INFLUENCE OF ELEVATED TEMPERATURE ON THE CHEMICAL COMPOSITION OF BOUNDARY LAYERS FORMING IN THE PRESENCE OF AN ANTIWEAR ADDITIVE OF VEGETABLE ORIGIN
Journal Title: Tribologia - Year 2013, Vol 251, Issue 5
Abstract
The effect of temperature on the chemical structure of boundary layers forming on steel surface during friction lubricated by poli-a-olefin oil containing antiwear additive of vegetable origin are investigated. The use of X-ray Photoelectron Spectroscopy (XPS) to analyse the surface of contact region showed evidence of the formation products of tribochemical reactions. Based on the results obtained for elevated temperature and previous results relating to ambient temperature, it is seen that thickness of the surface layer is significantly influenced by evaluated temperature, which changes the intensity of the proceeding reactions.
