Abstract

This study presents a comparative analysis of wear and frictional characteristics observed in two materials: a Zn-Al alloy and an in-situ reinforced Zn-Al/9 vol% ZrB₂ composite in the dry as well as in the lubricated sliding state.Furthermore, to highlight the potential applications of the Zn-Al/9 vol% ZrB₂ in-situ composite, a thorough comparative examination of its wear and frictional properties against commercially prevalent materials in tribological applications has been conducted. The results reveal promising outcomes, demonstrating comparatively lower wear and a higher frictional coefficient in dry sliding conditions. This unique combination of the developed material may be a promising candidate for use in possible braking and clutch materials systems. Conversely, in lubricated environments, the material exhibits low wear and a low COF, indicating its potential suitability for bearing and bushing applications. Moreover, this study not only enhances understanding of wear mechanisms but also opens the way for the innovative application of the Zn-Al/9 vol% ZrB₂ in-situ composite in various industrial scenarios. These findings align well with the increasing demand for multifunctional materials in resource-conscious and dynamic industrial environments.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
