INVESTIGATION OF PRODUCTION OF FUNCTIONALLY GRADIENT MATERIAL BY ELECTROLESS PLATING

A new method of producing ceramic/metal functionally gradient material by electroless plating technique was proposed. The preparation of SiC/Ni P FGM was carried out by self made electroless plating facilities. The results show that the thickness of FGM coating and the gradient distribution of composition can be controlled by changing the parameters such as plating time, the addition speed and concentration of SiC particles after optimizing electroless plating technology. The good corresponding relationships among the SiC content, the microstructure and the mechanical property of the FGM are obtained.
