Abstract

Wear phenomenon in engineering components impact operating efficiency and service life of materials due to the influence of surface interaction and different working conditions. Laboratory tests are utilized in simulating the mechanical and chemical wear mechanisms which are responsible for non-uniform aggregation of wear patterns in practice. Successive tribological studies on wear-resistant engineering materials in the last decade estimates friction and wear solutions at approximately 40%. This wear reduction technique comprises surface engineered coatings texturing, hardening, architecture as well as matrix composite, microstructures and reinforcing. Complexities of intermeshing factors combine to influence the effectiveness of developed test devices span over loads, speeds, temperature, pressures and ambience for various applications including automotive systems, nano/micro-electromechanical systems, atomic force microscopes and turbines. This study highlights the recent techniques in wear characterization, reduction and effects on engineering materials, and concludes that wear rate increased with applied pressure over time but decreases as the load decreases. Developed wear testers in accordance with American Society for Testing and Materials (ASTM) and European (EN) standards achieve 95-97% parametric accuracies with reduced cost. The major challenge with recent improvised design standards is instrumentation of test device to accommodate repeatability and reproducibility, as well as, optimal thermal cycling and cooling-rate process in developing automotive components like disc brake pads with complex shapes using additive manufacturing (AM‐fabricating) techniques.
