Changes in the microstructure, composition and stress state of VK20 hard alloy surface layers bombarded with titanium ions were examined. Specimens were in the form of polyhedral sheets of VK20 hard alloy. The results of the metallographic and x-ray diffraction studies showed that bombarding the alloy with titanium ions changed the phase and chemical composition of the subsurface zones of the alloy and led to the formation of the Co/sub 6//W/sub 6//C phase and titanium carbide. The formation of these phases was associated with diffusion of carbon from the alloy and with heating the bombarded zone of the alloy to high temperature. Changes in the stress state were related to changes in the phase composition.
