Manufacturing Method of Electroless Ni-P Nano-Diamond Composite Coating

摘要

The present invention provides nanometer (nm) nano-diamond composite electroless Ni-P plating with the size of the diamond The shape of the plated film by the plating conditions, the hardness (H _V ), relates to a composite electroless plating method having a wear and corrosion, was added to the nano-diamond powder in water at room temperature nanodiamond powder solution a step of controlling the concentration of; A step of dispersion by using an ultrasonic nano diamond powder solution after adjusting the concentration; Electroless nickel created group the dispersed nano-diamond powder solution was also added to the process to control the amount of acidity (PH); comprises, using diamond particles of nano size, and density of the particles, an ultrasonic dispersion time, PH specific conditions nanodiamond is dispersed in a uniform size adjusted to the (Nano Diamond) hardness by plating by the optimum conditions (H _V ) and has the effect of improving the wear and corrosion resistance.
