Application: Aluminum or ductile iron parts
- Electroless Nickel is applied by submerging the part in a well-agitated bath which usually operates at between 180°F to 190°F. The bath chemistry requires closer control than that of most plating baths and is very susceptible to contamination.
- Electroless Nickel plating differs from electroplated nickel in that the deposition is autocatalytic. This means that the nickel is deposited on a substrate material without the use of external electrical current.
- Many of the properties of Electroless Nickel are superior to those achieved by electroplating. Corrosion and chemical resistance are better, ductility is improved, the deposit is harder (especially after heat treating), and the magnetic properties are different.
- One of the important features of Electroless Nickel is the ability to obtain deposits of uniform thickness even on confined inside surfaces.
- To ensure good coating adhesion, every part must be thoroughly cleaned of all dirt, oils, and oxides prior to plating. This preliminary cleaning process can be more involved than the plating process itself.
- Many varieties of Electroless Nickel are available. For the most part, the engineered coatings can be divided into three categories: low, medium, and high-phosphorus deposits. The level of phosphorus directly affects how hard and how well the deposit resists corrosion. The higher phosphorus deposits have very good corrosion resistance, but are softer than the low phosphorus deposits. Conversely, the low phosphorus deposits are harder but not quite as resistant to corrosion.
