Abstract
It is shown that nickel boron composite coatings can be obtained by electroplating nickel from a bath containing dispersed boron particles. This deposit heated to 300°C forms Ni-Ni3B composite. Further heating to 400°C converts it into Ni-Ni2B composite. Mechanical properties, corrosion resistance and wear resistance Ni-Ni2B composite are better than nickel or the electroless Ni-B composite in the as-deposited condition. The properties of heat-treated electroplated Ni-B composite are similar to that of heat-treated electroless Ni-B composites.
