Electroless Nickel Plating Aluminum

As is the case with many comparisons the answer is almost always it depends as far as strength and durability go nickel plating is the clear and obvious winner but the tradeoff is weight and flexibility.

Electroless nickel plating aluminum.

The aluminum must be zincated first then either cyanide copper plated or electroless nickel plated before going on to the final decorative finish. Electroless nickel plating an overview electroless nickel plating is offered by advanced plating technologies in both type iv medium phosphorous 6 9 p and type v high phosphorous 10 14. Comparatively this solution differs from other electroplating processes because it does not require an electricity source to coat the part. Below is a brief overview of the electroless.

The electroless nickel phosphorous content affects the properties of the deposit significantly including hardness corrosion resistance and magnetism. Electroless nickel en plating on aluminum. Yielding excellent wear and corrosion resistance electroless nickel is an autocatalytic plating process resulting in a reflective layer of nickel phosphorous. Electroless nickel plating en is a process that uses a chemical reaction to co deposit it s nickel phosphorus coating onto a desired substrate.

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. We are plating an aluminum heat sink with electroless nickel after plating our materials engineer cuts the part in half and the nickel peels in sheets from the surface of the aluminum. 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. So which is better aluminum anodizing or electroless nickel plating.

It is deposited by immersion of parts in a solution of nickel salts and reducing agents at a temperature of 90 c. Electroless nickel is a hard silver coloured coating comprised of nickel alloyed with between 4 and 14 phosphorus. Q a problems solutions. 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.

The total build up plating process provides uniformity on all surfaces making post machining unnecessary when dimensions are accurate. Electroless nickel plating is a process that deposits an alloy of 90 nickel and 10 phosphorus on a wide range of metals.
