This paper reports the results of studies of the fretting wear resistance of specimens manufactured by laser microcladding. The initial materials were powders of Al-Si hypereutectic alloy which contained: (70–74)wt.% Al (26–30)wt.% Si. %. The influence of the laser microcladding parameters on hardness and fretting wear resistance of the cladded materials was investigated. It was found that hardness and wear resistance of the cladded material increased with the decrease of powder mass flow.
Key words: Laser microcladding / aluminum alloy / Al-Si system alloy / fretting wear
