Abstract
In order to improve the properties of electroless composite coating,the Ni-P-(SiC)P electroless composite coating added nano-(SiC)P was prepared and various parameters on the Ni-P-nano-(SiC)P coating were studied systematically.The corresponding mechanism was analyzed and the heat-treatment of coating was also compared.The experimental results show that: main salt,reducing agent,temperature,pH,stirring speed and(SiC)P amount of Ni-P-(SiC)P coating deposition and deposition rate had greater influence.It was confirmd that the optimum concentration of the main salt was 28 g/L,the concentration of the reducing agent was 30 g/L,the temperature was 85±1 ℃,the pH was 4.5,the best stirring rate:200 r/mim;the optimal amount of particles:2 g/ L.
