Metallic coatings. Electroplated coatings of zinc and zinc alloys on iron or steel with supplementary Cr(VI)-free treatment
| Published By | Publication Date | Number of Pages |
| BSI | 2016 | 22 |
This International Standard applies to electrodeposited zinc and zinc-alloy coatings on iron and steel with Cr(VI)-free passivation. The zinc-alloy coatings contain nickel or iron as alloying elements (referred to as zinc/nickel and zinc/iron coatings, respectively).
The main purpose of the coatings or coating systems is protecting iron and steel components against corrosion.
This International Standard specifies
-
the designations to be used for the above coating systems,
-
the minimum corrosion resistance to be achieved in specified test procedures, and
-
the minimum coating thicknesses required.
