Abstract
PURPOSE: To prevent generation of scuffing by applying complex plating of the plating liquid with the compound of phosphorus and boron-nitride or sericite on the surface of the piston with the nickel plating bath as the base.
CONSTITUTION: The nickel coating is applied as the matrix, and the particle boron- nitride 5W50g/l or the sericite 5W100g/l which is lubricating and of which coefficient of friction is small is used as the entroid. Also, as the hardness of the lubricating compound plating is low as the coating, the compound of phosphorus 0.02W 0.5g/l is added. The surface is compound-plated by the conventional method with the plating liquid. The plating coat thus obtained is lubricating and has 500W700 micro Vickers hardness which is large as the hardness.
