Abstract

The article is considering the process of coating removal from the surface of complicated profile parts of high-temperature nickel alloys in plasma of electrolyte which is a neutral low concentration solution. Electrolytic plasma treatment is performed through the cathodic polarization of the treated part to avoid over echting of the base. The characteristic curve of the uniformity and velocity of the coating removal on electrolyte composition and processing optionssuch as voltage, temperature, ratio between period of direct current pulse packet and spacing interval is studied.
