Light weight design offers a lot of interesting manufacturing and operation aspects in mechanical engineering, e.g. concerning production and material cost or energy consumption. By means of protective coatings, light metal components can also be used under extreme wear and corrosion conditions. Of tribological interest are coating systems with low friction and wear coefficients. If traditional liquid lubricants cannot be used, the tribological functions must be taken over by material surfaces with solid lubricant capability. Very promising tribological results under dry and mixed friction are obtained by thermally sprayed TiO2 coatings. The paper presents a general overview about the tribological and mechanical properties of APS and HVOF sprayed TiO2 coatings on different light metal materials.
