SIGNIFICANCE OF SILICATE ELECTROLYTE-COMPOSITION IN ANODIC-CATHODIC MICROARC PROCESSES

The increments of thickness of coating and weight of the sample of d16 T aluminum alloy specimens in silicate bath were studied upon varying the water glass modulus. Variations of the electric held intensity in a growing oxide layer were phenomenologically considered under anodic- cathodic microarc conditions. A mutual dependence between the type of discharge, the coatings formation rate, and the electric field variati on was derived. To summarize the results and provide thorough analysis and interpretation, further quantitative investigations of the electr ic held variation are planned.
