“…Valleys perpendicular to the sliding direction generate the highest load-carrying capacity. For smooth plateau parts, larger spacing between valleys led to an increase in load-carrying capacity [ 101 ]. Pawlus [ 102 ] revealed that cylinder liner abrasive wear was higher for larger distance between deep valleys.…”

“…A decrease in axial distance between deep valleys from 500 to 200 µm led to a decrease in liner wear of about 30%. Because the honing angle and the spacing between honing grooves are functionally important parameters [ 100 , 101 , 102 ], a comprehensive description of the spatial properties of the cross-hatched structures is needed. Classical spatial parameters do not also describe the pattern of textured surfaces [ 103 ], although a method of their description was developed [ 104 ].…”

Functional Importance of Surface Texture Parameters

Areal 3D analysis of surface texture gives more opportunities than a study of 2D profiles. Surface topography evaluation, considered as 3D dimensional analysis in micro or nanoscales, plays an important role in many fields of science and life. Among many texture parameters, those connected with height are the most often used. However, there are many other parameters and functions that can provide additional important information regarding functional behaviour of surfaces in different applications. The knowledge about the functional importance of various surface properties is low. This review tries to fill this gap. Surface texture parameters are presented in various groups: height, spatial, hybrid, functional, feature, and others. Based on experiences of the present authors and literature review, the relationships among various surface parameters and functional properties are described. A proposal of a selection of parameters on the basis of their functional significations is provided. Considerations for future challenges are addressed.

“…Hybrid TEHL numerical solution problem is determined by the load conditions that have been set, and the solution pressure must meet the earlier mentioned pre-conditions for load balance. The objective optimization problem is a non-linear constrained optimization problem, which belongs to the framework of non-linear programming [36,37]. The load balancing equation is expressed as follows:…”

In the process of gear meshing, it is an inevitable trend to encounter failure cases such as contact friction thermal behavior and interface thermoelastic scuffing wear. As one of the core influencing factors, the gear meshing contact interface micro-texture (CIMT) significantly restricts the gear transmission system (GTS) dynamic characteristics. This subject intends to the contact characteristic model and interface friction dynamics coupling model of meshing gear pair with different CIMT. Considering the influence of gear meshing CIMT on distribution type of hydrodynamic lubricating oil film, contact viscous damping and frictional thermal load, the aforementioned models have involved time-varying meshing stiffness (TVMS) and static transmission error (STE). Based on the proposed models, an example verification of meshed gear pair (MGP) is analyzed to reveal the influence of CIMT on the dynamic characteristics of GTS under a variety of micro-texture configurations and input branch power and rated speed/shaft torque conditions. Numerical simulation results indicate that the influence of CIMT on gear dynamic response (including meshing interface frictional thermal load, malicious damping and impact vibration in the off-line direction of the action) is extremely restricted by the transient contact regularity of the meshing gear surface. Meshing gears dynamic characteristics (especially vibration and noise) can be obviously and effectively adjusted by setting a regular MGP with CIMT instead of random gear surfaces.

Rough surface morphology has a great influence on the service properties of the surface, such as friction [1], wear [2], lubrication [3], contact [4][5][6][7], fatigue resistance [8],…”

Shot peening for semi-finished or finished parts is a high-performance precision manufacturing process, and the final micro-surface morphology has layered superposition features, that is, the original surface features and shot peening features coexist on the part surface. The existing layered superposition theory is based on the idea that the surface is superimposed under different baselines, but it cannot characterize the two-process surface where the characteristic baseline cannot be separated after shot peening. To solve this problem, a new layered surface superposition modeling method is proposed in this paper with the grinding-shot peening surface as the research object. In this method, the main texture features of the grinding surface are extracted by B-spline surface fitting, and the spatial distribution of craters in the shot peening surface is adjusted by this texture feature. The initial profile of the grinding-shot peening surface is constructed according to the Pawlus superposition theory, and its height parameters are adjusted by the time-frequency iteration method. In this paper, the modeling method is verified by the measured grinding-shot peening surfaces with a coverage of 100% and 200%. The results show that this method can not only ensure the uniformity of crater texture on the reconstructed surface, but also ensure that the maximum error of spatial parameters is less than 2%. Moreover, the symmetrical autocorrelation functions of the reconstructed surface are consistent with the characteristics of the measured surface.
