Objective Various components of transportation systems and automotive applications require liquid lubricants to reduce friction by separating surfaces from each other. Nevertheless, dry friction may occur during the starting procedure or when liquid lubricant is lost. Therefore multifunctional surfaces are necessary for improved wear and friction behaviour and to increase life and overall efficiency of machinery parts. Coating technologies, and particularly thermal spraying, offer a wide variety of materials for forming surfaces with the desired properties. Using agglomerated micropellets or mechanical blends of ceramic or metal matrix material with self-lubricant particles, multicomponent coatings can be obtained showing improved friction behaviour.The objective of this project is to improve the tribological behaviour of thermal sprayed coatings by self-lubricant reinforcement. The main areas are powder production, coatings generation and evaluation particle of the coatings. The basic materials will be ceramics (Cr203) and pure metals (Mo). As self-lubricant additives MoS2, BN and CaF2 will be chosen. The feedstock material for thermal spraying will be produced by mechanical blending or self-propagating synthesis. Different ratios of matrix material and self-lubricants will be prepared. As coating methods, different thermal spray will be selected. Atmospheric plasma spraying will be compared with high velocity oxygen fuel spraying. The coatings achieved will be evaluated with regard to friction and wear resistance. Modern test advices such as ball-on-disk will be carried out under various conditions (load, atmosphere) in order to analyse the friction coefficient. A significant characteristic for the coatings quality is the coefficient (COF.). This value will be determined on the generated coatings in a pin-on-disk wear test device.
