The same morphology images were analyzed as well from a statistical point of view. After computing the GLCM matrix for each image, the energy and correlation parameters were extracted for different pixel distances (1, 10, and 100 pixels) in each image. The results are summarized in Table . The energy values of the surface morphology GLCM matrix (Table ) do not have great variations based on the pixel distance, but they do vary based on power supply type and deposition time. For the DC power supply, the energy increases with deposition time and for the HiPIMS power supply, the energy decreases with deposition time. This means that the layer deposited using the DC power supply becomes smoother as the deposition time increases while the layer deposited using the HiPIMS power supply becomes rougher.
