Electroplating bụ usoro nke a na-esi na electrolyte na-agbapụta ígwè site n'omume nke ugbu a etinyere ma tinye ya n'elu ihe ahụ iji nweta akwa mkpuchi ígwè.
Galvanized:
Zinc na-adị mfe imebi na acid, alkalis, na sulfides.Ihe oyi akwa zinc na-agafe agafe.Mgbe passivation na chromate ngwọta, ihe nkiri passivation e guzobere adịghị mfe iji ikuku mmiri na-emekọrịta ihe, na ikike mgbochi corrosion na-abawanye nke ukwuu.N'ikuku akọrọ, zinc kwụsiri ike na ọ dịghị mfe ịgbanwe agba.N'ime mmiri na ikuku iru mmiri, ọ na-emeghachi omume na ikuku oxygen ma ọ bụ carbon dioxide iji mepụta ihe nkiri oxide ma ọ bụ alkaline carbonic acid, nke nwere ike igbochi zinc ka ọ nọgide na-agbaze ma na-arụ ọrụ nchebe.

Ọla kọpa:
Ọla kọpa anaghị eguzosi ike n'ikuku, ma n'otu oge ahụ, ọ nwere ikike dị elu nke ọma na enweghị ike ichebe ọla ndị ọzọ site na corrosion.Otú ọ dị, ọla kọpa nwere elu eletriki conductivity, na ọla kọpa plating oyi akwa siri ike na ezi, ọ na-ike jikọtara ya na isi metal, na ọ nwere ezi polishing performance.It a na-ejikarị eme ka mma conductivity nke ihe ndị ọzọ, dị ka ala oyi akwa nke. electroplating ndị ọzọ, dị ka ihe mkpuchi nchebe iji gbochie carburization, na iji belata esemokwu ma ọ bụ ihe ịchọ mma na nkedo.
Ọdabara ihe: nwa metal, ọla kọpa na ọla kọpa alloy nickel-plated, chrome-plated ala oyi akwa.
Ngwakọta nickel:
Nickel nwere ezigbo nkwụsi ike nke kemịkalụ na ikuku na lye, ọ dịghịkwa mfe ịgbanwe agba, mana ọ na-adị mfe soluble na nitric acid.Ọ dị mfe ịfefe na nitric acid gbadoro ụkwụ, na ọghọm ya bụ porosity.Iji merie mwepu a, enwere ike iji plating metal multi-layer, na nickel bụ oyi akwa etiti.Ngwurugwu nickel plating nwere ike dị elu, ọ dị mfe ịmegharị, nwere nnukwu ọkụ ọkụ na-egbuke egbuke ma nwee ike ịbawanye ọdịdị na nguzogide, ma nwee ezigbo nguzogide corrosion.

Tin platting:
Tin nwere nnukwu nkwụsi ike kemịkalụ.Ọ dịghị mfe igbari na itule ngwọta nke sulfuric acid, nitric acid na hydrochloric acid.Sulfides enweghị mmetụta na tin.Tin kwụsiri ike na organic acid, na ogige ya anaghị egbu egbu.A na-ejikarị ya na igbe ụlọ ọrụ nri na akụkụ nke ụgbọ elu, igodo na akụrụngwa redio.Enwere ike iji ya gbochie wires ọla kọpa ka sọlfọ na rọba na-emetụta ya na dịka ihe mkpuchi maka ebe ndị na-abụghị nitriding.
