Effect of Aluminum on Mechanical and Frictional Properties of Copper Cladding Iron-Based Braking Material

Abstract

Fe-20wt%Cu-Al braking materials were prepared by induction heating sintering method combined with the Copper cladding iron matrix with various aluminum elements. Effects of Aluminum on surface morphology, Mechanical and frictional properties of Cu-Fe-based Braking Material were analyzed by Scanning Electron Microscope (SEM), machine test and friction-wear test. Lastly suitable parameters of the process are decided. Meanwhile, wear mechanisms were discussed. The results showed that the prepared shaking materials with aluminum content of 3wt%, silicon carbide content of 5wt%, manganese and chromium content of 5wt% and copper cladding iron power content of 87wt% had excellent performance.
