Munguva yekushandiswa, zvikamu zvesimbi zvinowanzoita electrochemical corrosion uye kemikari corrosion nekuda kwesimba renzvimbo yekushanda. Izvo zvakajairika mumaindasitiri ekushandisa kuvandudza nzvimbo dzepamusoro dzeworkpieces kuburikidza nepamusoro kurapwa tekinoroji uye kuwedzera iyo inorwisa-corrosion zvivakwa zveworkpieces. Iyi nyaya inosuma maviri epamusoro matekinoroji ane yakanakisa anti-corrosion zvivakwa: Dacromet pamusoro pekurapa tekinoroji.

Dacromet surface treatment tekinoroji ndeye anti-corrosion coating tekinoroji, inonyanya kushandiswa kudzivirira pamusoro pezvigadzirwa zvesimbi. Iyo inoshandisa iyo electroless plating nzira kuti ivhare zvakaenzana pamusoro pesimbi nedhizaini ye inorganic coating ine anti-corrosion zvivakwa. Kazhinji tembiricha yekugadzira inotenderera 300°C. Uku kupfekedza kunonyanya kuumbwa ne ultrafine flaky zinc, aluminium uye chromium, iyo inogona kunyatso kuvandudza kushora kwezvigadzirwa zvesimbi uye kurebesa hupenyu hwavo hwesevhisi. Iyo Dacromet process inogona kugadzira dense film layer ye4 ~ 8 μm pamusoro peiyo workpiece. Nekuda kwekupindirana kwezvikamu zve flake zinc nealuminium, inodzivirira corrosive media senge mvura neokisijeni kubva pakusangana nezvikamu zvesimbi. Panguva imwecheteyo, panguva yeDacromet processing , chromic acid inopindirana nemakemikari ne zinc, aluminium poda uye nheyo yesimbi kuti iite dense passivation film, ine yakanaka corrosion resistance.

Kazhinji, Dacromet pamusoro pekurapa tekinoroji ndiyo yakajairika simbi pamusoro pekurapa nzira. Dacromet tekinoroji inonyanya kushandiswa pakudzivirira-kuora kudzivirira, kunyanya kune screws uye fasteners. Inoshandiswa zvakanyanya kuvandudza kuoma uye kusimba kwezvigadzirwa zvesimbi. Abrasiveness uye corrosion resistance. Kune maworkpiece ane ese ari maviri kuoma uye anti-corrosion zvinodiwa, Crow tekinoroji inonyanya kushanda. Pakusarudza tekinoroji yakakodzera yekurapa kwepamusoro, inoda kusarudzwa zvinoenderana nezvinodiwa zvekushandisa.
