‘KANIGEN’: CHEMICAL NICKEL PLATING

The Kanigen process of nickel deposition by catalytic chemical reduction is a practical production method for uniformly coating metals and non‐metals with a layer of hard, corrosion‐resistant amorphous nickel‐phosphorus alloy. This process has made available to industry a material with new and considerably improved surface properties. Both the technique and the product are unique. The amorphous high‐nickel low‐phosphorus alloy is deposited at a uniform rate on the piece being coated wherever it is in contact with the hot solution and whatever the shape. The non‐porous coating is hard but relatively brittle, adheres well to most properly pretreated basis materials, and has improved corrosion resistance (compared to pure nickel) which can be increased further by heat treatment.
