• An experimental study was conducted to assess the scratching abrasion in dry and wet environments on X-70 steel and five different types of titanium carbide particulate polyurethane composites (PU). A testing apparatus was constructed based on the dry sand rubber wheel test method standardized by the American Society of Testing and Materials (ASTM). The major focus of attention was given to wet abrasion testing of these materials with either a rubber wheel or a steel wheel. The influence in wear behavior of PU due to their moisture content and steel wheel roughness was also addressed. In addition, wet abrasion experiments under low dissolved oxygen conditions were conducted on X-70 steel to isolate erosion effects under wet conditions. Wear mechanisms in the materials under study were assessed through scanning electron microscopy analysis. In general, wear mechanisms such as cracking, pluck-out and indentations were observed with more or less severity
