Ni/Ni-B electroplating method for selectively intensified wear-resistance

摘要

It relates to a boron (Ni / Ni-B) electroplating method, - the present invention is a nickel / nickel to selectively enhance the abrasion resistance of the specific portion; Provided in, but electroless plating using a reducing agent, carried out by mixing silver and gold electroplating, temperature display unit 8 and a thermometer 7 and a pH display 10 and connected to pH meter (9) of the plating tank 15 connected and a Ni / Ni-B in the electroplating process, the plating bath 15, the plating liquid inlet (13) plating liquid injection pipe base (2) to the installation (16) on the side in which to maintain the pH and temperature to an appropriate range that for ejecting the plating solution to the desired area at a 90 degree angle, and the circulation inlet of the discharged plating liquid from the plating liquid discharge port 14 of the plating tank 15 under pressure by using a chemical pump 12 to the plating liquid inlet (13) It characterized,; Assists to give enhanced abrasion resistance than the portion requiring high wear resistance, by applying a variety of wear-resistant materials used at high temperatures, it provides the effect that to have stable properties with respect to thermal stress.
