Chromium plating (Cr III) A layer of decorative chrome 0.3 microns thick is deposited on the coating of glossy nickel, which gives the item a distinctive bluish gloss of chrome. Decorative chrome plating can be done on steel, copper, brass and stainless steel items. The surface intended for chrome plating must be smooth and shiny, so only parts made from light-drawn tubes, cold-rolled sheets or mechanically sanded and polished surfaces are considered for best results. The main corrosion protection of chrome plated parts is not given by chrome, but by deposits before chrome – in our process we use semibrigh nickel and bright nickel system (duplex nickel system). We apply decorative chrome from chloride type trivalent chromium Cr (III) chemistry which is in line with all ecology and environment protection laws of the 21st. century. Type of the chrome Cr III process is Trichrome Plus® from Atotech.

Kromiranje (Cr III) Na prevlaku sjajnog nikla taloži se sloj dekorativnog kroma debljine 0,3 – 0,5 mikrona, koji predmetu daje prepoznatljiv plavičasti sjaj kroma. Dekorativno kromiranje možemo izvršiti na predmetima od čelika, bakra, mesinga i inoxa. Površina koja je namjenjena kromiranju mora biti glatka i sjajna, pa prema tome dolaze u obzir samo pozicije izrađene od svjetlo vučenih cijevi, hladno valjanih limova ili mehanički brušenih i poliranih površina. Antikorozivnu zaštitu kromiranih predmeta ne daje krom, nego prevlake taložene prije kroma – polusjajni nikl i sjajni nikl (duplex nikl).
