Abstract

Abstract This study investigates the wear behaviour of a hybrid composite material reinforced with titanium diboride and zirconium carbide in LM13. The ASTM standard is followed for conducting wear tests, utilizing a pin-on-disc setup to assess the wear rate. An empirical relationship is established to predict the wear rate using statistical tool analysis of variance, and the model’s adequacy is checked. Low wear is observed at a sliding distance of 110 mm, sliding speed of 2.5 m s−1, and sliding load of 12.5 N. The observed low wear is attributed to the optimal level of reinforcement provided by titanium diboride and zirconium carbide. From the analysis of variance, sliding speed is identified as the major contributing factor to wear rate, followed by sliding distance and load. The reinforcement materials enhance the wear resistance of the hybrid composite and their effectiveness is particularly evident under the specified sliding conditions.
