The failure mechanisms of tribologically stressed materials, which are also in contact with highly corrosive fluids, are at present not definitely distinguishable, or in other words, the time of failure is not predictable. In particular, the equipped carbon steel materials, which differ in their microstructural composition, are more or less varying. The lack of knowledge in this field is resulting in high costs of materials and maintenance due to the undefined failure probability of the materials. The aim of the present work is the characterization of tribological and corrosive effects on commonly equipped steel materials in contact with a nickel base counter body. A correlation between abrasive and corrosive effects under tribological stress, the chemical composition of the materials and the corrosive medium, the microstructure and the heat treatment process of the equipped materials are the topics of these investigations. The conditions predominant in practical applications are simulated in lab-scale experiments. Further on, a test principle was established in order to investigate the influences of wear and corrosion under CO2 conditions simultaneously. With this system, the differences between a ferritic/pearlitic and a martensitic steel sample were investigated and also compared to the results for the tribological and corrosive tests. The sliding corrosion test rig shows a good comparability and therefore offers a high potential as wear tester under corrosive conditions.
