Iyo yepamusoro yekuputira maitiro inosanganisira hupfu hwekupfeka, Electro-plating, Anodizing, inopisa galvanizing, electro nickel plating, kupenda, uye zvichingodaro zvinoenderana nezvinodiwa nevatengi.Basa rekugadziriswa kwepamusoro nderekuedza kudzivirira kuora kana kungovandudza chitarisiko.Pamusoro pezvo, mamwe ekurapa aya anopawo akakwidziridzwa mechini kana emagetsi zvivakwa zvinopa mukushanda kwese kwechikamu.

Powder coating kana kumwaya- Nemhando iyi yekurapa, nhengo dzesimbi dzinoda kupiswa kusvika kune tembiricha inodiwa uyezve kunyura chikamu mumubhedha wakanyungudika kana kupfapfaidza hupfu pane chikamu.Nekurapa kwemashure, zvinoenderana neiyo chaiyo pfuma yehupfu.
Iyo poda inoshandiswa kazhinji iresin epoxy zvinhu kana Rilsan.

Electroplating-Ichi chiitiko chinoumba simbi yakatetepa yekunamira pane substrate.Iyo electroplating process inopfuura yakanaka-chaji yemagetsi ikozvino kuburikidza nemhinduro ine yakanyungudika simbi ions uye yakashata inochaji yemagetsi ikozvino kuburikidza nesimbi chikamu chinoputirwa.Masimbi akajairika anoshandiswa pa electroplating cadmium, chromium, mhangura, goridhe, nickel, sirivheri, tini, uye zingi.Inenge chero base simbi inoitisa magetsi inogona kuve electroplated kuti iwedzere kushanda kwayo.

Kemikari Kurapa-Iyi nzira inosanganisira maitiro anogadzira mafirimu matete e sulfide uye oxide nenzira yemakemikari reaction.Mashandisirwo akajairika ndeekupendeka kwesimbi, kudzivirira ngura, uye kugadzirwa kwenzvimbo dzinofanira kupendwa.Black oxide ndiyo yakajairika kurapa pamusoro pezvikamu zvesimbi uye "passivation" inoshandiswa kubvisa simbi yemahara kubva pamusoro pesimbi isina tsvina.

Anodic oxidation-Rudzi urwu rwekurapa kwepamusoro rinowanzo shandiswa simbi dzakareruka, senge aluminium uye titanium.Aya mafirimu e oxide anoumbwa ne electrolysis, uye sezvo ari porous, dhayi uye mavara ejenti anowanzo kutsanangurwa kune yakagadziridzwa yekunaka kutaridzika.Anodization yakajairika kurapa kwepamusoro iyo inodzivirira kuora pazvikamu zvealuminium.Kana kupfeka kuramba kuchidikanwa zvakare, mainjiniya anogona kutsanangura vhezheni yeiyi nzira inoumba yakakora, yakanyanya kuoma, yekeramic coating pamusoro pechikamu.

Hot Dipping-Ichi chiitiko chinoda kuti chikamu chinyikwe murata yakanyungudutswa, lead, zingi, aruminiyamu, kana solder kuti igadzire pamusoro pesimbi firimu.Hot-dip galvanizing inzira yekunyika simbi mumudziyo une zinc yakanyungudutswa.Inoshandiswa kudzivirira ngura munzvimbo dzakanyanyisa, njanji dzevarindi mumigwagwa dzinowanzogadziriswa neichi chepamusoro.

Painting-Kupendirwa kwepamusoro kunowanzo kutsanangurwa nevainjiniya kuti vawedzere chitarisiko chechikamu uye kusagadzikana kwekuora.Kupfapfaidza pendi, electrostatic pendi, dipping, brushing, uye poda coat pendi nzira ndedzimwe nzira dzinonyanya kushandiswa kuisa pendi pamusoro pechikamu.Kune marudzi akawanda ekugadzirwa kwepende kuchengetedza zvikamu zvesimbi munzvimbo dzakasiyana-siyana dzemuviri.Indasitiri yemotokari yaita otomatiki maitiro ekupenda mota nemarori, ichishandisa zviuru zvemarobhoti maoko uye kuburitsa mhedzisiro inowirirana.
