In the electroless nickel process, electrons are generated by chemical oxidation reactions in the bath itself, without the need for an external current, which is particularly suitable for precision parts or workpieces with areas that are difficult to access. The treated surface produces a good degree of hardness that can be achieved with a low phosphorus content (3-7%). Corrosion protection can also be improved, whereby a high phosphorus content (10-14%) is advantageous. At Rieger, we offer an optimum compromise with a medium phosphorus content of 9-12%, which ensures both good corrosion protection and high hardness.
