摘要：

The elemental and phase compositions of diffusion boride coatings on a 94 wt.% WC-6 wt.% Co alloy were studied. The coatings were obtained by interaction between alloy plates and powdery TiB2 in an argon atmosphere. The distributions of tungsten, cobalt and titanium were studied by X-ray microprobe analysis. The phase distribution in the direction perpendicular to the coating surface was investigated by obtaining X-ray patterns of the coating. The upper layer was found to consist of orthorhombic CoWB with traces of TiC. The concentrations of both phases decrease in the depth of the coatings. © 1979.
