Influence of periodic currents on the composition, physical-mechanical and functional properties of the electroplated composite Ag-W coatings

Abstract

Influence of pulse and reverse current on the composition, physical-mechanical and functional properties of Ag-W coatings was studed. It's established that adding tungsten oxides to composition of silver coating, depositing with pulse and reverse currents allow to reduce a grit size, to increase microhardness and wear resistance. Depositing of coatings with periodic currents increases a process efficiency and expands a technological capabilities of the electrophysical properties control of the electroplated composite coatings.
