Abstract
Electroless nickel (Ni) and composite nickel coatings (Ni+TiN) are investigated in this study. EFFTOM -Nickel Method for electroless nickel plating is applied. Nanosized TiN particles (50nm) are used as a strengthening material. The coatings are plated on ductile cast iron samples. The wear tests of the coatings by the classic model TABER ABRASER “disc to disc” are carried out. The observation of the samples microstructure by means of an optical metallographic microscope GX41 OLIMPUS and the microhardness measurements by Knoop Method are performed. The wear resistance, the thickness and microhardness of the samples before and after thermal processing at 290°C, 6 h are defined.
