Electroless nickel/diamond composite plating


We are interested in plating a composite electroless nickel diamond particle coating. Can someone give me an idea of how such a system is set up and where one can get the diamond particulate?

Thanks in advance for your help,

I know that at one time General Electric was offering these diamond particulates but I'm not sure if they still do. This is a field which is quite highly developed and where numerous patents are in place. You might want to start with Surface Technology [Trenton, NJ] as they have specialized in this for decades.

I just read an article by this Surface Technology folks in the Jan. 2000 issue of Metal Finishing magazine. References also mention several patents.

Hi Joel,

Are you looking to actually plate the diamond particles with EN for use in making abrasive tools such as grinding wheels, which as Ted points is a product that GE specializes in, or are you looking to coat a substrate with an EN/diamond composite?
