The work presents the preliminary test results concerning the texturing process for friction pairs with flat surfaces. The Nd:YAG laser was applied to treat SiC face seal rings with the following dimensions do = 35.3 mm, di= 25.1 mm and h = 8 mm. The series of homogeneous textures obtained during the experiments differed in the diameters of cavities (70-150 žm) and the distances between the centres of symmetry axes (106-279 žm). The depth, g, was constant: 15 žm. A procedure was developed to select technological parameters for the texturing process. The experiments included a microscopic analysis of the whole unit and single craters as well as tribological tests using a T-01M pin-on-disc tester. The theoretical analysis focused on such aspects of texture in friction pairs as a change in contact surface and contact load and physical relationships between the lubricating liquid and the textured surface. The results of the preliminary tribological tests show the suitability of the method applied and the efficiency of the texture of friction pairs operating under mixed friction conditions.
