Embonini ye-electroplating, i-pulse power electroplating idonsele ukunaka ngenxa yokusebenza kwayo okuphezulu kokumboza. Uma kuqhathaniswa ne-DC electroplating yendabuko, ingathola ukumboza okunamakristalu acwebezelayo, afanayo, futhi acwebezelayo. Yiqiniso, i-pulse electroplating ayifaneleki kuzo zonke izimo, inobubanzi bayo bokusetshenziswa.
Ngakho-ke, yiziphi izinhlelo zokusebenza eziyinhloko ze-pulse electroplating? Lokhu kuqala ngezinzuzo zayo eziningana ezivelele.
1. Ukucwebezela kwesembozo kucwengisiswe kakhulu
Ngesikhathi sokuqhuba i-pulse, ugesi ophezulu ungafinyelela izikhathi eziningana noma ngisho nangaphezulu kwe-DC current. Ubuningi bamandla aphezulu buholela ekuqineni okuphezulu, okwandisa kakhulu inani lama-athomu afakwe ebusweni be-cathode. Izinga le-nucleation lishesha kakhulu kunezinga lokukhula kwe-crystal, okuholela ekuhlanganisweni okucwebezelayo kahle. Lolu hlobo lokufaka lunobukhulu obuphezulu, ubulukhuni obuphezulu, ama-pores ambalwa, kanye nokumelana nokugqwala okungcono, ukumelana nokuguguleka, ukushisela, ukuqhuba, nezinye izakhiwo. Ngakho-ke, i-pulse electroplating isetshenziswa kabanzi emikhakheni ye-electroplating esebenzayo edinga ukusebenza okuphezulu.
2. Ikhono elingcono lokuhlakazeka
Ukufakwa kwe-pulse electroplating kunekhono elihle lokusabalala, okubaluleke kakhulu kwezinye izingcezu zokuhlobisa ze-electroplating. Isibonelo, lapho ukufakwa kwegolide noma isiliva kufakwa izinto ezinkulu zokusebenza, ukufakwa kwe-pulse electroplating kungenza umbala ufane kakhulu futhi ikhwalithi izinze kakhudlwana. Okwamanje, ngenxa yokwengezwa kwendlela yokulawula yangaphandle, ukuncika kwekhwalithi yokumboza esixazululweni sokugeza kuyancishiswa, futhi ukulawula kokusebenza kulula kakhulu. Ngakho-ke, kwezinye izingcezu zokuhlobisa ze-electroplating ezifunwa kakhulu, ukufakwa kwe-pulse electroplating kusenenani lazo. Vele, nge-electroplating yokuhlobisa evamile, njengamabhayisikili, izinamathiseli, njll., akudingekile ukuyisebenzisa.
3. Ukuhlanzeka okuphezulu kokumboza
Ngesikhathi sokuphumula kwe-pulse, ezinye izinqubo ezinhle zokususa i-sorption zenzeka ebusweni be-cathode, njengegesi ye-hydrogen efakwe emanzini noma ukungcola okuphumayo bese kubuyela esixazululweni, ngaleyo ndlela kunciphisa ukuqhekeka kwe-hydrogen futhi kuthuthukise ubumsulwa be-coating. Ubumsulwa obuphezulu be-coating buthuthukisa ukusebenza kwayo. Isibonelo, i-pulse silver plating ingathuthukisa kakhulu ukushintshwa, ukuhanjiswa kwamandla, ukumelana nombala, nezinye izakhiwo, futhi inenani elibalulekile kwezempi, kuma-elekthronikhi, ezindiza, nakwamanye amasimu.
4. Izinga lokusheshisa kokuthungwa kwenhlabathi
Abanye abantu bangase bacabange ukuthi i-pulse electroplating inesilinganiso sokufakwa esiphansi kune-direct current electroplating ngenxa yokuba khona kwesikhathi sokuvala. Empeleni, akunjalo. Izinga lokuthuthwa kwendle lincike kumkhiqizo wobuningi bamanje kanye nokusebenza kahle kwamanje. Ngaphansi kobuningi bamanje obujwayelekile obufanayo, i-pulse electroplating ivame ukufaka ngokushesha ngenxa yokubuyiselwa kokuhlushwa kwe-ion esifundeni se-cathode ngesikhathi sokungasebenzi, okuholela ekusebenzeni kahle kwamanje okuphezulu. Lesi sici singasetshenziswa ekukhiqizweni okuqhubekayo kwe-electroplating okudinga ukufakwa okusheshayo, njengezintambo zikagesi.
Vele, ngaphezu kwezicelo ezishiwo ngenhla, ngentuthuko yezobuchwepheshe, izinsiza zikagesi ze-pulse nazo zandisa njalo izinhlelo zazo emikhakheni efana ne-nanoelectrodeposition, i-anodizing, kanye nokuvuselelwa kwe-electrolytic. Ngokufakelwa kwe-electrolytic okuvamile, ukushintshela ku-pulse electroplating kuphela ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza kungase kungabi yinto engabizi.
