At elevated temperatures, oxide scales can form on the stressed surfaces forming so called glazed oxides. The glazed oxides prevent direct contact between the rubbing surfaces. In this case, the wear is significantly reduced.
At the DECHEMA Corrosion Center, wear and friction investigations can be conducted from room temperature up to 800°C using various friction partners ( Al2O3, steel, WC etc., pin-on-disc) in a linear or rotational set up. Furthermore, wear tests can be conducted in a liquid environment at room temperature.
