“…The cavity size is greatly influenced by irradiation parameters and substrate materials, with diameters ranging from several microns [30] to tens of microns [15,25,26,28,31,32], even to a few hundred microns [6,29], and depth from a few microns [26,29,32] to tens of microns [24]. The amount of cavities is intimately dependent on the HCPEB pulse number [6,8,12,24,[27][28][29][30]32] and energy density [29,30,33]. In particular, the presence of crater-like cavities makes the irradiated surfaces resemble textured ones from the viewpoint of tribology [27,28,[30][31][32].…”
