Abstract:

Applications that require wear resistance use hard materials which are difficult to machine. The most common forming method is by grinding but that limits the part geometry that can be achieved. Using additive manufacturing to form parts will open the range of possible geometries and functionalities that have never been explored. In this study, the mechanical properties, microstructure, standardized wear testing and toughness were evaluated for as-built and heat-treated samples for a series of wear-resistant alloys developed to provide a range of properties for different tooling applications. The samples were prepared by printing with the laser powder bed fusion technique (LPBF) and then heat treated in different conditions.
