“…The chosen friction coupling (contact on a flat surface) simulates the type of contact specific to non-circular gears with curved teeth. The friction length of 50 mm, considered in the experiments (based on the authors’ experience in the works [ 76 , 77 ]), corresponds to the value at which a stabilization of friction coefficient was obtained (as seen in Figure 4 ) and no influence of the temperature appears (the heat developed by friction phenomenon involves plastic materials change their mechanical characteristics by increasing the temperature). The sliding speed of 0.314 m/s corresponds to the sliding speed obtained on the AMSLER type A135 tribometer at a roller diameter of 30 mm and is close to the speed in non-circular gears from some practical applications.…”

In recent years, there has been a growing interest in the field of 3D printing technology. Among the various technologies available, fused deposition modeling (FDM) has emerged as the most popular and widely used method. However, achieving optimal results with FDM presents a significant challenge due to the selection of appropriate process parameters. Therefore, the objective of this research was to investigate the impact of process parameters on the tribological and frictional behavior of acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) 3D-printed parts. The design of experiments (DOE) technique was used considering the input design parameters (infill percentage and layer thickness) as variables. The friction coefficient values and the wear were determined by experimental testing of the polymers on a universal tribometer employing plane friction coupling. Multi-response optimization methodology and analysis of variance (ANOVA) were used to highlight the dependency between the coefficient of friction, surface roughness parameters, and wear on the process parameters. The optimization analysis revealed that the optimal 3D printing input parameters for achieving the minimum coefficient of friction and linear wear were found to be an infill percentage of 50% and layer thickness of 0.1 mm (for ABS material), and an infill percentage of 50%, layer thickness of 0.15 mm (for PLA material). The suggested optimization methodology (which involves minimizing the coefficient of friction and cumulative linear wear) through the optimized parameter obtained provides the opportunity to select the most favorable design conditions contributing to a more sustainable approach to manufacturing by reducing overall material consumption.

“…Therefore, the drill pipe joints are required to have higher wear resistance. Surfacing a layer of wear-resistant isolation tape on the surface of the drill pipe joint is now the main method to improve the wear resistance of the drill pipe joint; this method is widely used in the oil and gas drilling industry (Haberer et al, 2021;Yuan et al, 2021;Grigoriev et al, 2013;Mobley, 1999;Caltaru et al, 2018;Ripeanu et al, 2018;Ripeanu et al, 2015).…”

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.

The petroleum industry is essential for supplying crude oil, which is vital for fuel and chemicals and drives substantial investments in technologies, especially in regard to increasing the durability of the drill strings used in wellbore construction. This study aims to establish and to validate a hardbanding technology for reconditioning NC50 tool joints subjected to wear, thereby increasing drill pipe durability and reducing the risk of failure during drilling, which can lead to ecological pollution, human safety issues, and financial costs. The hardbanding of the tool joints was carried out using the gas metal arc welding process (GMAW) with two different wear-resistant wires, ARNCO 100XT and FLUXOFIL M58. The equipment designed for this research allowed for the application of high-quality hardbanding layers in very good condition, according to the favorable results obtained by macroscopic analyses, metallographic studies and hardness measurements. The hardbanding procedure of the tool joint drill pipe was documented in a welding procedure specification (WPS), which validates the process and is useful for operators, drilling companies and other oilfield service companies who wish to apply under the same conditions and at the same high-quality level, in a repetitive mode, the reconditioning process to minimize the risk of drill-string failures.
