“…Similar reported observation is given in Wang et al 51 With regard to brass, there is no much work seen in the literature. 29 In Amirat et al, 29 the wear data is not available; however, the observation on the worn surfaces have been reported showing a clear abrasive nature on the surface, which is in high agreement with the current work.…”

Understanding the wear mechanism significantly contributes to the knowledge of tribology of common metals and assists in predicting, overcoming and preventing the failure of designed components. In the current study, wear and frictional performances of brass, aluminium and mild steel metals are investigated at different operating parameters, i.e. sliding durations (0–10 km) and applied loads (0–50 N) against stainless steel counterface under dry contact conditions. The experiments were performed using block on ring machine. To categorise the wear mechanism and the damage features on the worn surfaces and the collected debris, scanning electron microscopy was used. Thermal imager was used to understand the heat distribution in the contacted bodies and the interface regions. The results revealed that the operating parameters influence the wear and frictional behaviour of all the metals. Brass metal exhibited better wear and frictional behaviour compared to others. Three different wear mechanisms were observed, i.e. two-body abrasion (brass), three-body abrasion (aluminium) and adhesive (mild steel).

A Stress-Criterion-Based Model for the Prediction of the Size of Wear Particles in Boundary Lubricated Contacts

In this paper, the formulation and validation of a model for the prediction of the wear particles size in boundary lubrication is described. An efficient numerical model based on a well-established BEM formulation combined with a mechanical wear criterion was applied. The behavior of the model and particularly the influence of the initial surface roughness and load was explored. The model was validated using measurements of the wear particles formed in steel-steel and steel-brass contacts. In the case of steel-steel contact, a reasonable quantitative agreement was observed. In the case of steel-brass contact, formation of the brass transfer layer dominates the particles generation process. To include this effect, a layered material model was introduced.

“…In industrial applications, graphite is more used as a solid lubricant when it is impossible to use a fluid lubricant and graphite has good tribological qualities due to its particular structure. 6,15–24 However, graphite remains less adaptable in high temperature applications since it is highly sensitive to the humidity and to the surface desorption phenomenon. 5,23–26…”

Some industrial applications require the use of self-lubricating materials when fluid lubrication cannot be used. Carbon-based materials and in particular graphites are usually a used solution. However, the application of these materials is limited at high temperature; these materials are exposed to significant degradation and to high friction due to their high sensitivity to the air humidity and to the desorption phenomenon. This study determines the influence of a specific metallic impregnation on the graphite bearing, which is submitted to a severe thermo-vibratory loading by fretting against a stainless steel surface. The stainless steel surface has undergone a nitriding treatment by plasma. During the fretting contact, a strong transfer of the impregnant takes place from the impregnated graphite bearing to the steel conterface by adhesion; this deposit film allows a significant improvement in the tribological properties of the contact surfaces at high temperature.
