ABSTRACT: Taguchi methods have proved to be successful over the last two decades for improvement of
product quality and process performance. This study is carried out to simultaneously
optimize the tribological properties: wear rate and frictional force of aluminum metal matrix
composite. Al-Cu-Mg alloy reinforced with 6 Wt % of titanium dioxide was prepared using
stir casting method. Dry sliding wear test was conducted to understand the tribological
behavior of samples. The experiments were conducted as per the Taguchi design of
experiment. The wear parameters chosen for the experiment were: sliding speed and load
and sliding distance. Each parameter was assigned three levels. The experiment consists of
27 tests according to L27 orthogonal array. Signal to noise ratio analysis has been carried out to determine optimal parametric condition, which yields minimum wear rate and
frictional force. Harrington’s desirability functional method is adopted for multifunctional
optimization of tribological parameters and the confirmation experiments were conducted to
verify the predicted model.
