Enhancing tribological performance of Cu-1Cr-0.15Zr alloy through optimized processing routes
This study explored the mechanical and tribological properties of Cu-1Cr-0.15Zr alloy processed through various routes. Aged + cryo-rolled sample (ACTR) exhibited the highest hardness and strength, solution treated + aged (STA) the highest ductility, and two-step cryo-rolled + aged (CTRACTRA) the hi...

| Summary: | This study explored the mechanical and tribological properties of Cu-1Cr-0.15Zr alloy processed through various routes. Aged + cryo-rolled sample (ACTR) exhibited the highest hardness and strength, solution treated + aged (STA) the highest ductility, and two-step cryo-rolled + aged (CTRACTRA) the highest deformation energy. TEM analysis revealed cellular dislocation structures and Zr-rich precipitates but no twins. Wear testing revealed that aging before cryo-rolling (ACTR) significantly improved tribological performance. The ACTR sample consistently showed the lowest wear rate and friction coefficient across all applied forces. Increasing sliding distance also impacted wear more than increasing load. SEM analysis indicated adhesive wear as the dominant mechanism. Oxidation was also observed at low forces and short distances for CTRACTRA and ACTR. |
