Abstract

The wear and friction behaviour of coatings play a pivotal role in enhancing the performance and durability of materials in demanding applications. This study delves into the wear and friction characteristics of coating powders on grey cast iron surfaces using the detonation gun thermal spray coating method. Three distinct coating powders, titanium carbide (TiC), titanium chromium (Ti/Cr) and titanium cobalt (Ti/Co), are examined, with a focus on optimizing wear resistance and minimizing friction. The experimental investigation encompasses a range of parameters including rotational speed (rpm), applied load (N) and coating duration (min), systematically varied through a Taguchi experimental design. Wear rate (measured in mm³/m) and coefficient of friction (COF) are the key responses studied to evaluate the coating’s performance. Furthermore, the study employs a Multi-Criteria Decision Analysis (MCDA) approach, employing the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method, for optimization. This innovative methodology aids in identifying optimal parameter combinations that simultaneously enhance wear resistance and reduce friction. To comprehensively understand the contribution of individual factors, an analysis of variance (ANOVA) is conducted. This statistical technique elucidates the percentage contribution of each parameter and potential interactions, unravelling the intricate relationships governing wear and friction behaviour. The detonation gun thermal spray coating method, recognized as the pioneering high-velocity thermal spray technique, forms the cornerstone of this research. The combined integration of Taguchi experimental design, MCDA-TOPSIS optimization and ANOVA analysis establishes a robust framework for comprehensively exploring, optimizing wear and friction behaviour. The outcomes of this study provide valuable insights for engineers and researchers seeking to enhance material performance in challenging environments. By leveraging advanced methodologies, this research paves the way for tailored surface enhancements, contributing to improved wear resistance and friction behaviour in industrial applications.
