“…These alloys are highly resistant to abrasive wear. Results of studies investigating the wear resistance of coatings made of these alloys modified by various additives in different configurations and chemical compositions are reported in numerous papers, among others in [ 8 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ]. According to the literature data, copper was added in order to create conditions for self-organization during the friction process.…”

This paper investigates the friction process between an Fe-based coating and C45 steel with surface-active lubrication, as well as examines the coating surface before and after tribological testing. As a result, it is possible to determine whether the surface undergoes self-organization during friction. Coatings were produced by hardfacing a subeutectic alloy Fe-Mn-C-B modified by silicon, nickel, chromium and copper. Tribological tests were performed using a pin-on-disc tribometer. The pin (coating) and the disc made of steel C45 were subjected to heat treatment (hardening and tempering). The tests were carried out under loads of 3 MPa, 7 MPa and 10 MPa at a constant sliding velocity of 0.4 m/s and a sliding distance of 5700 m using a surface-active lubricant (glycerine oil). Obtained results were compared with the published results of previous tests carried out under the same conditions but under a load of 20 MPa. Obtained microscopic and spectroscopic results demonstrate that that the friction pair materials (the coating made of subeutectic alloy Fe-Mn-C-B modified by Si, Ni, Cr, Cu and C45 steel) and the surface-active lubricant cause self-organization during friction. The friction surface of the coatings has a flay-laminar structure and is covered with triboreaction products. The surface shows the presence of wear-resistant compounds such as oxides, carbides, borides and nitrides.

“…Analyses concerning corrosion phenomenon cover a wide range of research processes in the field of materials science, which are carried out to determine the type of corrosion damage and the causes of corrosion. In the literature [ 2 , 4 , 17 , 35 ], corrosion tests are classified according to various criteria, among them according to the type of conditions in which the tests are performed (i.e., tests in conditions of natural environment and in laboratory conditions). Tests in natural conditions are carried out in corrosive environments such as air, soil, or liquids.…”

“…Very good physical and chemical properties of steel are the reason for its use in many branches of industry. One of the most significant problems in construction and exploitation of machines is the corrosive destruction of iron alloys [ 1 , 2 , 3 , 4 , 5 ]. The effects of this process are losses—direct ones, related to the costs of damaged materials and construction protection, as well as indirect ones, related to the operation of machines.…”

Analysis of the Abrasive-Type Influence on the Effectiveness of Rotary Cleaning of Machine Parts with Complex Geometric Features

2020

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 tests were conducted according to ASTM G133 standard. A ball-on-disc friction combination was used as in [22,23]. As co-specimen in the friction-junction the pure thin silver layer and cooper layer as well as the Al2O3 ball were used.…”

Computer measurement of the friction of thin metal structure created in PVD technology on the flexible substrate

et al. 2019

The paper presents the results of research study on the phenomenon of friction of thin film electroconductive structure created on composite flexible substrate and results of measurement of the friction coefficient. Tribological tests were performed on T-01M tribotester. The measurement tests were conducted according to ASTM G133 standard with a minimum force of 1N. A ball-on-disc friction combination was used. The study was conducted at a fixed temperature of 28 ° C. Due to the nature of the tested samples, non-standard test parameters were used: test time 100 s, data acquisition frequency 10 Hz, slip velocity of the friction node 0.3 m/s on a radius of 11 mm. Based on the obtained results, the friction coefficient of the thin metallic layer Ag and Cu was determined. The obtained mean friction coefficient for a silver layer was 0.59, while for a thin copper layer 0.67. The knowledge of the determined coefficients will allow for effective and optimal use of the textronics materials tested in practical applications. The research methodology does not support determining the usage of the ball-on-disc pair.
