Submicron scale experimental analyses of the real contact area for different topographic and material properties [Elektronski vir]Brodnik Žugelj, Blaž ; Kalin, MitjanIn conventional engineering approach, contact conditions are calculated with the assumption of nominal contact area between two surfaces, which is greater than actual contact area. Consideration of ... such assumptions leads into calculations of milder contact conditions as they appear in real. Actual conditions within engineering contacts strongly depend on load, topographic parameters and material properties of contacting surfaces. In this study we analysed how relevant engineering roughnesses (i.e. Ra 0.1 % 1.0 %m) and different materials (i.e. steel, aluminium and POM polymer) influence the actual behaviour of multi-asperity contacts. Namely, contact pressure, deformation of the asperities and real contact area were analysed experimentally. Results were obtained with the newly developed test rig, which enables direct and in-situ investigation of the real contact area with submicron resolution. The results indicate that at the same Ra roughness analysed metals exhibit similar contact behaviour despite the wide range of material properties. On the other hand, polymer behaves differently from steel and aluminium. For example, at yield stress the real contact area for POM is up to 7-times larger than in the case of metals. Furthermore, results indicate that contact behaviour for POM is almost independent of the Ra roughness.Source: ECOTRIB 2017 [Elektronski vir] (PDF datoteka (1 f.))Type of material - conference contributionPublish date - 2017Language - englishCOBISS.SI-ID - 15587355
