Wear characteristics of Electroless Nickel Plating on carbon tool steel were investigated to find out the effect of base material hardness and phosphorus contents in nickel plating layer. The tests were conducted by ball on plate type reciprocal wear tester under the 90 N vertical load and the ball speed 25 mm/s. Three kinds of specimens were prepared with different type of heat treatment (austempered/annealed) and Ni-P contents in plating layer. Experimental results show that the higher hardness base material specimens have inferior wear resistance to lower hardness base material specimens. The contents of Ni-P ratio in plating layer is more dominant parameter than hardness of base materials.
