| Abstract | An analysis of the geometric features and functional purposes of different classes of regular microreliefs has been conducted. Some optimal geometric parameters for the grooves of regular microreliefs (cross-sectional and longitudinal shapes and sizes) have been determined to ensure optimal surface performance in friction pairs and facilitate relative reciprocating motion. A new classification of regular microrelief, called the volumetric class microrelief, has been presented. The groove of this microrelief and its constituent elements have been considered a basis for forming multiple microrelief options with different geometric parameters, constituent elements, and their mutual arrangement within the groove and within the microrelief. This approach will enable the creation of volumetric microreliefs, both regular and partially regular, with different functional purposes. Depending on the geometric features, these types of relief can be applied to surface elements subject to non-uniform wear at the locations of most significant dynamic loads (connecting rod liners, cylinder liner surfaces of internal combustion engines, etc.). The optimal shape of the cross-section of the microrelief grooves of the volumetric class is established under the condition of the maximum value of the residual groove area when the surface is worn by 50% of the groove depth. For a rectangular cross-sectional profile, the residual groove area relative to the initial one is 81%; for a triangular one, 50%; and for a semicircular one, 69%. The groove shape of the micro-relief has been justified using an analytical method. The main features of the classification of volumetric class microreliefs have been identified, dividing them into two groups: the first one, describing the specific geometry of the microrelief grooves, and the second one, describing the particular features of the mutual arrangement of these grooves, creating a unique pattern of microrelief on the surface. |
