Abstract:
In general, hard materials for tooling and wear resistant applications are very difficult to machine with the most common forming method being grinding. Utlizing a grinding operation severly limits the shape of the final product which can be acheived. Additive manufacturing, specifically Laser Powder Bed Fusion (LPBF), alloys for intricate shapes to be formed form most all alloy materials. However due to their brittle nature many of the materials with high hardness tend to crack in the LPBF process. This paper highlights the mechanical properties and microstructure of a family of wear resistance alloys that can be used in LBPF for a range of applications (from alloy steels to stainless steel). In addition to mechanical properties, case studies of the materials in real-life applications are presented and the wear mechanisms are reviewed and compared to their machined counter parts.
