Abstract

In this study, nickel was chosen as a reinforcement material for ZA40 zinc-aluminum alloy and it was produced by using the powder metallurgy technique. Composite samples were prepared by adding nickel reinforcements in the ratio of 0% -0.5% -1.5% -2% by weight. The prepared powders were ground in a planetary-type high-energy ball mill for 2 hours of mechanical alloying at room temperature and 60% relative humidity at 400 rpm. Composite samples were prepared from the ground powders under 520 MPa pressure and 445 ° C using the hot-pressing technique. The abrasion and friction forces of the composites were examined. Abrasion tests of nickel doped ZA40 composites were carried out using the ball on disc technique in an un-lubrication dry friction environment. The weight loss and friction coefficient results obtained showed that there are tribological differences between nickel reinforced composites and matrix material.
