STUDY THE EFFECT OF ZINC ADDITION ON DRY SLIDING WEAR RATE OF PURE ALUMINUM
Journal Title: Academic Research International - Year 2013, Vol 4, Issue 5
Abstract
In this research, the effect of Zinc addition to pure Aluminum to resist dry sliding wear had been studied using the pin-on-disc technique, to calculate the wear rate for pure Aluminum samples, and others with the addition of Zinc at different rates (1%, 3%, 5%), during sliding the test samples under dry sliding conditions on a disk of carbonic steel at different loads, variable slide speeds, and variable slide periods. The results showed that the wear rate decreases with increasing the Zinc proportion for the test samples. It has been noted that the increasing the applied vertical load leads to increasing the rate of wear and the rate of wear at 5% Zinc is less than the other rates. The results also showed that the rate of wear decreases with the increase of sliding speed for all the above added ratios. The results of X-ray diffraction for the samples of the test also showed the occurrence of the main phase (Al0.71Zn0.29) which has a great effect on reducing the rate of wear, as it increased with the increase of the proportion of zinc and for all the added percentages
