Abstract
The Ag-Ni-Co alloy coating is prepared in the low eutectic solvent system by pulsed power supply technology. Infrared spectroscopy and cyclic voltammetry are used to confirm that the addition of metal salts does not change the low eutectic solvent system. When the current density is 1 A/dm2 and the plating time is 40 min, the plating grain is mainly spherical; the coating is uniform and dense. After testing, the surface-specific resistance of the plating is only 1.295 mΩ·cm2, the microhardness reaches 214.8 HV, and the wear rate reaches 3.1. The corrosion resistance of the plating and the substrate is analyzed by a combination of macroscopic electrochemistry and microarea electrochemistry, and the results show that the corrosion potential of the plating reaches −0.141 V, and the corrosion current density reaches 1.299 × 10−7 A/cm2. The corrosion resistance of the plating is much greater than that of the substrate.
