Effect of matrix chemistry and WC types on the performance of Ni-WC based MMC overlays deposited by plasma transferred arc (PTA) welding

Ground Engaging Tools (GETs) are subjected to severe abrasion during service in earth moving applications. Ni-based MMC overlays reinforced with tungsten carbides are ideal hardfacing candidates for critical surfaces on GETs. In this work, a combination of two types of Ni matrix (NiBSi/NiCrBSi) and...
