Preparation and Study of Cr-Nanodiamond Composite Co-Deposition
The preparation of electrolyte and the technical flow were summarized, the chromium based nanodiamond composite coating was prepared by composite plating process. The metallography structure of plating layer was characterzied, and the hardness, the element of plating layer were tested, the test results and reaction principle were discussed. It was found that the addition of nanodiamond increased the hardness of the coatings. When the concentration of DND in electrolyte is 2.0-3.0g/L,the plating time is about 15-20min, the maximum hardness was obtained.
