We carry out theoretical and experimental investigation of the tribological performance, damage, and failure mechanisms of monolithic or composite material systems and products subjected to friction and wear.
COMPETENCIES
• Revealing the problems of operational structures subjected to wear, exploring the causes of the wear damage, expert analysis
• Supporting material and technology developments aimed at increasing the tribological performance, reliability, and lifetime; carrying out and evaluating the necessary theoretical and experimental investigations
• Investigation of surface-modified gradient and heterogeneous material structures, substrate-coating material systems, tribological characteristics of thin films with the aim of increasing the reliability and service life, and technology optimisation
SERVICES
• Characterisation of tribological performance by means of surface mechanics and microstructural investigations, e.g., dry and lubricated wear test, instrumented scratch test, Calotest, hardness test and microscopy; determining quantitative characteristics (adhesion, static and dynamic friction coefficient, worn volume, etc.) and qualitative features (wear mechanisms, wear morphology) of the tribological performance
• Determination of general roughness characteristics, analysing microtopography influencing the friction and wear behaviour; revealing the correlation between these features and tribological characteristics
• Modelling and simulation of damage processes, contact and friction problems of material systems and products (e.g., engineering components, tools) exposed to wear
• Measurement of substrate-free nanohardness and modulus values of coatings
• Education and training on topics related to design, operation, qualification, damage analysis, and material testing of structures subjected to wear
