| Abstract: |
Cu-Cr-Zr alloys have excellent electrical and thermal conductivity. So, these alloys possess major contribution to industrial applications which were fabricated with the help of the laser powder bed fusion (LPBF) technique. However, during the printing process, the geometries were affected by cavity formation, poor wettability between the particles, etc. In this study, LPBF parameters such as laser power (300, 350 and 400 W), exposure time (200, 300 and 400 µs) and overlapping rate (10, 30 and 50%) were examined to prepare a fully dense part with minimum defects. Parameters evaluated for the combined influence of process parameters were relative density, nanohardness and surface roughness. The effects of different combinations of input parameters on defect formations and micropores were also demonstrated. Furthermore, observations from 2D scanning probe microscopy (SPM) images and 3D topography were used to evaluate the surface roughness. The combination of 400-W laser power, 300-μs exposure time and 50% overlapping rate has led to highly dense parts with a reduced surface roughness of 11.32 µm and also with maximum reduced modulus and nanohardness of 191.4 and 5.8 GPa.
