- ItemChemical Bonded PA66-PTFE-Oil Composites as Novel Tribologically Effective Materials: Part 2(London [u.a.] : Institute of Physics, 2021) Nguyen, Thanh-Duong; Kamga, Lionel Simo; Gedan-Smolka, Michaela; Sauer, Bernd; Emrich, Stefan; Kopnarski, Michael; Voit, Brigitte; Karjust, Krist; Otto, Tauno; Kübarsepp, Jakob; Hussainova, IrinaPolytetrafluoroethylene (PTFE) exhibits excellent non-stick properties and a very low coefficient of friction under tribological stress, but it is incompatible with almost all other polymers. In the first part of this study we presented the generation of the novel tribological material based on unsaturated oil, radiation-modified PTFE (MP1100) and Polyamide 66 (PA66). To get a better understanding of the chemical properties and chemical composition of the compounds, the PA66-MP1100-oil-cb (chemical bonded) compounds were examined by differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). In this part, the mechanical properties of the compounds are compared with plain PA66 and PA66-MP1100-cb. The tribological investigation was carried out using the Block-on-Ring tribometer. It was found that the mechanical properties of PA66-MP1100-oil-cb with 20 wt.% MP1100-oil-cb only show slight differences compared to PA66, but the tribological properties of the compounds have been significantly improved through chemical coupling between the three components. Finally, the amount of the compound that was deposited on the surface of the steel disc counterpart was analyzed after the tribological testing.
- ItemDevelopment of a Metal-Based Lightweight Approach Consisting of Cold-Formable Magnesium Sheets in Combination with a Multi-Purpose Powder Coating System(Basel : MDPI, 2022) Victoria-Hernández, José; Scholz, Peter; Vakulenko, Serhii; Gedan-Smolka, Michaela; Tuschla, Marcel; Letzig, Dietmar; Kwiatkowski, LechThis paper will give an overview about the development of a material system, which consists of a novel formable magnesium alloy that is provided with an effective corrosion protection coating. The corrosion protection is to be realized in the form of a forming stable powder coating, which can be applied in the coil coating process. To improve the tribological properties, additional additives are added to the powder coating. Within this paper, first results concerning tribological and forming behavior of the new lightweight material system are given. For the benchmark, the results are compared with commercially available AZ31 Mg alloy.
