Mmepụta nke calcium aluminom alloy bụ usoro ịgbaze na fusing na ọnọdụ oghere na-eji okpomọkụ dị elu dịka akụkụ ụfọdụ nke calcium metal na aluminum metal si dị.
Nkewa nke Calcium Aluminom Alloy:
Calcium aluminum alloy bụ nkewa n'ozuzu 70-75% calcium, 25-30% aluminum; 80-85% calcium, 15-20% aluminum; na 70-75% calcium 25-30%. Enwere ike ịhazi ya dịka achọrọ. Calcium aluminom alloy nwere ọla ọla, ọdịdị dị ndụ, na ezigbo ntụ ntụ dị mfe ọkụ na ikuku. A na-ejikarị ya dị ka nnukwu alloy, nnụcha na mbenata gị n'ụlọnga na-agbaze ọla. The ngwaahịa na-ọnọ n'ụdị eke blocks, na nwekwara ike-esichara n'ime ngwaahịa nke dị iche iche urughuru nha dị ka onye ọrụ mkpa.
Nhazi Ogo nke
Dị ka nnukwu alloy, àgwà chọrọ maka calcium aluminom alloy bụ nke siri ike. (1) Ọdịnaya nke calcium ọla na-agbanwe na obere nso; (2) Alloy agaghị enwe nkewa; (3) A ghaghị ịchịkwa ihe adịghị ọcha na-emerụ ahụ n'ime oke ezi uche dị na ya; (4) Agaghị enwe oxidation n'elu alloy; N'otu oge ahụ, a chọrọ mmepụta, nkwakọ ngwaahịa, njem na nchekwa nke calcium aluminum alloy A ghaghị ịhazi usoro ahụ nke ọma. Na ndị na-emepụta calcium-aluminom alloys anyị na-enye ga-enwerịrị iru eru.
Ụgbọ njem na nchekwa
Njirimara chemical nke calcium aluminum alloy na-arụsi ọrụ ike. Ọ dị mfe oxidize na ọkụ ngwa ngwa mgbe ọkụ, mmiri na mmetụta siri ike.
1. Nkwakọ ngwaahịa
Mgbe calcium aluminom alloy gwepịara dị ka ụfọdụ nkọwa, a na-etinye ya na akpa rọba, tụọ ya, juputara na gas argon, kpochie ọkụ, wee tinye ya n'ime ụgbọ mmiri ígwè (mba ọkọlọtọ mba ụwa). gbọmgbọm ígwè ahụ nwere ezigbo mgbochi mmiri, ikuku dịpụrụ adịpụ na ọrụ mgbochi.
2. Nbudata na ibutu
