Experimental investigate of the wear and friction performance considering effects of surface topography and lubricant

Abstract

The wear and friction performance are two important concerns for most friction pairs. Under heavy load conditions, even lubricant exists between surfaces, sold contact and wear phenomenon may take place and lead to a higher friction when the oil film cannot fully support the load. Surface topography, in which roughness and texture are included, and lubricant characteristics, may be effective in prolonging the wear life and reducing the friction in engineering practice. In this study, these effects are experimentally investigated. The results show that appropriate options of surface topography can enhance the oil lubrication and reduce the wear. Moreover, the MoS2 based oil additive can help to form an anti-wear and low friction tribo film on surfaces. Application of both the appropriate surface topography option and lubricant additive has potential to save energy and prolong the wear life effectively.
