Correlation Between Tribological Parameters and Wear Mechanisms of Homogeneous and Heterogeneous Material

Abstract

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.

Effect of a combined machining/burnishing tool on the roughness and mechanical properties

“…Microhardness measurements in the subsurface cross section proved that the work‐hardened layer obtained after the combined process is about 350 µm thick. These results confirm the tribologically transformed structure formation already mentioned in other situations …”

“…These results confirm the tribologically transformed structure formation already mentioned in other situations. [25][26][27] Analysing the microhardness and the residual stress evolution versus depth is first noted that the machining has no significant effect on microhardness. However, the combined process affects the under layer microhardness, and a subsurface work hardening phenomena are observed.…”

Electroplated Nanocomposites of High Wear Resistance for Advanced Systems Application

“…The amount of particles in the coatings affects the wear rate. The friction behaviour of multiphase materials has been described in the literature Mezlini and et al, 2009). The main problem with these approaches is that they are static ones and applied to ideal surfaces because during wear of a multiphase material the topography changes in practice continuously.…”

A micromechanical scratch model to investigate wear mechanisms in UD-GFRP composites

“…The study of the surface integrity, particularly of the composite material requires in-depth knowledge of the abrasion tests which spotlight the local surface properties and contact behavior, including friction, adhesion and damage. The most used technique in characterization of both homogeneous [1] and heterogeneous [2,3] materials friction behavior is the scratch test.…”
