A comprehensive study of composites using traditional methods of testing mechanical properties in combination with methods of digital optical and scanning atomic force microscopy made it possible to establish stable correlations between the content of chromium diboride CrB2 additive with an average grain size WC, microstructure parameters, hardness, fracture toughness, ultimate strength at bending and compression. The optimal ratios of the components of the WC–Co-CrB2 system have been established, at which a finel...
