Effect of carbide degradation in a Ni-based hardfacing under abrasive and combined impact/abrasive conditions

► Degradation process of carbides depends on the energy applied during hardfacing. ► Carbide/matrix interphase influences primary carbide content and matrix composition. ► Abrasive wear resistance depends on the level of carbide degradation. ►For abrasive material removal, a novel energy parameter is defined.
