Kwishishini le-electroplating, i-pulse power electroplating itsale ingqalelo ngenxa yokusebenza kwayo okuphezulu kokugquma. Xa kuthelekiswa ne-DC electroplating yendabuko, inokufumana ukugquma okunekristale ezicolekileyo, ezifanayo ngakumbi, kunye nobunyulu obuphezulu. Kakade ke, i-pulse electroplating ayifanelekanga kuzo zonke iimeko, inomlinganiselo wayo wokusetyenziswa.
Ngoko ke, zeziphi iindlela eziphambili zokusebenzisa i-pulse electroplating? Oku kuqala ngeenzuzo zayo ezininzi ezibalaseleyo.
1. Ukwakheka kwekristale kwengubo kucociwe ngakumbi
Ngexesha lokuqhuba kwe-pulse, i-peak current inokufikelela izihlandlo ezininzi okanye ngaphezulu kweshumi kune-DC current. Uxinano oluphezulu lwamandla lukhokelela kwi-overpotential ephezulu, nto leyo enyusa kakhulu inani lee-athomu ezifakwe kumphezulu we-cathode. Isantya se-nucleation sikhawuleza kakhulu kunesantya sokukhula kwe-crystal, nto leyo ebangela ukuba i-crystallized coating ibe ncinci. Olu hlobo lwe-coating lunoxinano oluphezulu, ubulukhuni obuphezulu, ii-pores ezimbalwa, kunye nokumelana nokugqwala okungcono, ukumelana nokuguguleka, ukuwelda, ukuqhuba, kunye nezinye iimpawu. Ke ngoko, i-pulse electroplating isetyenziswa kakhulu kwiindawo ze-electroplating ezisebenzayo ezifuna ukusebenza okuphezulu.
2. Ubuchule obungcono bokusasaza
Ukufakelwa kwe-pulse electroplating kunamandla amahle okusasaza, nto leyo ebaluleke kakhulu kwi-electroplating yokuhombisa. Umzekelo, xa igolide okanye isilivere ifakela izinto ezinkulu zokusebenza, ukufakelwa kwe-pulse electroplating kunokwenza umbala ufane ngakumbi kwaye umgangatho uzinze ngakumbi. Okwangoku, ngenxa yokongezwa kwendlela yokulawula yangaphandle, ukuxhomekeka komgangatho wokugquma kwisisombululo sokuhlamba kuyancitshiswa, kwaye ulawulo lokusebenza lulula. Ke ngoko, kwezinye ii-electroplating zokuhombisa ezifunwa kakhulu, ukufakelwa kwe-pulse electroplating kusenexabiso lazo. Kakade ke, kwi-electroplating yokuhombisa eqhelekileyo, efana neebhayisekile, izibophelelo, njl.njl., akufuneki ukuyisebenzisa.
3. Ubunyulu obuphezulu bokugquma
Ngexesha lokuphelelwa ngamandla, ezinye iinkqubo zokufunxa kakuhle ziyenzeka kumphezulu we-cathode, ezifana negesi ye-hydrogen efunxwayo okanye ukungcola okuphumayo nokubuyela kwisisombululo, ngaloo ndlela kunciphisa ukubhitya kwe-hydrogen nokuphucula ubunyulu bengubo. Ubunyulu obuphezulu bengubo buphucula ukusebenza kwayo. Umzekelo, i-pulse silver plating inokuphucula kakhulu ukuwelda, ukuqhuba kakuhle, ukumelana nombala, kunye nezinye iimpawu, kwaye inexabiso elibalulekileyo kwimikhosi, kwi-elektroniki, kwi-aerospace, nakwamanye amacandelo.
4. Izinga lokutyibilika kwenkunkuma ngokukhawuleza
Abanye abantu banokucinga ukuba i-pulse electroplating inezinga eliphantsi lokufaka i-electroplating kune-direct current electroplating ngenxa yokubakho kwexesha lokucima. Enyanisweni, akunjalo. Isantya se-sedimentation sixhomekeke kwimveliso yoxinano lwangoku kunye nokusebenza kakuhle kwangoku. Phantsi koxinano lwangoku oluqhelekileyo olufanayo, i-pulse electroplating idla ngokufaka i-deposit ngokukhawuleza ngenxa yokubuyiselwa koxinzelelo lwe-ion kwindawo ye-cathode ngexesha lokungasebenzi, okubangela ukusebenza okuphezulu kwangoku. Olu phawu lungasetyenziswa kwimveliso ye-electroplating eqhubekayo efuna ukufakwa ngokukhawuleza, njengeentambo ze-elektroniki.
Kakade ke, ukongeza kwizicelo ezikhankanyiweyo apha ngasentla, ngokuqhubela phambili kwetekhnoloji, izixhobo zamandla e-pulse nazo zihlala zisanda ukusetyenziswa kwazo kwiindawo ezifana ne-nanoelectrodeposition, i-anodizing, kunye nokubuyiswa kwe-electrolytic. Kwi-electroplating eqhelekileyo, ukutshintshela kwi-pulse electroplating kuphela ukuphucula ukusebenza kakuhle kwemveliso kusenokungabi loqoqosho.
