Abstract

The paper describes an examination method of polymer coatings erosive wear and the results of the examination carried out using this method. It consist in free falling of erosive material onto examined coating and measurement of wear scar. Intensity of coating erosive wear is, among others, proportional to erosive particles impact energy in the moment when they hit the coating. The different impact energies can be obtained differentiating the height of free fall. The examination concerned influence of coating modification with nanofiller on its resistance to erosive wear. Obtained results clearly reveal that this kind of modification gives positive effect decreasing coating erosive wear intensity.
