  • Kedu usoro CVD maka diamond?

Usoro mgbanye mmiri kemịkalụ (CVD) nke diamond gụnyere iji usoro kemịkalụ iji mepụta ihe nkiri diamond ma ọ bụ mkpuchi na gburugburu ebe a na-achịkwa. Na usoro a, a na-ewebata ngwakọta gas, nke na-enwekarị gas hydrocarbon dị ka methane, n'ime ụlọ mmeghachi omume yana ihe ndị dị ka molybdenum wafers ma ọ bụ diamond wafers. A na-eji ụzọ dị iche iche arụ ọrụ gas, dị ka okpomoku ma ọ bụ plasma, iji kwatuo molekul hydrocarbon ma tinye carbon carbon na mkpụrụ, na-ebute kristal diamond toto.

Usoro CVD nke diamond na-enye ọtụtụ uru, gụnyere ikike ịmepụta ihe mkpuchi diamond dị elu na njikwa ziri ezi nke ọkpụrụkpụ, otu na nhazi. Ọ na-enyekwa ohere itinye ihe nkiri diamond na ihe dị iche iche nke mkpụrụ osisi, na-eme ka ịmepụta akụkụ ndị nwere diamond maka ọtụtụ ụlọ ọrụ mmepụta ihe na nyocha.

N'ozuzu, usoro CVD nke diamond bụ usoro dị iche iche na nke a na-ejikarị eme ihe maka ịmepụta ihe nkiri diamond synthetic na mkpuchi nwere ihe ndị ahaziri ahazi, na-eme ka ha baa uru na ụlọ ọrụ dịka ngwá ọrụ eletriki, ngwá ọrụ ịkpụ, na mkpuchi na-eguzogide.

  • Kedu ihe siri ike nke mkpuchi CVD?

Isi ike nke mkpuchi vapor deposition (CVD) nwere ike ịdịgasị iche dabere na ihe ndị akọwapụtara na usoro ejiri. Agbanyeghị, mkpuchi CVD mara maka ike siri ike ha pụrụ iche, na-adịkarị karịa nke mkpuchi mkpuchi anụ ahụ nkịtị (PVD).

Maka mkpuchi CVD diamond, ike siri ike bụ ihe kwesịrị ịrịba ama. Diamond bụ otu n'ime ihe ndị siri ike mara, na mkpuchi diamond CVD nwere ike siri ike nke na-adịkarị karịa nke ụdị mkpuchi ndị ọzọ. A na-atụkarị ike nke mkpuchi diamond CVD site na iji akara siri ike nke Vickers na sitere na 8000 HV ruo n'elu 10000 HV, na-eme ka ọ bụrụ otu n'ime ihe ndị siri ike na nke na-eguzogide ọgwụ.

Maka mkpuchi CVD ndị ọzọ, dị ka mkpuchi nke carbide ma ọ bụ nitride, ike siri ike nwekwara ike ịdị elu, na-enye nkwụsi ike dị mma na ịdịte aka n'ọtụtụ ngwa ọrụ mmepụta ihe.

N'ozuzu, a na-eji mkpuchi CVD kpọrọ ihe maka ike siri ike ha pụrụ iche, na-eme ka ọ dị mma maka ngwa ndị na-eyi nkwụsi ike, nkwụsi ike dị elu, na ịrụ ọrụ ogologo oge dị oke egwu.
