Tysiąclecia Państwa Polskiego 7, e-mail: b.antoszewski@tu.kielce.pl Key words: friction, laser texturing, lubrication Abstract In this paper, a Nd:YAG laser was used to generate micropores on SiC surface and the structure and morphology features of surface micropores were observed. Tribological experiments were conducted with pin-on-disc tester under various loads and speeds. The article concentrates on identification of friction processes and also attempts to find a correlation between surface energy, friction force and topography of surface with geometrical texture. Introduction heat removal, vaporization, wettability, biological functions, absorptivity, etc. Energy losses resulting from friction between Reference [2] compares results of tribological contact surfaces in an internal combustion engine tests conducted by means of pin-on-disk devices, have been studied intensively by a considerable where the disk surfaces were polished, ground and numbe
