Abstract

The invention relates to pseudoalloys, in particular to a method for identifying the structure of the binding phase of pseudoalloys based on tungsten.The method, according to the invention, includes the anode corrosion of the tungsten phase of pseudoalloys in an electrolyte jet containing NaOH at a concentration of 50…150 g/L, for 0.5…1.0 min, at a space between the anode and cathode of 0.1…0.2 mm, a density of the electric current of 20…30 A/cm2, a temperature of the electrolyte of 20±2°C and the subsequent examination of the worked surface with an optical device.
