Sliding wear behavior of Cr-Mo-Cu alloy cast irons with and without nano-additives

- The nano materials were used to modify the performance of alloy cast iron.
- The hardness of alloy cast iron with nano-additives increased greatly.
- The wear resistance of alloy cast iron with nano-additives increased notably.
- The grinding efficient of alloy cast iron with nano-additives was dramaticlly better than that of alloy cast iron without nano-additives.
