Investigation of structural, electrical and tribological properties of duplex surface treated and aged Cu-Cr-Zr alloyUntersuchung der strukturellen, elektrischen und tribologischen Eigenschaften einer duplex-oberflachenbehandelten und gealterten Cu-Cr-Zr-Legierung

In this study, Cu-Cr-Zr alloy specimens were first subjected to aging heat treatment at 500 degrees C for two different durations (2 hours and 4 hours). Three different coating processes (silver, silver/copper duplex, and copper/silver duplex) were applied to the aged specimens using the physical vapor deposition method. Tensile test, microhardness measurement, wear test, electrical conductivity measurement and structural analysis (x-ray diffraction and scanning electron microscope) were applied to the specimens. After the aging processes, the highest hardness and strength values of the Cu-Cr-Zr alloy were obtained in the specimens that were aged at 500 degrees C for 4 hours. When the wear resistance and electrical conductivity of the coated specimens were examined, it was determined that the specimens with duplex surface treatment performed better.

Automated summary

In this study, Cu-Cr-Zr alloy specimens were subjected to aging heat treatment at 500 degrees C for different durations. Three different coating processes were applied using physical vapor deposition method. The specimens were then tested for mechanical properties, wear resistance, electrical conductivity, and structural analysis. The results showed that the specimens aged for 4 hours at 500 degrees C had the highest hardness and strength values. Furthermore, the specimens with duplex surface treatment exhibited better wear resistance and electrical conductivity.
