Microstructure and wear resistance of Stellite-6/WC metal matrix composite coatings

The paper presents the study results of metal matrix composite coatings formed on S355 and B27 steels by laser cladding with powder technology. Powder mixture consisting of cobalt based alloy and tungsten carbides particles was used. The study consisted of production of the coatings using Trumpf TruDisk laser device equipped with 3-stream nozzle powder feeding system. Composite coatings were produced both on laboratory specimens as well as on agricultural tools. The constant value of feed rate equals 460 mm min-1 and different values of laser beam power (400, 550 and 700 W) have been used. The influence of laser beam power on microstructure, chemical composition and wear resistance on produced coatings have been investigated.
