Electroless Plating

Electroless Plating Process

Electroless plating also known as chemical plating or auto-catalytic plating involves a chemical reduction where the reduced metal is the catalyst for the reaction. This gives the process engineering the ability to uniformly deposit metals without the application of external electrical energy.

Versatility is the key to our innovatively engineered electroless nickel plating processes. Depending on customers’ part performance specifications, deposits can achieve the required needs for hardness, wear and corrosion resistance, lubricity, solderability, as well as high-temperature performance.

Conversion coating a generic term used to refer to a coating produced by a chemical or electrochemical treatment of a metallic surface.

Chromate conversion coatings are used to enhance corrosion protection on various metal surface. It is usually applied by immersing the part in chemical bath at room temperature until a film of the desired thickness has formed, then removing the part, rinsing it and letting it dry.

This thin chemical coating has several desirable characteristics on the metal surface:
  • Enhanced corrosion resistance
  • Enhanced bonding ability
  • Electrically conductive

Our passivation process removes “free iron” contamination left behind on metal surface like stainless steel. These contaminants are potential corrosion sites that result in premature corrosion and ultimately result in deterioration of the component if not removed.

An in-depth technical know-how on materials and the passivation processes are crucial in achieving the desired results.
