Electroless nickel plating is an auto catalytic reaction, used to deposit a layer of nickel-phosphorous alloy on a base material. Unlike electroplating processes, during electroless nickel plating, electric current is not necessary for the deposition of the surface layer. The advantage of this process is a uniform thickness of the deposited layer even on complicated shapes, in many cases removing the necessity for subsequent machining of the workpiece.

The deposited layer is highly corrosion resistant due to its low porosity and can be subsequently heat treated to achieve a hardness of up to 1000 HV. Electroless nickel plating is used in many different applications, particularly in applications demanding high hardness and corrosion resistance. Electroless nickel plating with heat treatment can be used in some applications as a non-toxic substitute for hard chrome plating. Bomex owns an electroless nickel plating line with the largest tanks in the Czech Republic.

 

We currently provide 2 types of electroless nickel plating. Plating with a medium content of phosphorus, which has excellent mechanical properties; and plating with a high content of phosphorus and with a strong resistance to corrosion and chemical damage.
