Abstract
In the present day engineering design and growth activities many Engineers and Scientists are striving hard to develop novel and better engineering materials, which accomplishes high strength, light weight and energy efficient materials since the problems of environment and energy are major threshold areas. In this paper attempts are made to study the abrasive wear loss and coefficient of friction of the Al 6061 reinforced with varying weight percentage of TiB2 composites by in situ process was investigated. The wear test was conducted using pin-on-disc wear testing apparatus (POD) as per the design of experiments (DOE).Taguchi Technique, Analysis of Variance (ANOVA) and Regression Analysis were adopted to optimize the wear loss. Further, Scanning Electron Microscopy images of worn out surface are carried to study the wear behaviour. Wear loss and Co-efficient of friction decreases with increase in the wt. % of TiB2 particles and noticed form the ANOVA and regression analyses that reinforcement plays a crucial role in the development of Al 6061-TiB2 composite system.
