An Overview on Impact of Surface Roughness on Tribological Behaviour

Abstract

Surface tribological performance is important in many engineering applications, influencing factors like as friction, wear, and overall mechanical efficiency. This study delves into the intricate relationship between surface roughness and tribological behavior, providing a complete investigation of the surface topography's delicate impact on friction and wear characteristics. The investigation employs a rigorous approach that incorporates both experimental and theoretical methodologies. The findings highlight the importance of surface roughness in determining frictional forces and wear rates. At the microscale, asperity interactions and contact mechanics are examined, providing insight into the mechanisms that cause friction and wear. The study also investigates the impact of lubrication on tribological response, taking into consideration both boundary and hydrodynamic lubrication regimes. Advanced analytical models are built to correlate observed tribological behavior with specified surface roughness characteristics. This modeling approach simplifies the identification of essential elements impacting friction and wear, allowing the creation of predictive frameworks for optimizing surface topography in a wide range of engineering applications. This comprehensive study not only elucidates the influence of surface roughness on tribological behavior, but it also provides a roadmap for changing surfaces to increase frictional characteristics and wear resistance.
