The Effect of Ni-P Alloy Pre-Plating on the Performance of Ni-P/Ni-P-PTFE Composite Coatings
In order to obtain more excellent performance of composite coating, a layer of Ni-P alloy was plated firstly, then Ni-P-PTFE composite coatings was plated. If plating time ratio of electroless plating Ni-P alloy and Ni-P-PTFE composite plating was properlly controlled, performance of pure Ni-P-PTFE composite coating could be improved. The study have shown that the total plating time is 2 hours, and the plating time ratio is 1:1, and good bonding strength with the substrate, right hardness, low friction coefficient, good corrosion resistance of Ni-P /Ni-P-PTFE composite coatings have been obtained.
