WebSo, erosion wear behavior can be grouped as ductile and brittle categories with respect to impingement angle. The ductile behavior is characterized by micro-plowing, particularly in metal where maximum erosion takes place at low impact angles (15–30-degrees). However, in brittle materials, maximum erosion takes place at normal impact and ...
