Features of Aluminum Alloy Microplasma Oxidation During Operation in a Polar Pulsating Current Regime

Аннотация

Results are given for microplasma oxidation process using a pulsating power source constructed on the basis of semiconductor elements. Features are revealed for microplasma oxidation in silicate electrolyte with performance of the process in a pulsating polar current in an anodic regime with prescribed signal rectangular shape. The dependence of microplasma process depending on aluminum alloy AMg5 surface treatment, and also mechanical properties of oxide coatings obtained on electric current pulse frequency in an object-electrolyte circuit part is demonstrated.
