Simulation of the Deformational Cutting and the Geometric Parameters of Pin Structures to Analyze the Thermohydraulic Characteristics of Heat-Removal Plates

Improving the Durability of Machine Parts Using a Combined Method

“…Hence, this method can be recommended to improve performance properties of machine parts. The analysis of studies [9][10][11] shows, that formation of regular surface microreliefs for separating friction surfaces with an oil film can increase operational life of a machine part.…”

“…One of the areas of work while dealing with this task is producing machine parts with a regular microrelief. Regular microrelief makes optimization of microgeometry of working surfaces easier and improves its performance properties [9][10][11][12][13].…”

Calculation and Experimental Study of Heat Exchange in a System of Plane-Parallel Channels with Surface Intensifiers

“…Systematic research carried out over many years into the intensification of heat exchange on structured surfaces with ordered vortex generators has led to breakthrough solutions of the thermophysical problem, which combine a high thermal efficiency and a moderate growth of hydraulic losses, and to the creation of heat-exchange devices for industrial purposes [21][22][23][24]. Heatexchange surfaces with annular protuberances and cylindrical grooves, oval trench-like dimples, hemispherical protuberances and depressions [25][26][27][28], spiral and pin fins [29] have been investigated.…”

Controlling the Properties of the Surface Layers of Parts by Forming Regular Micro-Reliefs

“…It essentially lies in the sequential implementation of electromechanical processing and diamond smoothing [7,15,16]. Using this technology, it is possible to technologically control the geometric characteristics of the working surfaces of cylindrical parts [9][10][11][12][13][14].…”

“…The use of some surface plastic deformation methods, i.e. vibration smoothing, diamond smoothing, provides a regular micro-relief on the part surface, reduces roughness, and increases the bearing and supporting capacity of the surface layer [1,2,5,[9][10][11][12][13][14]. For example, the vibrationally smoothed surfaces successfully combine the properties of rough and smooth surfaces: reliable preservation of lubricants in the grooves of the microrelief and increased bonding resistance and low loading of microirregularities, fast conformability in operation and high wear resistance of the surface [10][11][12]15].…”
