Erosion resistance of ductile cast iron

Particle erosion is wear loss from surface of solid body because of relative motion of fluid with solid particles. Erosion where are impact angle is small (less than 30°) is abrasive erosion and erosion where are impact angle is big (60° do 90°) is impact erosion. One of the advantages of ductile cast iron in relation to other cast irons is his good wear resistance. However, we must considered that wear resistance depend of wear condition. Solid particle erosion resistance is function of impact angle. Results of testing show that abrasive erosion resistance (impact angle 15°) is much better than impact particle erosion (impact angle 90°).
