Experiment of Compound Coating with（Ni/SiC）_P as Second Phase Particle

In order to increase wettability of(SiC)_P to metal matrix,the surface of(SiC)_P was treated through electroless plating,and clad(Ni/SiC)_P was obtained.Ni-P-(Ni/SiC)_P electroless plating compound coat uas prepared with the(Ni/SiC)_P as the second phase particle.Comparison of the Ni-P-(Ni/SiC)_P coat with common Ni-P、Ni-P-(SiC)_P coats manifested that the Ni-P-(Ni/SiC)_P coat has better performance,uniform structure,high sediment quantity and is thicker.
