“…This was done to analyze the hereditary influence of processing methods and modes on residual stresses in the surface layer. During the action of concentrated energy flows on the surface, a favorable microrelief (Figure 2), a favorable structure (fine-needle martensite) [19,20], and residual compressive stresses are created. These factors improve after diamond burnishing.…”

“…The combined processing method consists of the sequential use of electromechanical processing (EMP) and diamond smoothing [17,18]. We developed a trial plant consisting of the Start bench lathe, a power source, a quench, a current supply system, and a quenching area cooling system, in which combined processing modes were tested [19,20] (Figure 1). First, the samples were turned on a desktop lathe "Start" (Figure 1): the depth of cut was 1 mm, the part peripheral speed was 26 m/min, the feed rate was 0.3 mm/rev, and the number of revolutions of the machine spindle was 700 rev/min.…”

The purpose of this research was to analyze the change in residual stresses in the surface layer of steel samples taking into account the technological heredity effect on the value and sign of residual stresses. An installation of combined processing was developed. Combined processing consists of sequentially performing electromechanical processing and diamond smoothing. All areas of the samples were studied—after machining (i.e., in the initial state), after electromechanical processing, and after diamond smoothing. The research shows that the sign and value of residual stresses are significantly affected by the combined processing modes. The main parameters of the surface layer are formed at the final stage of the combined processing–diamond smoothing. This paper gives recommendations on the use of combined processing for power plant parts.

“…The equipment for the implementation of laser surfacing is equipped with such laser sources as gas, diode or optical fiber. Diode laser sources are the most suitable for surfacing, since the energy distribution density is the most uniform [15,16]. The used technologies for applying functional composite coatings based on the Inconel 625 (INC625) nickel alloy are not sufficiently perfect, as they are accompanied by possible disadvantages, such as cracks and porosity [17][18][19][20].…”

Single laser tracks of the WC/INC625 composition in a wide range of concentrations of the carbide phase obtained by laser surfacing at various values of the technological parameters of the process are studied. Based on the results of quantitative metallographic analysis, promising compositions of coatings were selected and intervals of technological parameters were established. The modes allowing to obtain objects without cracks, with minimal porosity and a given geometry of the laser track cross-section were determined.

“…There are a large number of wear-resistant products developed in the industry, but with different performances, and it is difficult to ensure both cost and wear resistance (Caltaru et al, 2020;Fedorova et al, 2018;Coronado et al, 2009). Bead weld (BW) technology is widely used to improve the wear resistance of drill pipe joints by virtue of its simple equipment operation and stable welding layer quality and low cost; however, in the surfacing operation, the heat-affected area of the drill pipe joint is large, and the repeated surfacing property varies greatly because of the different wear-resistant products, and it is difficult to guarantee the wear resistance and anti-friction properties (Coronado et al, 2009;Buchely et al, 2005;Truhan et al, 2007).…”

Purpose The purpose of this study is to solve the oil drill pipe joints and casing excessive wear problems and to improve the drill pipe joint-casing wear resistance and anti-friction properties. Design/methodology/approach On the surface of the drill pipe joints using oxyacetylene flame bead weld (BW) wear-resistant welding wire ARNCO-100XTTM prepares welding layer, high-velocity oxygen fuel (HVOF) Cr3C275-NiCr25 prepares coating and subsonic flame spray and remelt (SFSR) Ni60 prepares coating, then comparing and analyzing the friction and wear of the three types of wear-resistant layers and the casing under the condition of 1.8 g/cm3 mud drilling fluid lubrication. The wear resistance and anti-friction performance of the drill pipe joints were evaluated based on the wear situation, finally revealing its friction and wear mechanisms. Findings Three types of wear-resistant layers can improve the surface wear resistance of drill pipe joints, the wear-resistant layer and the substrate are well combined and the welding layers and coating are both dense and uniform. The wear resistance of the HVOF-Cr3C275-NiCr25 coating is 10.9 times that of the BW-ARNCO-100XTTM weld layer, and the wear resistance of the SFSR-Ni60 weld layer is 2.45 times that of the BW-ARNCO-100XTTM weld layer. The anti-friction properties of SFSR-Ni60 welding layer is the best, followed by HVOF-Cr3C275-NiCr25 coating, and the anti-friction properties of BW-ARNCO-100XTTM welding layer is the worst among the three. Originality/value The research results of this paper have great practical value in the process and material of improving the wear resistance and anti-friction performance of the drill pipe joint casing.
