| Abstract: |
HVOF spraying was used to prepare coatings from mechanical blends of Cr3C2+25NiCr and NiCrBSi based metal alloy powders. The aim of the work was to study the influence of addition of a metallic phase on tribological properties of the coatings in sliding conditions. Tribological properties of the coatings were characterised under dry sliding. Addition of NiCrBSi decreased the coefficient of friction in high temperature, pressure and sliding speed.
