Abstract
A process for the co-deposition of fluorinated carbon and diamond material with electroless metal in which the electroless plating bath is formulated to contain an aqueous dispersion of the fluorinated carbon, the finely divided diamond material and an electroless metal salt in aqueous suspension. the plating bath can be used to plate workpieces wherein the fluorinated carbon and diamond material are co-deposited in a plated electroless metal matrix. It has been found that the use of a finely divided diamond material having an average diameter less than 10 nm provides not only improved bath stability but also facilitates the codeposition of the diamond material and fluorinated carbon with the electroless metal.
