摘      要：The work in this study is focused on the investigation of the structure and properties of ductile cast iron with nanoparticle additives： TiN （titanium nitride）, TiN ＋ TiCN （titanium carbonitride） and cBN （cubic boron nitride）. The nanoparticles are coated with nickel prior to addition to the iron melt to improve their wetting and uniform distribution in the volume of the casting. The metallographic observation and wear test are performed to study the influence of the nanoparticle additives on the microstructure and and cast iron tribological properties.
