aerospace, a me nā kaʻina hana. vet-china hōʻoia i kaKa uhi ʻana o CVD SiCHiki i ka CC Composite Rod ke mālama i nā mahana ma mua o 1600 ° C, e hāʻawi ana i ka hilinaʻi i nā kaiapuni e koi ana i ka pololei a me ka lōʻihi.
Hoʻolālā ʻia ka lāʻau vet-china composite e hana i nā kūlana paʻakikī loa, e hōʻoiaʻiʻo ana i ka paʻa a me ka hoʻonui ʻana i ke ola o nā ʻāpana i nā ʻoihana kiʻekiʻe. ʻO ka hui pū ʻana o ka CVD SiC coating a me ka CC composite structure ka hopena i kahi huahana ʻaʻole māmā wale nō akā ikaika loa a kūpaʻa i ka lole a me ka waimaka.
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.
