Article Preview

The Ni-P/SiC composite coating was prepared by chemical deposition technique. The micro-structure and wear behavior of electroless Ni-P/SiC composite coating was investigated. The results show that the composite coating was dense and no any defects at the interface between substrate and electroless composite coating. Its thickness could reach 40 μm. Wear resistance was increased with the increasing content of SiC particles for single composite coating when the SiC concentration was less than 6g/L, then decreased with the increased SiC concentration. The wear resistance of gradient composite coating was improved above 16% comparing with the single composite coating. The wear resistance of T1 gradient coating was best for all electroless Ni-P/SiC composite coatings because the bonding strength was improved owing to the gradient change of SiC content.
