Electrodeposition of alloys of the iron group metals with tungsten from citrate and gluconate solutions: Size effect of microhardness

Аннотация

For electrodeposition of binary alloys of iron group metals with tungsten from citrate and gluconate baths, a dependence of microhardness of the obtained coatings on the volume current density (VCD) was observed or, equivalently, the effect of the electrodeposition surface area at a given electrolyte volume and current density on the microhardness. It is shown that the observed size-technological effect of the microhardness of coatings can be attributed to structural modifications in the coatings (from crystalline to amorphous) associated with a change in VCD.
