“…The previous mechanisms are probably caused by loading the material deformed on the scratch sides in previous cycle. In fact, we showed in previous study [20] that the distorted material on the scratch side can influence the wear mechanisms. The results also show that work hardening improves wear resistance and the ratio between the scratch sections for the annealed and the work hardened state is about two.…”

“…When analysing this damage, caused in service, various morphologies and wear mechanisms corresponding to mild and severe abrasion are apparent. This damage is probably caused by the variation of loading conditions (pressure, sliding velocity and abrasive shape) during unloading of the granular material [1]. So, manufacturing process is often specified to be capable of meeting the critical function requirements in terms of reduced frictional losses and minimal wear.…”

This study intended to investigate the effect of tribological parameters on wear mechanisms and friction coefficient for homogeneous and heterogeneous materials. Particularly, effects of particle geometry and normal load on the tribological behaviour of an aluminium alloy and nodular cast iron have been developed. These materials are used in two industrial applications. The first one is used to transport granular material. It has been shown that damage of used truck's buckets is produced. However, the nodular cast iron is used in automobile industry thanks to its lower density, good wear resistance and its low friction coefficient. A scratch test was used and the wear mechanisms were observed for different attack angles. The normal load was also varied and correlation between wear mechanisms, tribological parameters and friction coefficient was highlighted.

For the 7xxx aluminum alloy, interaction between grooves induces the transition of wear mechanism from ploughing and wedge formation to cutting.…”

Abstract. The aim of the present paper is to study aluminum alloy behavior against single and multi-indenter scratch tests. An experimental device was designed. Scratch test, using a steel conical indenter, was carried out at a constant sliding velocity of 210 mm/min. First of all, the influence of tribological parameters on apparent friction coefficient was investigated. Four attack angles of 10, 30, 45 and 60° are selected. The normal load was varied from 10 to 25N by increment of 5N. Moreover, the study of the wear mechanisms by microscopic observation has been conducted. It has shown that tribological parameters have an essential influence on the apparent friction coefficient and wear mechanism. Then correlation between tribological parameters and wear mechanisms has been highlighted. This correlation allowed elaborating a map wear for both single and multi-indenter scratch tests. Finally, comparison between single and multi-indenter scratch test has been performed in order to understand the effect of interaction between scratches.
