Microstructure and tribological characteristics of the coating were studied. The as-deposited microstructure mainly consists of Ni-rich gamma (Ni, Fe) phase, Cr7C3, CrB, Cr3C2, M23C6, Ni3B, and Ni3Si. Compared with that of the 304 L stainless steel substrate, the wear resistance of the coating greatly improves. The wear test demonstrates that the wear mechanism depends on wearing time and applied load. When the wearing time is short, the wear mechanism is abrasive wear under low load and adhesive wear under high load. When the time is relatively long, the wear mechanisms are adhesive wear and oxidation wear under low load; fatigue wear appears under high load. (C) 2012 Elsevier B.V. All rights reserved.
