摘  要:
To strengthen the wear resistance of the NiP deposit layer, on the base of general NiP chemical deposit, the NiPSiC composite deposit and its wear resistance tests were carried out. By using the orthogonal design method, the optimum combination of the main factors - active agent,SiC,temperature, pH value and stable agent, etc by which the composite deposit technique will be effected-has been found. The effects on the deposit layer wear resistance of those factors were analyzed. The optimum technical alternative is active agent: 0 15 g·L -1 ,SiC 12 5 g·L -1 ,temperature 90 ℃, pH value 4 6 and stable agent 0 55 mg·L -1 . The test results showed that technique is stable and the deposit layer is bright, fine and has good wear resistance.
