Mirosław Szala works at the Department of Materials Engineering, Mechanical Engineering Faculty, Lublin University of Technology, (Poland). He is Focused on Surface Engineering and Metal Surface Treatment for the manufacturing of wear-resistant materials, especially in the application of cavitation erosion-resistant coatings. Moreover, Mirosław is interested in the abrasion, erosion and sliding wear prevention of engineering materials, and investigation of the technologies application for minimalising the deterioration of metal-based structures. The current object of his study are thermally sprayed coatings, magnetron sputtered PVD hard films, and Ni-, Co- and Fe- based weld paddings and MMCs. He investigates the effect of mechanical, structural and surface layer properties on wear resistance as well as studying phenomenological mechanisms affecting cavitation erosion of solid structures. Additionally, he is an active certified welder and hi likes spending his free time playing electric guitar or jogging.

Presentation title:

Surface engineering vs. cavitation erosion resistance - the technologies reducing of materials degradation.

Abstract:

The presentation describes the results of broad studies of the cavitation erosion behaviour and phenomena responsible for coatings and metallic materials resistance. Cavitation erosion is a unique wear process that still is not entirely understood. Even though the literature on the subject explains the general factors influencing cavitation erosion of materials, the continuous development of metal-based structures fabrication, processing, and treatment technology demands systematic reporting on the advances in the wear properties of metallic materials. From both the scientific and engineering points of view, the wear of metallic components must be minimized to improve their reliability. The engineering industry is demanding metal-based structures that perform well in terms of cavitation erosion. First, to manage that task, material wear mechanisms should be understood. To facilitate the selection and design of wear-resistant materials, computer simulation, numerical calculations, or artificial neural networks can be employed. The presentation is focused on the cavitation erosion testing of metal-based structures, hardfacings, thermally sprayed deposits, thin films, composites. The cavitation wear improvement via microstructural properties modification, surface layer treatment, and the deposition of wear-resistant coatings onto a metal-based substrate are described.
