Description
We have experimentally studied fluctuations of power of an electric arc in different types of plasmatrons with different power supplies in the article. Influence of fluctuations of power of the plasmatron on technology parameters of a plasma stream (current, voltage, an enthalpy, temperature, speed of a plasma flow) and on process of forming of coatings at impulse plasma was experimentally shown that the nature of fluctuations depends from fluctuations of voltage of the power supply, plasmatron type and also from fluctuations of an electrical arc. The size of fluctuations of power can be 50-100%. It is experimentally shown that impulses of power of an electric arc are capable to complicate supply of sprayed powder in to the plasmatron. Such fluctuations do not make dispersion of the melted powder particles. In the work, we have drawn conclusions that large-scale pulsations are capable to worsen quality characteristics of plasma coatings significantly
