The functional properties of ternary Co-W-Zr(ZrO2) alloys obtained in a pulsed mode from pyrophosphate-citrate electrolytes are discussed. The obtained coatings are characterized by a uniformly developed surface without cracks and a sufficiently high and reproducible microhardness. It was determined that the size of the globules on the alloy surface decreases with increasing of the current density to 10 A/dm2. It was found that increase of temperature favorably affects the current efficiency of the alloy and the microhardness of the Co-W-Zr(ZrO2) coating. The modes of electrosynthesis of the coatings by cobalt-tungsten-zirconium alloys are substantiated, an their influence on the functional properties of the alloy and current efficiency is investigated.
