Erosive wear of machine elements is the process of significant complexity with crucial role played by mechanical properties of contacting materials. For this reason the process of erosive wear shows different progress for metallic machine elements with polymeric coatings than for elements without them. An estimation of erosive wear process dynamics of epoxy coatings is presented in the paper. On the ground of examination results it was stated that kinetics of erosive wear depends on: erosive particles velocity, their concentration and impact angle as well as micro- and macrostructure of the coating. The microcutting of coatings was dominant process of examined coatings wear and its biggest share was observed for impact angles alpha < 30o. However the participation of fatigue spalling of coating material, preceded by its plastic deformation, was increasing with increase of erosive particles impact angle. Mathematical model of erosive wear process of construction element surface describes effectively kinetics of this process in dependence on: erosive particles impact angle, their concentration and velocity in the moment of impact. Using of finite elements method allowed for effective predicting of surface profile shape of polymer coatings subjected to the erosive particles influence.
Zużywanie erozyjne elementów maszyn jest procesem złożonym, w którym znaczącą rolę odgrywają własności mechaniczne kontaktujących się materiałów. Dlatego też proces ten zupełnie inaczej przebiega w przypadku elementów metalowych z powłokami polimerowymi niż w przypadku elementów bez tych powłok. W artykule dokonano oceny dynamiki procesu zużywania erozyjnego powłok epoksydowych. Na podstawie wyników badań stwierdzono, że kinetyka tego procesu zależy od: prędkości cząstek erozyjnych, ich koncentracji oraz kąta padania, a także mikro- i makrostruktury powłoki. Dominującym procesem zużywania badanych powłok było mikroskrawanie, którego największy udział obserwowano dla wartości kąta padania alfa < 30°. Natomiast udział wykruszania zmęczeniowego materiału powłoki, poprzedzanego jego odkształcaniem plastycznym, zwiększał się wraz ze wzrostem kąta padania cząstek erozyjnych. Model matematyczny procesu zużywania erozyjnego powierzchni elementów konstrukcyjnych opisuje efektywnie kinetykę tego procesu w zależności od: kąta padania cząstek erozyjnych, ich koncentracji i prędkości w chwili uderzenia. Zastosowanie metody elementów skończonych umożliwiło efektywne prognozowanie kształtu profilu powierzchni powłoki polimerowej poddawanej oddziaływaniu cząstek erozyjnych.
