N'ụlọ ọrụ electroplating, electroplating ike pulse adọtala uche n'ihi arụmọrụ mkpuchi ya dị elu. Ma e jiri ya tụnyere electroplating DC ọdịnala, ọ nwere ike inweta mkpuchi nwere kristal dị mma, nke yiri nke ọma, na nke dị elu. N'ezie, electroplating pulse adabaghị maka ọnọdụ niile, o nwere oke ojiji nke ya.
Ya mere, kedu ihe bụ isi eji eme ihe na electroplating pulse? Nke a na-amalite site na ọtụtụ uru pụrụ iche ya.
1. Mkpọchi mkpuchi ahụ ka mma karịa
N'oge mmegharị pulse, oke ọkụ eletrik nwere ike iru ọtụtụ ugboro ma ọ bụ karịa ugboro iri nke ọkụ eletrik DC. Oke ọkụ eletrik dị elu na-eduga na oke ike dị elu, na-amụba nke ukwuu ọnụọgụ atọm ndị a na-etinye n'elu cathode. Ọnụego nucleation dị ngwa karịa ọnụego uto kristal, na-eme ka mkpuchi kristal dị mma. Ụdị mkpuchi a nwere nnukwu njupụta, ike dị elu, obere oghere, yana iguzogide nchara ka mma, iguzogide iyi, ịgbado ọkụ, njikwa ike, na ihe ndị ọzọ. Ya mere, a na-ejikarị electroplating pulse eme ihe n'ọhịa electroplating arụ ọrụ nke chọrọ arụmọrụ dị elu.
2. Ike mgbasa ka mma
Ọkụ eletrik nwere ikike mgbasa ozi dị mma, nke dị mkpa karịsịa maka ụfọdụ ihe ịchọ mma electroplating. Dịka ọmụmaatụ, mgbe ejiri ọla edo ma ọ bụ ọlaọcha mee ihe mkpuchi buru ibu, pulse electroplating nwere ike ime ka agba ahụ yie otu ma mee ka àgwà ya kwụsie ike. Ka ọ dịgodị, n'ihi mgbakwunye nke usoro njikwa mpụga, ịdabere na mma mkpuchi na ngwọta ịsa ahụ na-ebelata, njikwa ọrụ dịkwa mfe karị. Ya mere, n'ọnọdụ ụfọdụ ihe ịchọ mma electroplating dị elu, pulse electroplating ka nwere uru ya. N'ezie, maka electroplating mma nchebe ọdịnala, dị ka igwe kwụ otu ebe, ihe njide, wdg, ọ dịghị mkpa iji ya.
3. Ịdị ọcha dị elu nke mkpuchi
N'oge mmịpụta ahụ, ụfọdụ usoro mmịpụta dị mma na-eme n'elu cathode, dị ka gas hydrogen a gwakọtara agwakọta ma ọ bụ ihe ndị na-adịghị ọcha na-ewepụ ma laghachi na ngwọta ahụ, si otú a na-ebelata mmịpụta hydrogen ma melite ịdị ọcha nke mkpuchi ahụ. Ịdị ọcha dị elu nke mkpuchi ahụ na-eme ka ọrụ ya ka mma. Dịka ọmụmaatụ, mmịpụta ọlaọcha pulse nwere ike ime ka ike ịgbado ọkụ, njikwa ike, iguzogide agba, na ihe ndị ọzọ dịkwuo mma, ma nwee uru dị mkpa na agha, eletrọnịkị, ụgbọelu, na mpaghara ndị ọzọ.
4. Ọsọ ọsọ nke sedimentation
Ụfọdụ ndị nwere ike iche na pulse electroplating nwere obere ọnụego itinye ihe karịa kpọmkwem electroplating eletrik n'ihi ọnụnọ nke oge gbanyụọ. N'ezie, ọ bụghị otú ahụ. Ọnụego sedimentation dabere na ngwaahịa nke njupụta ugbu a na arụmọrụ ugbu a. N'okpuru nkezi njupụta ugbu a yiri nke ahụ, pulse electroplating na-agbakọ ngwa ngwa n'ihi mgbake nke mkpokọta ion na mpaghara cathode n'oge njedebe, na-ebute arụmọrụ ugbu a dị elu. Enwere ike iji atụmatụ a na mmepụta electroplating na-aga n'ihu nke chọrọ nkwụnye ngwa ngwa, dị ka waya eletrọniki.
N'ezie, na mgbakwunye na ngwa ndị a kpọtụrụ aha n'elu, site na ọganihu teknụzụ, ihe ndị na-enye ike pulse na-agbasakwa ngwa ha mgbe niile n'ọhịa dịka nanoelectrodeposition, anodizing, na mgbake electrolytic. Maka electroplating nkịtị, ịgbanwe gaa na pulse electroplating naanị iji melite arụmọrụ mmepụta nwere ike ọ gaghị adị ọnụ ala.
