Study on electroless Ni-P-nano diamond composite plating

Electroless Ni-P-nano diamond composite plating using nano diamond suspensions with particle size under(150 nm) prepared by ourselves was studied.The influences of nano diamond content,stirring methods and surfactant types on composite plating were investigated.Results show that the electrolyte for the electroless nano-composite plating should have good stability,the plating rate is influenced by agitation methods and is increased with the addition of nano diamond.The composite surfactants can improve the coating property obviously.By surface morphology analysis,the(distribution) of nano diamond in the coating is shown to be homogeneous with uniform particle size of 100～200 nm.
