Electroless Nickel Plating Aluminum Process Steps

There is no need to pass an electric current through the chemical bath solution in order to initiate the plating process.

Electroless nickel plating aluminum process steps.

Electroless nickel phosphorus plating is a chemical process that deposits an even layer of nickel phosphorus alloy on the surface of a solid substrate like metal or plastic the process involves dipping the substrate in a water solution containing nickel salt and a phosphorus containing reducing agent usually a hypophosphite salt. For example a common process is to use a 6 5 oz gal sodium hydroxide solution. Electroless nickel plating tutorial. Electroless nickel is applied by heating the nickel bath to 195 f and then immersing the part to be plated into the bath for 15 60 minutes depending on the desired thickness.

However to electroless nickel plate or any other plate onto aluminum alloys successfully with good adhesion the oxide film must be removed and remain so during plating deposition. The aluminum parts must be cleaned to remove greases oils and other soils. En plating is selected because of its ability to protect aluminum from hostile environments and to make a hard wear resistant surface that allows aluminum to be. Plating aluminum with electroless nickel is not difficult.

The process of adding an electroless nickel plating to a metal surface is an autocatalytic chemical reduction. It is the most common version of electroless nickel plating. The electroless nickel plating process is simpler than its counterpart electroplating. Electroless nickel plating is a form of alloy treatment designed to increase resistance and hardness in a metal or plastic.
