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. Yielding excellent wear and corrosion resistance electroless nickel is an autocatalytic plating process resulting in a reflective layer of nickel phosphorous. It is the most common version of electroless nickel plating. The aluminum must be zincated first then either cyanide copper plated or electroless nickel plated before going on to the final decorative finish. It is deposited by immersion of parts in a solution of nickel salts and reducing agents at a temperature of 90 c.

The total build up plating process provides uniformity on all surfaces making post machining unnecessary when dimensions are accurate. 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. 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. Aluminum can be electroplated and in fact the overwhelming majority of chrome plated auto wheels today are cast aluminum.

The electroless nickel phosphorous content affects the properties of the deposit significantly including hardness corrosion resistance and magnetism. Arlington plating s apc 100 electroless nickel plating technology can be used on a wide range of applications including in automotive and industrial industries. Electroless nickel plating is a process that deposits an alloy of 90 nickel and 10 phosphorus on a wide range of metals. Comparatively this solution differs from other electroplating processes because it does not require an electricity source to coat the part.

Electroless nickel is a hard silver coloured coating comprised of nickel alloyed with between 4 and 14 phosphorus. Below is a brief overview of the electroless. So which is better aluminum anodizing or electroless nickel plating. Electroless nickel plating en is a process that uses a chemical reaction to co deposit it s nickel phosphorus coating onto a desired substrate.

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. Q a problems solutions.
