Nickel Gleam EP is a single-additive process designed to produce nickel-phosphorus alloy deposits over a wide range of current densities. The composition of the deposit produced is dependent on additive content and current density. The major use of the process is for high-speed application of diffusion-barrier deposits for gold or silver undercoats on ferrous alloy substrates. The alloy at 11% phosphorus produces a low melting point eutectic at 880°¼C. This alloy can be used for hydrogen-furnace brazing of Nimonics and stainless steels etc. The alloy at 5% phosphorus produces a deposit with low co-efficient of friction, which is desirable in connector applications.
