“…In addition, very high contact pressures are present in an engine, which render lubrication challenging, e.g. 1-2 GPa in the case of cam and follower [1,3,4]. The most widely used extremepressure additives-used to protect such components against wear-are zinc dialkyldithiophosphates (ZnDTP) [5].…”

Antiwear additives, such as zinc dialkyldithiophosphate (ZnDTP), find application in many different industrial sectors. Although it is understood that certain ZnDTP concentrations need to be used to achieve an effective antiwear performance, there has been very little work published concerning the effect of temperature on the interactions of the additive and its adsorption mechanism on steel. In this article, 100Cr6 (52100) steel ball-on-disc experiments under solutions of zinc dialkyldithiophosphate (ZnDTP) in poly-a-olefin (PAO) were performed at different temperatures, ranging from 25 to 180°C. The discs were analysed after the experiments by means of small-area, imaging and angle-resolved X-ray photoelectron spectroscopy (XPS). The composition of the reaction film was found to change as a function of the applied temperature and also to vary within the film as a function of depth: Longer polyphosphate chains were found at higher temperatures as well as towards the outer part of the reaction film.

“…A linear [6] wear law has traditionally been used in studies of rolling-sliding contacts such as roller-bearings [3], cam followers [4] and gears, [5] and states that wear is proportional to the normal load and the sliding distance.…”

“…Flodin also conducted experiments to correlate theoretical results with experimental results. Not long after the initial gear wear simulation, a very difficult simulation of wear at the contact between a cam and a follower was performed by Hugnell et al [19]. The contact is a rolling and sliding contact between the cam and the follower, which is rotating at the same time as it is moving.…”

Introduction Can the wear process be modelled and simulated?The wear process can be modelled and simulated, with some restrictions. If we know the operating wear process, or how to model the wear process, we can also simulate and predict wear. In this presentation I will first outline how to use simplified estimations in machine design, and thereafter indicate how to perform more detailed wear simulations.
