“…Combined effect of loads and sliding speeds affect the amount of friction force. Wear rate was found to decrease with increase in hardness (de Wit et al, 1998;Holmberg and Mathews, 1994;Al-Samarai et al, 2012;Paul and Sellamuthu, 2016). The effect of engine oil as a lubricant on the wear coefficient has been reported in this section.…”

This paper investigates the effect of SAE grade 20W50 engine oil as a lubricant on the wear behaviour of chromium nitride (CrN) coating deposited by PVD process at higher loads and speeds by pin on disc tribometer. The specific wear rate ranges from 9.82 × 10-5 to 2.87 × 10-5 mm 3 /Nm in dry condition whereas in lubricated condition 0.97 × 10-5 to 0.19 × 10-5 mm 3 /Nm. Successive increase of speed and load rises the temperature of wear track from 65°C to 178°C in dry condition while 34°C to 40°C in lubricated conditions results to decrease in friction coefficient, which has immense influence on the wear resistance of coating. The wear mechanism of the coatings was analysed by SEM and EDS and found deformation, cracks and, nitride particle pull-out, built up edge formation, erosion and adhesive wear coupled with oxidation wear. The highlights of the paper are: 1) tribology of CrN coating against cylinder liner material as counter face summarised; 2) research has practical Effect of lubrication on the wear behaviour of CrN coating 61 applications for piston ring with the influence of engine oil; 3) temperature ranges from 65°C to 178°C in dry and 34°C to 39°C in lubrication during wear test; 4) the wear mechanism is combination of three body abrasion, metal transfer and oxidation.

“…Laser cladding is a popular method for improving the wear resistance of aluminum alloy drill pipes due to its advantages of fast solidification, low substrate deformation, good metallurgical bonding, excellent performance, and good forming quality [12][13][14][15]. Ni-based powders have been studied and widely used in laser cladding materials for their good wettability, corrosion resistance, high-temperature self-lubrication, and moderate price [16]. However, applying laser cladding on the entire substrate surface may result in defects such as porosity, cracks, and material waste [17,18].…”

To enhance the lifespan of drill pipes and minimize wear, this study introduces a bionic structure model inspired by the pit shape structure found in the dung beetle’s abdomen. The stress distribution and wear of bionic pitted structure and ordinary structure are simulated by finite element software. The findings revealed that the bionic structure significantly improves stress distribution, resulting in an impressive 81.3% increase in lifespan. Subsequently, the surface of the 7075 aluminum drill pipe was coated with Ni powder by a laser cladding system. Wear tests were conducted to analyze the wear and surface damage behavior of the cladding layer. The microstructure, composition, and microhardness of the cladding layer were measured and observed. The results showed that the cladding layer was mainly composed of Al3Ni2 and had high hardness. Additionally, a transition region exists between the cladding layer and the substrate, comprising relatively low hardness Al, thereby enhancing the drill pipe’s ability to withstand alternating loads. Furthermore, the bionic structure possesses the capability to store particles, effectively reducing the occurrence of abrasive wear and increasing the lifespan by 70.0%.

“…Many manufacturing techniques like powder metallurgy, deposition techniques, casting and spraying were preferred to fabricate FGM. Paul [11] suggests centrifugal casting as the most preferred and reliable over other fabrication techniques due to its low cast irregularities, good physical strength and advantageous metallurgical structure. Cu-5wt.%WC with indium doping was subjected to non-lubricated slide tribology investigation by Hong et al [12], which revealed 38% improvement in anti-wear when tested on a tribo-tester under normal load (of 10 N).…”

Dry sliding performance of Cu-11Ni-4Si/10wt.%Al2O3 graded composite was investigated statistically and experimentally using pin-on-disc wear tester. Microstructural analysis revealed maximum gradient concentration of ceramics towards the inner radial wall of developed composite. The wear analysis was based on Taguchi’s L27 orthogonal array and Regression models, at tribo-parameters (load-15, 25, 35 N, slide velocity-1.5, 2.5, 3.5 m/s and slide distance-750, 1500, 1250 m). Wear raised with proportional rise in load and distance. Trend analysis of influential factors against wear response was studied using Analysis of Variance. The influence of process conditions and their interactions on the wear are also detailed. Worn surface analysis identified the formation of Mechanically Mixed Layers at intermediate velocity. This had a major influence over the improvement of wear resistance. This developed composite is suggestable for diverse automobile components of various tribology applications.
