Abstract

For wear demanding applications, the metal matrix composites (MMC) are often used due to their high wear resistance, and the tungsten carbide is often used as hard reinforcing particles. Nevertheless, there are still some limits of WC, mainly its deterioration due to heat load during laser cladding. Therefore, there is an effort to develop a new type of reinforcing particles with superior properties to WC. This study focus on analyzing microstructure and mechanical properties of laser cladded Ni-based coating reinforced with a new (TiW)C1-x carbide and compare it with the usual one with WC. In the new (TiW)C1-x based coating a higher amount of carbide particles remain undissolved thus providing with higher hardness and improved wear resistance.

Keywords: Laser cladding, wear resistance, MMC coatings
