Surface modification of Aluminium alloy 5083 reinforced with Cr2O3/TiO2 by friction stir process 2019-28-0179
Surface properties have vital role in overall performance of parts like brake shoe pad. The mechanical and residual stress measurements of aluminium alloy 5083 were investigated on friction stir processed plates using reinforcements of chromium oxide (Cr2O3) and Titanium di oxide (TiO2) separately as well as combination of these powders. A comparative analysis was performed to study the effects of reinforcements and tool type (cylindrical and threaded) keeping the FSP parameters and volume fraction of reinforcements as constant. This investigation shows that there was a significant increase in surface hardness (118 HRC) as well as decrease in residual stress compare to the base metal. This study also reveals that the threaded tool with a reinforcement of Cr2O3 and TiO2 reflected better mechanical properties than the cylindrical tool. The SEM image shows that the even distributions of reinforcement particles are presence in the processed zone. Mechanical properties like surface roughness, surface hardness and residual stress of samples were investigated. The significant improvement in the surface plates can be used in brake pad in automobile industries.
