Title: Wear behavior of austempered ductile iron with nanosized additives
Keywords: Nanosized particles, Austempered ductile iron, Hardness, Wear resistance

Abstract: The microstructure and properties of austemperedductile iron (ADI)strengthened with nanosized addtives of titanium nitride + titaniumcarbonitride (TiN + TiCN), titanium nitride TiN andcubic boron nitride cBNare investigated.The TiN, TiCN and cBN, nanosized particles are coated byelectroless nickel coating EFTTOM-NICKEL prior to the edition to the melt. Thespheroidal graphite iron samples are undergoing anaustempering, includingheating at 900оС for an hour, after that isothermal retention at280оС, 2 hand 380оС, 2h. The metallographic analysis by optical metallographicmicroscope GX41 OLIMPUS and hardness measurements by Vickers Methodare performed.The structure of the austempered ductile iron consists of lowerbainite and upper bainite.Experimental investigation of the wear by fixedabrasive are also carried out. The influence of thenanosized additives on themicrostructure, mechanical and tribological properties of the austemperedductile irons (ADI) is studied.
