Electroplating inzira iyo simbi inonatswa kubva mu electrolyte nekuita kweinoiswa ikozvino uye inoiswa pamusoro pechinhu kuti iwane simbi inovhara layer.
Galvanized:
Zinc inoshatiswa nyore nyore muasidhi, alkalis, uye sulfides.Iyo zinc layer inowanzoitwa passivated.Mushure mekupfuura mune chromate mhinduro, iyo passivation firimu yakaumbwa haisi nyore kusangana nemhepo yakanyorova, uye iyo anti-corrosion kugona inowedzerwa zvakanyanya.Mumhepo yakaoma, zinc haina kugadzikana uye haisi nyore kuchinja ruvara.Mumvura uye mumhepo yakanyorova, inopindirana neokisijeni kana kabhoni dhaikisaidhi kuumba oxide kana alkaline carbonic acid firimu, iyo inogona kudzivirira zinc kuti irambe ichiwedzera oxidize uye kuita basa rekudzivirira.
Zvishandiso zvinoshandiswa: simbi, simbi zvikamu
chrome:
Chromium yakagadzikana zvakanyanya mumhepo ine hunyoro, alkali, nitric acid, sulfide, carbonate solutions uye organic acids, uye inonyungudika zviri nyore muhydrochloric acid uye inopisa concentrated sulfuric acid.Iyo yakaipa ndeyokuti yakaoma, brittle, uye nyore kudonha.Yakananga chromium plating pamusoro pezvikamu zvesimbi se anti-corrosion layer haina kunaka.Kazhinji, multi-layer electroplating (kureva copper plating → nickel → chromium) inogona kuzadzisa chinangwa chekudzivirira ngura nekushongedza.Parizvino, inoshandiswa zvakanyanya kuvandudza kupfeka kuramba kwezvikamu, saizi yekugadzirisa, kuratidzira kwechiedza uye kushongedza.
Zvishandiso zvinoshandiswa: ferrous simbi, mhangura nemhangura alloy zero yekushongedza chrome plating, kupfeka-inodzivirira chrome plating
Copper plating:
Mhangura haina kugadzikana mumhepo, uye panguva imwe chete, ine yakakwirira yakanaka inogona uye haigoni kudzivirira mamwe masimbi kubva pakuora.Zvisinei, mhangura ine high conductivity yemagetsi, iyo copper plating layer yakasimba uye yakanaka, yakanyatsobatanidzwa nesimbi yakakosha, uye ine maitiro akanaka ekupukuta. Inowanzoshandiswa kuvandudza conductivity yezvimwe zvinhu, sezasi kwepasi. imwe electroplating, sechidziviriro chekudzivirira kudzivirira carburization, uye kuderedza kukwesha kana kushongedzwa pakutakura.
Zvishandiso zvinoshandiswa: simbi nhema, mhangura uye mhangura alloy nickel-plated, chrome-plated pasi layer.
Nickel plating:
Nickel ine kugadzikana kwakanaka kwemakemikari mumhepo uye lye, uye haisi nyore kuchinja ruvara, asi inonyungudika nyore mukunyungudutsa nitric acid.Zviri nyore kupfuudza mune yakanyungudutswa nitric acid, uye kukanganisa kwayo ndeye porosity.Kuti ukunde kusavimbika uku, multi-layer metal plating inogona kushandiswa, uye nickel ndiyo yepakati layer.Iyo nickel plating layer ine yakanyanya kuoma, iri nyore kupurisa, ine yakakwira mwenje inopenya uye inogona kuwedzera kutaridzika uye kuramba, uye ine yakanaka corrosion resistance.
Zvishandiso zvinoshandiswa: zvinogona kuiswa pamusoro pezvinhu zvakasiyana-siyana, zvakadai se: simbi-nickel-based alloys, zinc-based alloys, aluminium alloys, girazi, ceramics, plastiki, semiconductors nezvimwe zvinhu.
Tin plating:
Tini ine kugadzikana kwakanyanya kwemakemikari.Hazvisi nyore kunyunguduka mu dilute mhinduro dze sulfuric acid, nitric acid uye hydrochloric acid.Sulfides haina simba patin.Tin zvakare yakagadzikana mune organic acids, uye makomisheni ayo haana chepfu.Inoshandiswa zvakanyanya mumidziyo yeindasitiri yezvekudya uye zvikamu zvendege, kufamba neredhiyo.Inogona kushandiswa kudzivirira waya dzemhangura kubva pakukanganiswa nesarufa murubha uye sechidziviriro chekudzivirira kune asiri-nitriding.
Zvishandiso zvinoshandiswa: simbi, mhangura, aluminium uye alloys avo
Copper tin alloy:
Copper-tin alloy electroplating ndeyekuisa mhangura-tin alloy pane zvikamu zvisina nickel plating, asi zvakananga chromium plating.Nickel isimbi isingawanzowaniki uye yakakosha.Parizvino, copper-tin alloy electroplating inoshandiswa zvakanyanya muindasitiri ye electroplating kutsiva nickel plating, ine yakanaka anti-corrosion kugona.
Zvishandiso zvinoshandiswa: zvikamu zvesimbi, mhangura uye mhangura alloy parts.
