Annotation
The paper is devoted to selection of compositions of metallographic reagents for investigation of structural components of deposited layer of composite material on the basis of powder high-speed steel 10R6M5 with addition of titanium carbides (TiC) and tungsten carbides (WC), obtained by method of induction deposition. Method of induction surfacing makes it possible to obtain thin layers of carbide steel on billet surface. By selecting the components of the batch, it is possible to obtain the desired properties, such as hardness, wear resistance. For metallographic reagents, a sample with a 10 percent tungsten carbide content obtained by induction surfacing
was selected. Compositions of metallographic reagents were selected in the work, the processing technology was determined, including the exposure time and temperature of the reagents. The results of using metallographic reagents on samples confirm metallographic studies using optical microscopy. Four metallographic reagents are shown, each of which is aimed at identifying certain phases that, according to the results of research, are able to separate carbide phases from a solid solution. Metallographic reagents of different composition during different processing times are able to separate carbide phases by the metals prevailing in them. The separation takes place along a gradient of colors, while a certain color corresponds to its own morphology of the carbide phase. As a result, the possibility of using metallographic reagents for the study of carbide steel with its specific distribution of carbides of different morphology and composition was proved.
