New wear protection systems, intended for use especially against fine and extremely abrasive dusts

Wear and tear on machines and plants results in billions of euros worth of damage yearly. Together with the ISAF, Technische Universität Clausthal, Clausthal-Zellerfeld in Gemany and the company DURUM, Venti Oelde has been conducting experiments to ensure that, when high-grade steels are being hardfaced, an effective wear protection is provided and also that the mechanical properties of the original base material are retained improved. The article describes hardfacing high-grade steels using the controlled dip transfer (short arc) welding process. The mechanical properties of the base steel as well as the behavior of the applied wear protective layers were analysed.
