The inclusion of in-situ TiC reinforcement in ZA37 alloy has shown potential for enhancing wear resistance. The impact of tribological test parameters on the abrasive wear response was analyzed using response surface methodology (RSM). Using tribological data, various machine-learning algorithms were trained to predict the wear behaviours of the developed composites. The performance measurements show that the machine learning models accurately predicted the abrasive wear response of test samples.
