АНАЛИЗ МОРФОЛОГИИ ПРИ ВОЗДЕЙСТВИИ ЭЛЕКТРОЛИТИЧЕСКОЙ СТРУИ НА ПОВЕРХНОСТЬ НЕРЖАВЕЮЩИХ СТАЛЕЙ

Abstract

The article is devoted to the study of the effect of an electrolytic jet on the surface of a metal anode. The studies were carried out in the electrolysis mode with a study of the transition to the electrolyte-plasma treatment mode. Special attention is paid to the mechanisms of formation of the morphology of the surface of stainless steels 08X18H9T, AISI 301, AISI 304. It is shown that for different steels, the process of electro-chemical dissolution of the anode material is accompanied by different mechanisms of dissolution of the micronerities of the microprofile. The current-voltage characteristics of the process in the voltage range in the range of 20-250 V. The effect of the decrease in the mass of the anode material on the current value is considered. The morphology of steels has been studied under different technological conditions and at different points of contact of the electrolytic jet with the surface. The criteria accompanying the transition to the electrolyte-plasma regime from the electrolysis regime are considered.The effect of an electrolytic jet on the risks formed by mechanical treatment on the anode surface is investigated. The influence of stress on the formed surface roughness parameter Ra is considered. The calculation of the electric field strength for surface nanodefects was performed in the Comsol Multithisics program. The results of this work can be used for the development of turbine blade processing technology, electrochemical cutting and nanoobrabotation of materials.
