The effect of aging treatments on wear behavior of aluminum matrix functionally graded material under wet and dry sliding conditions

Abstract

This study investigated that the effect of aging treatments on wear behavior of functionally graded material (FGM) that was reinforced via being integrated with aluminum 2014 alloy (AlCu4SiMg) and 15 vol% SiC. The specimens were obtained via centrifugal casting technique, and then two different aging treatments were applied. Wear experiments were applied at 1.256 m/s constant sliding velocity, under two different loads and two different sliding distances for each condition via a pin-on-disc wear apparatus. The variations that occurred on wear behavior of cast and aged materials were analyzed. The results show that the minimum wear loss values were obtained under dry sliding conditions due to the aging processes. On the other hand, with increasing sliding distances under wet sliding conditions, the aging processes' effect was decreased on wear resistance. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.
