| Sažetak: | Title screen Phase composition, sizes of coherent scattering regions, hardness and friction coefficient of WC–TiC–Co hardalloy and “(Ti,Cr)N coating-on-alloy” system treated by high power ion beams (HPIB) are studied. HPIBtreatment was carried out with power densities from 4 to 16 J/cm2. The effect of HPIB pretreatment (4 J/cm2)before deposition procedure was studied. HPIB action with energy densities of 8–16 J/cm2 on hard alloyresults in partial fusion of tungsten and titanium carbides. The hardness of surface layer increases by twotimes and wear resistance improves. HPIB action on “coating-on-alloy” system leads to coarsening of (Ti,Cr)Ncrystallites, partial decomposition of (Ti,Cr)N and precipitation of chromium phase. Preliminary HPIBtreatment (4 J/cm2) followed by HPIB impact (16 J/cm2) provides best effect on wear-resistance of (Ti,Cr)Nsolid solution on hard alloy.
