Muindasitiri yekugadzira ma electroplating, pulse power electroplating yakakwezva kutariswa nekuda kwekushanda kwayo kwepamusoro-soro kwekuputira. Kana ichienzaniswa neDC electroplating yechinyakare, inogona kuwana machira ane makristaro akapfava, akafanana, uye akachena zvakanyanya. Ehe, pulse electroplating haina kukodzera mamiriro ese ezvinhu, ine huwandu hwayo hwekushandisa.
Saka, ndeapi mashandisirwo makuru e pulse electroplating? Izvi zvinotanga nezvakanakira zvakawanda.
1. Kugadzirwa kwekristaro kwejira iri kwakanyatsonatswa
Munguva yekufambisa kwepulse, simba guru rinogona kusvika kakawanda kana kutopfuura kagumi pane simba guru reDC. Kuwanda kwesimba guru kunotungamira kune simba guru, zvichiwedzera zvakanyanya huwandu hwemaatomu anonamirwa pamusoro pe cathode. Mwero we nucleation unokurumidza kupfuura mwero wekukura kwekristaro, zvichikonzera kuti pave ne crystallized coating yakanaka. Rudzi urwu rwe coating rune simba guru, kuomarara kwakanyanya, maburi mashoma, uye runodzivirira ngura zviri nani, runodzivirira kupfeka, welding, conductivity, nezvimwe zvinhu. Nokudaro, pulse electroplating inoshandiswa zvakanyanya muminda inoshanda ye electroplating inoda kushanda kwepamusoro.
2. Kugona kuri nani kupararira
Kuisa ma electroplating epulse kune kugona kukuru kwekupararira, izvo zvinonyanya kukosha kune mamwe ma electroplating ekushongedza. Semuenzaniso, kana goridhe kana sirivha ichiisa ma workpieces makuru, kuisa ma electroplating epulse kunogona kuita kuti ruvara ruve rwakafanana uye mhando igare yakasimba. Panguva imwecheteyo, nekuda kwekuwedzera nzira yekudzora yekunze, kutsamira kwemhando yekuputira pamvura yekugezera kunodzikira, uye kutonga kwekushanda kuri nyore. Naizvozvo, mune mamwe ma electroplating ekushongedza anodiwa zvakanyanya, kuisa ma electroplating epulse kuchiri kukosha. Ehe, kune ma electroplating ekudzivirira echinyakare, akadai semabhasikoro, zvisungo, nezvimwewo, hazvidikanwi kuishandisa.
3. Kuchena kwakanyanya kwekuputira
Munguva yekubuda kwemhepo, mamwe maitiro akanaka ekubviswa kwemvura anoitika pamusoro pe cathode, akadai segasi rehydrogen rakanyungudutswa kana tsvina ichibviswa yodzokera kumushonga, nokudaro ichideredza hydrogen embrittle uye inovandudza kuchena kwejira. Kuchena kwakanyanya kwejira kunowedzera mashandiro aro. Semuenzaniso, pulse silver plating inogona kuvandudza zvakanyanya kuchinjika, kufambisa mvura, kuramba mavara, nezvimwe zvinhu, uye ine kukosha kwakakosha mumauto, zvemagetsi, zvemuchadenga, nedzimwe nzvimbo.
4. Kukurumidza kudonha kwevhu
Vamwe vanhu vangafunga kuti pulse electroplating ine mwero wakaderera wekuisa ma electroplating pane direct current electroplating nekuda kwekuvapo kwenguva yekudzima. Kutaura zvazviri, hazvina kudaro. Mwero we sedimentation unoenderana nekugadzirwa kwehuwandu hwemagetsi uye kushanda kwemagetsi. Pasi peavhareji yehuwandu hwemagetsi, pulse electroplating inowanzo wedzera nekukurumidza nekuda kwekudzoreredzwa kwehuwandu hwema ion munzvimbo ye cathode panguva yekudzima, zvichikonzera kushanda kwemagetsi kwakakwira. Chinhu ichi chinogona kushandiswa mukugadzirwa kwemagetsi kunoenderera mberi kunoda kuiswa nekukurumidza, senge waya dzemagetsi.
Ehe, pamusoro pemashandisirwo ataurwa pamusoro apa, nekufambira mberi kwetekinoroji, magetsi epulse ari kuramba achiwedzera mashandisirwo awo munzvimbo dzakadai se nanoelectrodeposition, anodizing, uye electrolytic recovery. Kune electroplating yakajairika, kushandura kuita pulse electroplating chete kuti uvandudze kushanda zvakanaka kwekugadzira kungasave nemutengo wakaderera.
