Aluminum is one of the abundant metals available on earth, by adding precise percentage of suitable alloying elements the aluminum alloy can exhibit properties nearer to pure metals but at lesser weight which enables them to be used in wide number of engineering applications. These works discuss the properties through results obtained from tensile tests conducted on UTM, and wears tests are conducted by pin-on-disk apparatus on the AL2014, AL2024, AL7075 specimens with different parameters like speed of the disk and temperatures for wear and for hardness. From analyzing the experimental results, we can say that for severe wear conditions, the workpiece displayed high amount of wear rate, friction coefficient, and we can also observe that the wear behavior of the aluminum alloy is largely influenced by the applied load. One should be aware of the presence of a critical load and if the load is applied beyond this load, it could have an unfavorable effect on the wear resistance of the aluminum alloy. The present work is proposed to optimize the experimental analysis by using Taguchi L9 method, which helps by reducing the number of experiments to be done from twenty-seven to nine, and then, the tensile test was conducted on the workpieces which are resized according to ASTME standards. |
