Research on Wear and Erosion-corrosion Properties of M2052 Damping Alloy after Electroless Ni-Cu-P Plating

An amorphous coating with the thickness of 9.2 μm was obtained by electroless Ni-Cu-P plating on M2052 damping alloy. The surface and cross-section morphology, elemental compositions and phase structure of the coating were analyzed. The changes of surface energy, wear properties and corrosion resistance of the samples without and with coating were compared.The results show that the corrosion resistance of M2052 alloy improve after Ni-Cu-P plating.Compared with the substrate, the wear resistance and erosion-corrosion resistance of the sample after plating greatly improve.
