ABSTRACT:
Water-soluble high molecular weight molecules are made present as a dispersing agent in a dispersion coating bath of a solution of a water-soluble nickel salt containing graphite dispersed therein, and a mold for molding glass is immersed therein in a manner that the mold serves as the cathode and the nickel metal serves as the anode in order to effect the electroplating while suppressing nickel or a nickel-based alloy in the film from granular growth in a vertical direction or in the direction of the plane thereof. On the inner surfaces of the mold is formed a film which comprises a matrix of nickel or the nickel-based alloy which as a whole has a flake-like form that is continuous and exists in an open cellular form and a graphite granule phase which is held in the open cells and is outwardly exposed on the surface. Since nickel is suppressed from growing like granules, the film exhibits excellent lubricating property, heat resistance, parting property, abrasion resistance and durability in combination, and is free from defects inherent in the prior art.
