“…This effect is probably attributable to the greater ability to retain lubricant in the pockets (see Table 4), due to the increase in the void volume parameter, Vvv, as the EDT texture degree increases (see Figure 8). The importance of the functional volume Vvv parameter has also been previously discussed by Ruimin et al [57].…”

The increasing demands for lightweight design in the transport industry have led to an extensive use of lightweight materials such as aluminium alloys. The forming of aluminium sheets however presents significant challenges due to the low formability and the increased susceptibility to galling. The use of tailored workpieces and controlled die roughness surfaces are common strategies to improve the tribological behaviour, whilst galling is still not well understood. This work is aimed at analysing the interplay between the sheet and tool surface roughness on the friction and galling performance. Different degrees of Electro Discharge Texturing (EDT) textures were generated in AA1050 material strips, and tooling presenting different polishing degrees were prepared. Strip drawing tests were carried out to model the tribological condition and results were corroborated through cup drawing tests. A new galling severity index (GSI) is presented for a quick and quantitative determination of both galling occurrence and severity. The present study underlines the key role of die topography and the potential of die surface functionalization for galling prevention.

The objective of this work is to identify the most influential parameters on the friction coefficient and wear rate, using the response surface method. The friction tests were carried out by adopting the methodology of complete planes 23at three factors ("D", "V" et "Py"), at two level for each factor. The results show a decrease in the wear rate when the three factors are at their highest level and a decrease in the friction coefficient when using minimum loads and speeds on important distances. In addition, the developed mathematical models make it possible to reveal a correlation between the test parameters and the responses studied in their studied domain. An evaluation of the volume parameters "Vmc" and "Vvv" was carried out. The morphology of the worn surface shows that the friction under a load of 1 N leads to the predominance of an abrasive wear mechanism, while a load of 10 N favors an adhesive wear mechanism, increasing the parameters "Vmc" and "Vvv" to the maximum.

This paper presents a test device to explore the influence of geometric attribute of the contact surface on friction coefficient along with sliding speed and contact pressure. Friction tests were conducted on a third-generation high strength steel QP980. The friction coefficients for different surface curvatures, contact pressures and sliding speeds were calculated and the influences of these factors were analyzed. The formula for calculating the friction coefficients between curved contact surfaces was derived. The relationship between bending induced surface roughness increase and friction coefficient was established. An enhanced friction coefficient model with pressure, velocity and curvature dependence was proposed. The enhanced friction model was applied to simulate the stamping of an automotive part and a better correlation was achieved.
