7075 Alloy

Metal matrix composites are of great interest in industrial applications for its light weight with high specific strength, stiffness and heat resistance. The processing of MMCs by stir casting process is an effective way of manufacturing. In this paper the comparison of mechanical properties of Aluminium 7075 as a base metal and varying composition of fly ash by 3 and 6 wt.% SiC and 7% fly ash as reinforcement is carried out. Scanning electron microscope was used to confirm the presence of SiC and fly ash. The composites with 6% SiC was found to have maximum hardness whereas composites of 6% and 5 % fly ash were found to have minimum hardness. The mechanical properties such as wear resistance were studied. From the results, it has been finalized that the addition of 6% SiC was identified to show the least wear rate.

Hot Pressing Sintering

In this paper, Al2O3/7075 composites were prepared by mechanical alloying with subsequent hot-pressing sintering, and the effect of Al2O3 nanoparticle on the mechanical and tribological behavior of 7075 was studied. The mechanical property results showed that the hardness and compressive strength of Al2O3/7075 composites first increased and then decreased with Al2O3 amount increasing, and 5 wt.% Al2O3 addition made the material exhibit excellent comprehensive mechanical properties. The tribological properties also indicated that 5 wt.% Al2O3 nanoparticle significantly improved the high-temperature wear resistance of 7075 alloys. Thus, all the mechanical and tribological results confirmed that the addition of Al2O3 nanoparticle was a better strengthening way for 7075 alloys at high temperatures.

Worn Surface

The tribological behavior of continuous frame ceramic reinforced Al-based alloy against Cr12 steel has been studied with oscillating dry friction and wear tester under the testing conditions of 70°C, 270°C, and 30min, and the load range is from 40N to 100N. The analysis of experimental results show that it is characteristic of abrasive wear and oxidation wear mechanisms for continuous ceramic/Al-7075 composites. The friction resistance of comb ceramic reinforced composite is better than foam ceramic reinforced composite, since the former is with continuous ceramic frame on the worn surface while the latest is with discontinuous hard convex on the plane; and the metal matrix filling in comb ceramic is not continuous in 3-D space, which leads to the deterioration of thermal metal softening at high temperature. Therefore, the composite reinforced by 2-D comb ceramic exhibits better high-temperature friction resistance than the one reinforced by 3-D foam ceramic.
