Structure formation and tribological properties of bronze-Fe composite materials produced by electron beam additive manufacturing
摘要
The paper investigates the microstructure and properties of composite materials based on aluminum-manganese bronze and stainless steel. It is demonstrated that the microstructure has an effect on the tribological behavior of aluminum-manganese bronze–steel composites under dry friction and boundary lubrication conditions. The tribology testing results indicate a catastrophic wear of composites. The increased steel content in the bronze matrix leads to a dramatic growth in the wear intensity during the dry friction due to the enhanced adhesive interaction between the counter body and the sample. Tribology testing at the boundary lubrication shows an acceptable tribological performance and a moderate wear rate for the composite materials.
