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. |
