Current position at VTT
Research Professor (Machine operability – tribology, condition monitoring and diagnostics)
Research background and current research topics
His current research focus is on tribology, surface coatings, wear modelling and simulation, biotribology and e-maintenance.
He started tribology research in 1978 with investigations on boundary lubrication effects of macrotextured surfaces in sliding and rolling contacts. It was followed by investigations of wear of steel and ceramic surfaces as well as wear particle monitoring. The last twenty years he has intensively studied the friction and wear mechanisms of surfaces coated by very thin, about one micrometre thick ceramic surface coatings such as physical and chemical vapour deposited surfaces. His research group presented a structure to classify the friction and wear mechanisms of thin coatings on different scale levels from nano to macroscale.
They combined fracture mechanics, FEM modelling and tribology contact mechanism analysis to successfully model TiN, DLC and MoS2 coated steel surfaces, simulated the stress and strain pattern, investigated different surface parameter effects and published a generic wear equation. The present focus is to study composite coated surfaces by multiscale modelling techniques in a number of projects connected to industrial R&D challenges. He is presently coordinating the strategic computational materials modelling and simulation research.
Simultaneously he has been involved in machinery condition monitoring, diagnostic and prognostic research. Recently he coordinated a large European research team that developed and demonstrated in industrial environment the pioneering e-maintenance concept DynaWeb.
He has authored and edited several books, given 41 invited keynote lectures at international conferences and published more than 170 scientific papers.
