| Abstract Scope |
Metal matrix composites (MMC) offer high wear and temperature resistance for various applications. Tungsten carbide reinforced powders for additive manufacturing are usually produced by premixing reinforced and matrix particles. However, due to the density differences between the particles and the dissolution effect of the WC at high temperatures, the production of homogeneous MMC protective coatings remains a significant challenge. In this study, a new approach to produce homogeneous, with high wear resistance WC-metal matrix powder is presented. Cored WC-wires were atomized by wire arc thermal spray-based atomization method. The influence of atomization parameters and the different metal matrix alloys on the homogeneity, mechanical properties and wear resistance is discussed. The surface morphology, particle size distribution and dissolution behavior of WC-Metal powders were analyzed. After atomization, steel substrate was coated with the developed WC-Metal powders using laser melting deposition. The microstructure and hardness of the coated layers were characterized and measured. |
