Hard Chrome Plating

Hard Chrome plating is an electroplating process where chromium derived from a chromic acid solution is deposited onto a metal. Chrome plating helps resist corrosion and any natural wear that can occur.
This coating resists the natural wear it would normally experience by reducing friction. Hard Chrome provides a uniform micro-cracked pattern ideal for maximum corrosion protection. We can provide you with a thickness anywhere between 0.00005 to 0.020 inches. The hardness ranges between 68 to 70 HRC.

Electroless Nickel

The alloy composition utilized in the electroless nickel process improves hardness, lubricity and corrosion resistance. The electroless nickel process is an auto-catalytic reaction that distributes an even layer of a nick-phosphorus alloy onto a steel, copper or aluminum.
The material is then dipped into a bath of plating solution where a reducing agent reacts with the ions in the material to deposit the nickel alloy. The phosphorus percentage is what determines the metallurgical properties of the alloy, at TPPS we use 8 to 11 percent to provide the maximum corrosion protection.

Electroless Nickel Teflon (PTFE)

Applications for Electroless Nickel Teflon coating can be seen in a number of fields such as electronic, medical, appliances and automotive industries. Electroless Nickel Teflon (PTFE) is an advanced form of Electroless Nickel plating. The process is self-lubricating which allows for very low friction values, especially where sticking problems may occur. Electroless Nickel Teflon is a composite coating that has PTFE particles deposited into the electroless nickel layer. The plating is done through a precise autocatalytic process and is adjustable to meet the requirements of its many applications. Benefits include the nonstick surface which eases the molding operation by allowing easy release.  Electroless Nickel Teflon (PTFE) provides a non-wetting surface which repels a variety of potential contaminants.

Electroless Nickel Boron Nitride

The demand for Electroless Nickel Boron Nitride can be seen in plastic molds, medical components and automotive components.
This coating is a composite that has hexagonal boron nitride particles deposited into the electroless nickel layer. It is a hard, self-lubricating coat ideal for high wear applications. This coating holds a low coefficient of friction, making it ideal for sliding or friction wear applications. Electroless Nickel Boron Nitride can withstand higher temperatures (melting range 1650-1790 °F) and a higher load wear than Electroless Nickel Teflon (PTFE).
