Methods of control of the structure of coatings of molybdenum and tungsten in tungstate-molybdate melts

Abstract

The methods (the composition of the atmosphere above the electrolytic bath, the application of non-stationary current modes, conditions and parameters of electrolysis) were experimentally determined for control of the structure of molybdenum and tungsten coatings in tungstate-molybdate melts. The use of non-stationary current regimes for deposition of molybdenum and tungsten coatings with controllable structure allows to increase the surface hardness, wear resistance, abrasive and corrosion resistance of structural materials in a purposeful manner.
