Study of the thermally sprayed Zn coatings in the context of use in special purpose articles

The paper presents the results of operational tests of thermal sprayed zinc coatings of various thicknesses on non-alloy steel substrates. The resistance of coatings to: variable temperature cycles, increased ambient humidity, salt fog as well as the electrical resistance of the coating and its adhesion to the steel substrate were tested. It has been shown that Zn coatings has a high corrosion resistance in various atmospheric conditions and have satisfactory properties so they can be protective layers of machine parts used in the armaments industry.
