Effect Of SiC Particle Size on the Tribological Properties of AA6061-Sicp Composite Prepared By Hot Pressing
AbstractThe aim of this study is to investigate the effect of SiC particle size on the hardness and wear behaviour of AA6061-SiCp composites. For this purpose, various size (8, 32 and 82 μm) with 30wt.% amount of SiC particles have been added into AA6061 aluminum alloy powders and Ø35x10 mm cylindrical blocks were produced by hot pressing at 525°C. Then, T6 heat treatment was applied to AA6061-SiCp composites aged at 180 °C for 18 h after solution heat treatment at 540 °C for 1 h. In order to identify the hardness and wear tests were performed to all samples under same conditions. Experimental results showed that with the increase of SiC particle size in the composites, the hardness decreased and wear resistance increased.
