Abstract
Cr–P–W protective coatings are obtained by electrodeposition from water–dimethylformamide solutions based on chromium(III) chloride, with the addition of sodium phosphinate and sodium tungstate. The resulting alloys contained up to 8 wt % of phosphorus and 1.5 wt % of tungsten, as well as some carbon. The resulting coatings are characterized by satisfactory corrosion resistance in corrosive environments containing chloride ions. The number of through pores in the coatings became negligible with a coating thickness more than 15 μm, providing sufficient protective ability of the developed coatings.
