Ebumnuche bụ isi nke ọgwụgwọ elu nke akụkụ metallurgy ntụ ntụ:
1. Meziwanye ihe mgbochi iyi
2. Meziwanye nguzogide corrosion
3. Meziwanye ike ike ọgwụgwụ

Usoro ọgwụgwọ elu etinyere na akụkụ metallurgy ntụ ntụ nwere ike kewaa n'ụzọ ise ndị a:
1. mkpuchi: Na-ekpuchi elu nke akụkụ ahụ edoziri na oyi akwa nke ihe ndị ọzọ na-enweghị mmeghachi omume kemịkal ọ bụla
2. Ngwọta kemịkalụ dị n'elu: mmeghachi omume kemịkalụ dị n'etiti elu nke akụkụ a na-emezi yana mmeghachi omume mpụga
3. Usoro ọgwụgwọ okpomọkụ: ihe ndị ọzọ dị ka C na N na-agbasa n'elu akụkụ nke edoziri
4. Ngwọta okpomọkụ dị n'elu: a na-emepụta mgbanwe nke oge site na mgbanwe cyclic nke okpomọkụ, nke na-agbanwe microstructure nke elu nke akụkụ ahụ edoziri.
5. Mechanical deformation method: iji mepụta nrụrụ n'ibu n'elu akụkụ a na-ahazi, tumadi iji mepụta nrụgide fọdụrụnụ nke mkpakọ, ma na-abawanye njupụta elu.

ⅠMkpuchi
Electroplating nwere ike tinye na ntụ ntụ metallurgy akụkụ, ma ọ nwere ike na-rụrụ mgbe ntụ ntụ metallurgy akụkụ pretreated (dị ka itinye ọla kọpa ma ọ bụ itinye wax ka akara oghere) iji gbochie penetration nke electrolyte.Mgbe ọgwụgwọ electroplating gasịrị, enwere ike imeziwanye nguzogide corrosion nke akụkụ ahụ.Ihe atụ ndị a na-ahụkarị bụ galvanizing (iji chromate eme ihe maka passivation mgbe galvanizing iji nweta elu ojii ma ọ bụ ndị agha na-egbuke egbuke) na nickel plating.
Igwe nickel na-enweghị eletrọnị dị elu karịa nickel plating electrolytic n'akụkụ ụfọdụ, dị ka ịchịkwa ọkpụrụkpụ mkpuchi na ịrụ ọrụ nke ọma.
Usoro mkpuchi zinc "akọrọ" adịghị mkpa ka eme ya ma ọ dịghị mkpa ka a mechie ya.Ọ na-ekewa n'ime ntụ ntụ galvanizing na n'ibu galvanizing.
Mgbe a na-achọ mgbochi nchara, mgbochi corrosion, ọdịdị mara mma na mkpuchi eletriki, enwere ike iji eserese mee ihe.Enwere ike kewaa ụzọ ndị a: mkpuchi plastik, glazing, na ịgba ígwè.

Ⅱ.Ngwọta kemịkalụ elu

Ngwọta uzuoku bụ ihe a na-ahụkarị na usoro ọgwụgwọ elu maka akụkụ metallurgy ntụ ntụ.Ngwọta uzuoku bụ ikpocha akụkụ ahụ ruo 530-550C n'ime ikuku uzuoku iji mepụta oyi akwa magnetik (Fe3O4).Site oxidation nke elu nke ígwè matrix, na-eyi ndị na-eguzogide na esemokwu Njirimara na-mma, na akụkụ ndị na-eguzogide ọgwụ nchara arụmọrụ (na-esiwanye ike site mmanụ immersion) The oxide oyi akwa bụ banyere 0.001-0.005mm oké, na-ekpuchi dum elu elu elu. , ma nwee ike gbasaa n'etiti akụkụ ahụ site na pores jikọtara ọnụ.Ndochi nke pore a na-eme ka ike siri ike pụta ìhè, si otú ahụ kwalite nkwụsi ike na-eyi ma mee ka ọ nwee ogo dị elu nke nchịkọta.

Ngwọta phosphate oyi bụ mmeghachi omume kemịkalụ n'ime mmiri ịsa nnu iji mepụta phosphate dị mgbagwoju anya n'elu ihe ahụ.A na-eji Zinc phosphate mee ihe maka nhazi nke mkpuchi na mkpuchi plastik, a na-ejikwa manganese phosphate maka ngwa esemokwu.

A na-eme bluing ahụ site n'itinye workpiece na bath potassium chlorate na 150 Celsius site na corrosion kemịkalụ.Elu nke workpiece nwere agba anụnụ anụnụ.Ọkpụrụkpụ nke oyi akwa bluing bụ ihe dịka 0.001mm.Mgbe bluing gasịrị, elu akụkụ ahụ mara mma ma nwee ọrụ mgbochi nchara.

Nitriding agba agba na-eji mmiri nitrogen dị ka oxidant.N'oge usoro jụrụ oyi nke workpiece mgbe sintering, oxide oyi akwa na-etolite na okpomọkụ nso nke 200-550C.Agba nke oyi akwa oxide kpụrụ na-agbanwe na okpomọkụ nhazi.

A na-eji ọgwụgwọ mgbochi corrosion anodized eme ihe maka akụkụ aluminom iji meziwanye ọdịdị ya na arụ ọrụ mgbochi corrosion.

A na-etinye ọgwụgwọ passivation na akụkụ igwe anaghị agba nchara, tumadi iji mepụta oyi akwa mkpuchi oxide.Enwere ike ịmepụta oxides ndị a site na ikpo ọkụ ma ọ bụ ụzọ kemịkalụ, ya bụ, itinye nitric acid ma ọ bụ sodium chlorate ngwọta.Iji gbochie ihe ngwọta site na imikpu, kemịkalụ Usoro ahụ chọrọ ọgwụgwọ wax ka a na-ekpuchi tupu ya.
