“…The mechanical method is one of the oldest ways to clean machinery and equipment components. The method is based on a direct action on a corroded surface of an element and removal of corrosion products from its surface, which is discussed in detail in References [ 28 , 37 ]. The mechanical method allows for quick cleaning of components, although it requires the use of mechanized tools.…”

“…The mechanical method allows for quick cleaning of components, although it requires the use of mechanized tools. The basic kinds of activities that can be applied during a mechanical cleaning process include hammering, scraping, brushing, needling, grinding, polishing, blast cleaning, and cleaning with loose abrasive, which was characterized in References [ 10 , 13 , 29 , 37 ].…”

This work presents the analysis of functional relationships between fraction size of abrasives and geometric parameters of surfaces after rotary cleaning. The influence of an abrasive type on the effectiveness of rotary cleaning of machine parts with complex geometric features was determined as well. The process of mechanical cleaning, using a rotational method, of clutch springs was performed in the proprietary device for rotational cleaning, which was followed by the computer-aided analysis of the obtained results. The research process was carried out using abrasive materials such as grinding stone, sand, basalt, glass, and fine gravel, and the test samples were clutch springs after eight years of operation. Based on calculated three-dimensional (3D) roughness values of the cleaned samples’ surfaces, qualitative classification of abrasives was determined. The most effective material turned out to be fine gravel, while the worst results were related to basalt usage.

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.

“…There are many methods of oil pocket creation, including honing, 37,41 burnishing, 30,36,42 abrasive jet machining, 27,39,40,43,44 micro-milling 44 and etching. [45][46][47][48] However, laser texturing is the most popular technique of oil pocket creation due to laser precision and relatively short manufacturing time of a single oil pocket. 1 However, this method is not universal due to heat affected zone and pileups created at the edges of dimples.…”

The effect of the apex angle of triangular oil pockets created on a disc surface on friction was studied. Experiments were carried out using an Optimol SRV5 tribotester equipped with a pin-on-disc module under unidirectional lubricated sliding. Both the sample and counter sample was made of steel of 45 Hardness Rockwell C (HRC) hardness. Only 1 ml of oil was put to the inlet side of the contact area at the beginning of each test. All textured surfaces had the same pit-area ratio and an average depth of dimples. Oil pockets were positioned in the spiral array. It was found that the effect of the apex angle of triangular dimples on friction reduction was important. When the normal load was lower, the smallest coefficient of friction was achieved for the sliding pair with a disc apex angle of 60°. Under a larger normal load, a higher apex angle corresponded to a higher coefficient of friction.
