Abstract
Cu-P-silicon carbide (SiC) composite coatings were deposited by means of electroless plating. The effects of pH values, temperature, and different concentrations of sodium hypophosphite (NaH ₂PO ₂ H ₂O), nickel sulfate (NiSO ₄·₆H ₂O), sodium citrate (C ₆H ₅Na 3O ₇· 2H ₂O) and SiC on the deposition rate and coating compositions were evaluated, and the bath formulation for Cu-P-SiC composite coatings was optimised. The coating compositions were determined using energy-dispersive X-ray analysis (EDX). The corresponding optimal operating parameters for depositing Cu-P-SiC are as follows: pH 9; temperature, 90°C; NaH ₂PO ₂·H ₂O concentration, 125 g/L; NiSO 4·₆H ₂O concentration, 3.125 g/L; SiC concentration, 5 g/L; and C ₆H ₅Na 3O ₇·2H ₂O concentration, 50 g/L. The surface morphology of the coatings analysed by scanning electron microscopy (SEM) shows that Cu particles are uniformly distributed. The hardness and wear resistance of Cu-P composite coatings are improved with the addition of SiC particles and increase with the increase of SiC content.
