- Abstract
The production processes of the metalworking industry are usually carried out in the presence of oxygen. Particularly due to surface oxidation on tools and parts during production under normal atmosphere, high wear is observed in tribological systems. The focus of these investigations is the question to what extent the ambient atmosphere has an influence on the tribological system. For this purpose, the identification and characterization of wear mechanisms in an oxygen-free atmosphere is of high relevance. To analyse the influence of the ambient atmosphere on the tribological properties of titanTum, ball-on-disc investigations are carried out on a universal tribometer (UMT) in an air, argon and silane-anodized atmosphere. By suppressing the oxidation under exclusion of oxygen, a reduction of the tribochemical wear could be shown, which is accompanied by a reduction of the wear volume by a Factor of 4.5. However, due to the adhesion of both friction partners, which already occurs at low temperatures, caused by the omission of the friction-reducing cover layers, the friction coefficient increased. In addition, novel alloy formations at the interfaces were detected and analysed.
