Okwu Mmalite nke semiconductor-ọkwa enyo mkpuchi carbon

I. Okwu mmalite nke enyo Ọdịdị carbon

Njirimara:

(1) N'elu nke ugogbe anya carbon dị nro ma nwee nhazi enyo;

(2) Glassy carbon nwere nnukwu ike ike na obere uzuzu ọgbọ;

(3) Glassy carbon nwere ọnụ ahịa ID / IG buru ibu na ọkwa dị ala nke graphitization, yana arụmọrụ mkpuchi ọkụ ya ka mma;

(4) Glassy carbon bụ carbon siri ike-graphitize nke nwere ezigbo nkwụsi ike dị elu na nkwụsi ike na okpomọkụ dị elu;

(5) Glassy carbon nwere obere mmeghachi omume dị n'elu ebe yana ezigbo nguzogide corrosion kemịkalụ, ma na-eguzogide oke ikuku site na oxygen, silicon, wdg.

II. Okwu mmalite nke mkpuchi carbon enyo

A na-ekesa oghere dị n'elu nke mkpuchi graphite flake na ihe owuwu ahụ tọgbọrọ chakoo, ebe nhazi nke mkpuchi carbon enyo siri ike ma ghara ịdaba!

1. Anti-oxidation arụmọrụ nke glassy carbon mkpuchi

(1)Laminated ike chere
Glassy carbon mkpuchi n'ụzọ dị irè na-eme ka mgbochi oxidation arụmọrụ nke ike mmetụta;

(2)Short eriri ike chere

The n'ozuzu mmetụta nwere a elu porosity na-enye oxygen ọwa; mkpuchi flake graphite nwere usoro rụrụ arụ, ọwa ikuku oxygen dị ole na ole, yana arụmọrụ mgbochi oxidation ka mma; mkpuchi carbon nke enyo enyo nwere nnukwu usoro, ọwa ikuku oxygen dị ole na ole, yana arụmọrụ mgbochi kacha mma.

2. Nkwụsi ike dị elu nke mkpuchi carbon enyo megide ablation

Ọdịdị porous nke larịị chere nwere ike belata okpomọkụ (okpomọkụ convection okpomọkụ dissipation); akwụkwọ graphite na-enwekarị ọnya ọnya mgbe a na-ewepụ ya; ihe omimi nke ablation nke mkpuchi carbon enyo bụ nke kachasị njọ, na nkwụsị nkwụsị ya bụ nke kachasị ike; mkpuchi carbon nke enyo nwere ezigbo mkpuchi mkpuchi ọkụ.

3. Anti-Si ozision arụmọrụ nke glassy carbon mkpuchi

Mkpirisi eriri ike chere na-emebi emebi na powdered site Si; flake graphite mkpuchi nwere iguzogide Si ozize na obere oge; mkpuchi carbon enyo enyo nwere arụmọrụ mgbochi ikuku kacha mma.

Isi ihe kpatara Si erosion bụ na Si gasification ozugbo na-emebi elu nke ike chere, na-akpata powderization; ebe usoro carbon nke mkpuchi carbon glassy na-akwụsi ike ma nwee arụmọrụ mgbochi ikuku ka mma.

Nchịkọta

A naghị eji usoro mkpuchi carbon carbon enyo naanị na ihe mkpuchi ọkụ, mana a na-atụkwa anya na a ga-eji ya ozugbo n'elu akụkụ graphite naAkụkụ C/C, na-emeziwanye arụmọrụ ọrụ zuru oke nke ihe ahụ.
