Abstract
The paper presents the wear behaviour on a rotating disk which carried abrasive paper of laser cladding layers with high-speed steel powder type HS6-5-2 - M2 compared to steel samples of the same quality but heat treated in volume. To see how temperature affects the wear behaviour by abrasion of the laser cladding alloy and the classically hardened steel, samples have been heated to 450°C, 550°C, 650°C and 700°C during a four hour exposure, after which they were subjected to testing. It was monitored the hardness and wear mass variation with temperature and the variation of micro-hardness in the laser cladding layer. In order to point out the microstructural aspects of the samples metallographic analyses were performed.
