Abstract
[Purposes]This paper aims to solve the problem of the low hardness of the Ni-P composite coating itself.[Methods]Adding diamond micropowder is selected to prepare Ni-P/diamond composite coating.Firstly,the best process parameters for preparing Ni-P/diamond composite coating were ob-tained by orthogonal test,and then the influence of each process parameter on the mechanical properties of the composite coating was studied by single factor test.Finally,the composite coating under the best process parameters was characterized by SEM,XRD,and EDS.[Findings]The best process parameters were calculated according to the experiment.[Conclusions]The best process parameters for the prepara-tion of Ni-P/diamond composite coating are current density 4 A/dm2,diamond concentration 5 g/L,stir-ring speed 150 r/min,and coating temperature 60℃.The influence of each process parameter on the me-chanical properties of the composite coating is studied.
