Sažetak
Ductile cast iron has high fatigue strength due to the spherical shape of graphite, especially after quenching and tempering. Higher toughness can be achieved by austempering. One of the advantages of ductile cast iron in relation to other cast irons is its good wear resistance. In the experiments, samples of ductile cast iron and austempered ductile cast iron were eroded with quartz sand particles at six different angles of impact (15°, 30°, 45°, 60°, 75° and 90°). The test results were presented as the loss of mass which occured during the test. Testing with quartz sand shows that the particle erosion resistance of ductile cast iron was better than that of austempered ductile iron for all impact angles except for 60°. The maximum measured wears of ductile cast iron and austempered ductile iron were at 75°.
