Abstract

Corrosion and wear – these terms stand for a range of topics which in industrial practice cause many problems and cost. The lifetime of the machine or apparatus – and in connection with it the maintenance cost, often depends on the life of a single component which is subjected to strong corrosion and increased wear. Therefore, the feasibility and profitability of certain production processes are closely connected to the question of whether the existing wear problems have been successfully solved.

In the following we concentrate on a section of the wide field of chemical apparatus engineering, namely on conveying gases and fluids. If the media exhibits corrosive properties and contains abrasive particles, extreme demands are put on the wear resistance of components directly in contact to the media, e.g. mechanical seals, sliding bearings, and rotating shaft sleeves.
