A. Above 220 °C electroless nickel + 10% Phos begins to form Ni phosphides, recrystallize, harden and shrink. Its corrosion resistance is reduced. At temperatures above 400 °C it begins to lose hardness and corrosion resistance is reduced even more. Above 550 ° C its hardness will fall to around 200 HV.

2017-7-12 The electrical resistivity of EN deposits also varies with their phosphorus content. Pure metallurgical nickel has a value of 6.05 microohm-cm. Electroless nickel deposits containing 6 to 7 percent phosphorus have resistivities between about 52 to 68 microohm-cm. The resistivity of a deposit containing 2.2 percent phosphorus is 30 microohm-cm, while that of a deposit with 13 percent

2018-6-15 Electroless nickel plating – everything you need to know. Electroless Nickel Plating (ENP) is the deposit of a nickel-alloy coating by chemical reduction – without the electric current that’s used in electroplating processes. The majority of ENP for engineering purposes is a nickel phosphorus deposit containing 2 to 14% phosphorus.
