Abstract

The wear and corrosion resistance of Ni-P-SiC composite coating on AZ91D alloy were investigated in this paper. The surface morphology, microhardness, wear, and corrosion resistance of Ni-P-SiC composite coating under different deposition times were carried out by SEM, digital microhardness tester, and corrosion and wear tests. When the deposition time is 120 min, the microhardness of 641Hv is the highest, and Ni-P-SiC composite coating has better corrosion and excellent wear resistance, the values of E_corr, I_corr, and wear volume are -0.73 V, 0.78 µAꞏcm², and 1.04×10⁻³ mm³ , respectively. The properties of Ni-P-SiC composite coating are influenced by the deposition time. Ni-P-SiC composite coating deposited for 120 min has higher micro-hardness, better corrosion, and wear resistance.
