摘要: Abstract In this study, the solid-particle erosion behavior of carbidic austempered ductile iron (CADI) containing different amounts of ceria nanoparticles was investigated. Attempt made to correlate erosion resistance material its microstructure and mechanical properties. It demonstrated that CADI improved by adding nanoparticles. The maximum rate unmodified occurred at impact angle 60–75°, which slightly shifted lower angles when were added, corresponding more characteristic. During tests, retained austenite in partially transformed martensite although transformation suppressed addition ceria-modified showed a considerably increased various angles.
