Processing and Characterization of Tribological Properties of Al6061-TiB2 Composite by Taguchi Technique


In today’s engineering design and development operations, composite materials, which are the combination of two or more materials that are distinct from one another in form and chemical composition, are rapidly assuming increasing significance as a structural material. Many academics are working hard right now to create new and innovative materials for a variety of engineering applications employing various AMCs.

In order to explore the tribological behaviour, attempts are undertaken in this research to create Al-6061/TiB2 composites with varied weight percentages of reinforcement via in-situ stir casting. To assess wear loss and coefficient of friction, abrasive wear experiments were carried out using a pin-on-disc (POD) wear test device in accordance with the Design of Experiments (DOE). The wear loss and COF were further optimised using the Taguchi Technique, Analysis of Variance (ANOVA), and Regression studies. To further examine the wear behaviour of the produced composites, scanning electron microscopy (SEM) photographs of worn-out surfaces are employed. With a rise in the weight percent of reinforcement, wear loss and COF decrease. The ANOVA and regression analyses lead to the conclusion that reinforcement is essential to the growth of the Al 6061-TiB2 composite system.
