EN Particle erosion is a wear loss from surface of solid body caused by a relative motion of fluid with solid particles. When impact angle is low (between 0 degree and 30 degree), this kind of erosion is called the abrasive erosion. On the other side, if the impact angle is between 60 degree and 90 degree, it is considered the impact erosion. One of the advantages of ductile cast iron in relation to other cast irons is its good wear resistance. However, we must consider that wear resistance depends on conditions of wear. Particle erosion resistance is a function of an impact angle and a kind of erosion particles. In this paper, samples of ductile cast iron were eroded with steel balls of two different sizes at six different angles of impact (15 degree, 30 degree, 45 degree, 60 degree, 75 degree and 90 degree). Test results were presented as a loss of mass, which occurred during the test. Wear scars were analyzed by scanning electron microscope. Test results showed that ductile cast iron had a higher abrasive erosion resistance (impact angles 15 degree and 30 degree) comparing to its impact erosion resistance (impact angles 60 degree, 75 degree and 90 degree). The angle of 60 degree had a maximum measured wear.
