“…Many years ago a surface directionality was found to be a way to improve tribological performances of sliding elements [6]. Therefore, structures with parallel or cross-hatched grooves [7][8][9][10] were created. Textured surfaces with isolated dimples are also used [11][12][13][14][15].…”

“…According to Costa and Hutchings [21] and Duarte et al [22] parallel textures guide the lubricant away from the contact leading to a smaller film thickness and, thus, higher coefficient of friction. The authors of papers [10,23,24] found that a decrease in the honing angle led to lower coefficient of friction of cylinder liner-piston ring pack. Probably a small honing angle enhanced hydrodynamic action.…”

“…Abrasive jet machining can be an alternative to laser texturing [28,[37][38][39]. The other methods include electrochemical etching, lithography [12], photochemical texturing, burnishing (embossing) [30,40] and some kinds of machining (honing [8][9][10] or grinding). A sharp tip can be also used for creating grooves [41].…”

Surface texturing is an option of surface engineering resulting in reduction of friction due to the creation of isolated dimples or grooves on sliding surfaces. The purpose of this work is to find the effect of the groove bottom profiles on the reduction of the friction force. Investigations were conducted using an Optimol SRV5 tribotester equipped with a pin-on-disc module. A disc made of 42CrMo4 steel, with a 100 mm diameter acted as a sample. A counter-sample was made of the same material, however, its diameter was 20 mm. The sliding conditions were selected to be similar to those of a sliding crankpin bearing pad operating in a high-performance internal combustion engine. Surface texturing was found to be beneficial for a reduction in the friction coefficient up to 55% in comparison to the untextured disc. Tribological performances of discs with spiral groove patterns were better than those with a radial layout. In most cases the convergent profile of the groove bottom was superior to the dam shape.

The method of the base (valley) one-process profile modeling on the basis of the measured two-process profile was developed. The base one-process random profile of the Gaussian ordinate distribution is characterized by the standard deviation of the profile height and the correlation length. The problem of estimation of the correlation length of this one-process profile exists. In the procedure of the correlation length estimation, information about the averaged shape of the autocorrelation functions of many one-process profiles after the same type of machining is required. The correlation length of the base one-process profile can be obtained on the basis of the vertical truncation of the measured two-process profile. The average error of the correlation length estimation was not higher than 7%, while the maximum error was not larger than 14%. This method can be extended to simulate the one-process texture of 3D (areal) surface topography.One-process surfaces are well described. The analysis of the measured one-process texture is simple. The digital filtration is an easy task. A typical Gaussian filter can be used. A one-process random profile can be easily described by only two parameters: height and horizontal. It can be completely characterized by the standard deviation of height (Pq), and a correlation length (CL), i.e., the distance at which the autocorrelation function slowly decays to a value of 0.1 [11,12]. Figure 1 presents the example of the random one-process profile and its autocorrelation function with the CL parameter.
