Abstract
The constant development of environmental protection causes the necessity to increase the efficiency of machines. By increasing the efficiency of machines, energy losses can be limited, leading to lower energy consumption. Friction reduction leads to an increase in efficiency and a decrease in wear. In this paper, selected surface texturing methods, such as burnishing and abrasive jet machining, with their limitations are presented. Thanks to those processes, various surface textures can be obtained. Examples of applications of these methods for friction and wear reduction are shown.

Scheme of surface texturing by abrasive jet machining method
When the sliding distance was larger, the wear intensity considerably increased. This increase was probably caused by oil pocket filling, which was caused by the smallest oil capacity
Summary
Surface heating by the laser beam can lead to the creation of a heat-affected zone In some cases, this disadvantage is unacceptable, especially for coated sliding elements. After laser texturing, burrs occur around oil pockets and additional operation is required to remove them Other techniques, such as burnishing (embossing) [11], mechanical polishing, milling [12], etching [13], abrasive jet machining [14] or a combination of these methods [15], can be used for dimple creation. In the surface layer after burnishing and abrasive jet machining, compressive residual stresses are created. They have positive effects on wear resistance and fatigue strength.
