Abstract
Abstract Aluminium die cast A360-M1 master alloy with mass fraction (0.4 wt%) Al-5%Ti-1% B light metal matrix composite (LMMC) was prepared using the stir casting method. A three-level principle composite design test was developed using the boxbehnken response surface methodology. Variation in parameters such as load, sliding distance and sliding velocity were made in the range of 10–30 N, 500–1500 m, and 0.5–1.5 m/s respectively. Tribological dry sliding wear tests were performed as per the experimental design, using a pin-on disc setup at room temperature. Analysis of variance (ANOVA) was applied to study the impact of process parameters and their interactions viz., Load, sliding distance, sliding velocity on specific wear rate (SWR), frictional force (FF) and coefficient of friction (COF). The objective of this research is to recognize the parameters that significantly affect the output features such as specific wear rate, friction force, and COF of the aluminium die cast A360-M1 master alloy light metal matrix composites. Further, a mathematical model has been expressed by relating the boxbehnken response surface method in order to estimate the tribological characteristics. This work shows this A360-M1 master demonstrating the minimization of SWR, FF, and COF with response of load, sliding distance, and sliding velocity.
