Titanium atoms were alloyed into a polycrystalline alundum substrate using a various number of intense pulses consisting of plasma of the working gas and vapor and low energy ions of Ti eroded from electrodes of the rod plasma injector type generator. It appears that at a single pulse titanium always forms a thin metallic film not mixed with the substrate material. With increasing number of pulses...
The present study has shown that hardness and wear behaviour of (15%Co)-cemented WC alloys can be improved by boron ion implantation. The B+implantation was carried out at different temperatures. Three ion fluences have been chosen: 5x1016cm-2, 1x1017cm-2and 5x1017cm-2, each at an energy of 40 keV. The XRD analysis has shown that after implantation one observes a broadening of the XRD tungsten carbide...
