摘要

Aiming at the issue of poor corrosion resistance in M2052 alloy and the damping performance degradation as the working temperature increases, this study focuses on enhancing the corrosion resistance of the M2052 damping alloy through a low-temperature (<60 °C) coating preparation method. A uniform Ni-W coating with a thickness of approximately 12 μm and a nanocrystalline structure was successfully obtained under a low current density condition. Compared with the uncoated substrate, the Ni-W-coated samples exhibited significantly enhanced hardness, reduced friction coefficient, and markedly improved wear resistance, with the dominant wear mechanism transitioning from abrasive/oxidative wear to mild adhesive wear. In 3.5 wt.% NaCl solution, the Ni-W coating significantly improves the corrosion resistance of the substrate due to its lower Icorr, higher Ecorr and higher impedance than M2052 alloy. After electrochemical corrosion, the Ni-W coating maintained its integrity and retained its cellular structure, while the M2052 alloy substrate underwent significant corrosion, resulting in homogeneous corrosion with a lamellar structure that stacked on top of each other. XPS results of corrosion in deionized water indicate that the corrosion of Ni-W coatings is controlled by a passivation-controlled mechanism, mainly through the formation of protective Ni(OH)2 and WO3 layers. DMA showed that the material’s damping capacity is moderately enhanced after low-temperature electrodeposition. This study demonstrates that low-temperature electrodeposited Ni-W coatings provide an effective surface engineering approach to simultaneously enhance corrosion resistance, wear performance, and damping functionality of Mn-Cu-based high-damping alloys.
