NIPHOS® 964 / 964 HS Nickel Phosphorus Electrolyte

NIPHOS® 964 / HS is free of chloride, boric acid and ammonium. Apart from nickel, it contains no other heavy metals such as lead or cadmium (RoHS compliant). The phosphorus content of the coatings can vary from 6 – 13 % phosphorus. By adjusting the operating conditions, the phosphorus content can be adjusted in the range >10.5 % phosphorus. The hardness of the coatings is 550 HV 0.05 in the condition as deposited.

By using a combination of NIPHOS® and hard chrome, the thickness of the chrome layer and thus the amount of Cr6+ used can be reduced – while at the same time improving the properties of the whole layer.

Furthermore, layers of NIPHOS® 964 / HS can be used as a substitute for highly phosphorus-containing layers of electroless nickel electrolytes. Disadvantages of electroless nickel-phosphorus processes can be avoided by using NIPHOS® electrolytes without loss of properties.
