Abstract
Purpose
The purpose of this study is to evaluate the effect of water contamination on ageing of lubricants.
Design/methodology/approach
The viscosity, total acid number and Fourier transform infrared spectrum of a series of lubricants after ageing with water were studied. The tribological performance (friction and wear) of the aged lubricants was also analyzed, followed by X-ray photoelectron spectroscopy analysis on the selected post test samples to study the tribochemical features of the tribofilm.
Findings
The results were also compared with Part I of this study, and it was found that ageing has a different impact on lubricants and tribological performances based on the physical and chemical properties when water is present in the lubricants.
Originality/value
This paper is a continuation of Part I of this study and gives an understanding on the impact of water on the lubricants and related tribological and tribochemical performance.
