Diamond Coating


How does one deposit diamond grit by means of electroplating on to a surface.I want to make my own diamond files and diamond burrs.

This is usually done by suspending the diamond grit as a slurry in a nickel plating solution, Cornelius. It is a fairly proprietary process so it would be difficult to do yourself unless you were a very skilled plater with development time on your hands. Two possible routes to suucess would be to use a thickening agent in the solution, and/or to build a fluidized bed to keep the diamonds in solution.

This technology is the subject of a number of very aggressively defended patents, so you would have to be cautious to avoid infringement. A safer course might be to license the technology. Good luck.
