【 摘 要 】

Amorphous Ni-Fe-P alloy coating was prepared on thecopper substrate by electroless deposition. Silicon carbide particles were added into the suspension containing 5wt% NaOH to carry out erosion experiments on the coatings with the self-made erosion tester. The experimental results show that, due to the corrosion of the solution on the coating and the impact of SiC particles on the corrosion film and matrix metal, the maximum loss of coating quality occurs when the SiC particle size is 120 μιη at different impact angles. With the increase of impact angle, the mass loss of coating tends to increase. With the increase oftheslurry flow rate, the mass loss of coating increases.
