Microstructure, Microhardness and Tribological Properties of Bronze-Steel Bimetallic Composite Produced by Vacuum Diffusion Welding.

In this paper, a lead-bronze/steel bimetal composite was produced by vacuum diffusion welding technology. The microstructure, hardness and tribological properties under the dry sliding condition of the bimetal structured material were investigated and compared with two reference samples, i.e.
