Kedu ihe bụ Dehydrogen Annealing?

Dehydrogen annealing bụ ausoro ọgwụgwọ okpomọkụrụrụ iji wepụagbazere hydrogensitere na akụrụngwa arụrụ arụ. Enwere ike ịmepụta hydrogen n'oge:

• pickling (acid ihicha)

• Electrorating

• ịgbado ọkụ

• Ịmepụta n'ime ikuku ikuku ma ọ bụ mmiri nwere hydrogen

Ọ bụrụ na ewepụghị ya, atom hydrogen nwere ike ịkpatahydrogen-akpata cracking(HIC), mgbawa egbu oge, ma ọ bụọnwụ nke n'ibu iguzosi ike n'ezi ihe.

Kedu ihe kpatara Dehydrogen Annealing ji dị mkpa?

Usoro a dị oke mkpa maka ọtụtụ ihe kpatara ya:

• Na-egbochi ọdịda hydrogen embrittlement

Ihe Na-achọ Dehydrogen Annealing

A na-etinyekarị dehydrogen annealing na ihe ndị a adịgboroja:

• Carbon ígwè(karịsịa agbanyụọ na iwe)

• Alloy ígwè(dịka ọmụmaatụ, 4140, 4340, 1.6582)

• Martensitic igwe anaghị agba nchara( ọmụmaatụ, 410, 420)

• Austenitic igwe anaghị agba nchara(dịka ọmụmaatụ, 304, 316 - mgbe a kpochara ma ọ bụ efere)

• Titanium na titanium alloys

• Alloys dabeere na nickel(na gburugburu ikuku hydrogen)

Akpụkpọ anụ ekpughere na ihicha acidic, mmeghachi omume electrochemical, ma ọ bụ ikuku nwere hydrogen bụ ndị isi na-akwado maka ọgwụgwọ a.
