Abstract

Abstract Materials exposed to severe environments during their service are displaying significant, unwanted surface changes. The study of erosion and abrasion has a complex nature and is recently the focus of interest due to its industrial sector significance (e.g. aerospace, maritime, oil, gas). Erosion, abrasion and hardness testing are aiming to predict materials behavior working in harsh environmental conditions in order to optimize their selection. This project was introduced as a technical elective/independent study class in mechanical engineering. Undergraduate students have the possibility to work directly and gather experience with existing equipment in Mechanical Engineering Department: erosion, abrasion, hardness testers, heat treatment furnaces, magnetron sputtering equipment and profiler. Students are planning their activities and are guided to use the appropriate equipment for testing. The study involves mechanical testing of multiple materials, analyzing and deriving correlations between erosion, abrasion, and hardness results. The materials used for testing are: coated and uncoated metallic materials (4140 steel, tool steel, stainless steel and aluminum alloys) and polymers (e.g. polycarbonate (PC), polyvinyl chloride (PVC), high density polyethylene (HDPE), high impact polystyrene (HIP), polypropylene (PP) and epoxy). Students recognize the industrial importance of erosion and abrasion processes, become aware of the associated real-life problems and foster the use of theoretical knowledge gathered in other engineering classes for practical applications. Students are working together as a team towards meeting the deadlines and for preparing and presenting their results at professional conferences.
