“…SEM images at different magnifications of the P110 worn casing surface after conducting the wear test under the above conditions are shown in Figure 7 . It can be observed that the dominant wear mechanism was abrasive wear, as evidenced by the longitudinal grooves on the worn surface [ 31 ] and the plastic flow under the effect of load and shear stress [ 21 ].…”

To understand and quantify casing wear during drilling operations, an experimental setup with real drill pipe joints (DPJ) and casings was designed and used to carry out wear tests, simulating various operating conditions and environments. P110 steel casing samples were tested under dry and wet conditions. Actual field oil- and water-based fluids were utilized to lubricate the contact area at two different side loads (1000 N and 1400 N) and DPJ speeds (115 and 207 rpm). The results show that for the same testing conditions, the casing wear volume and wear factor under water-based lubrication were more than twice those obtained under oil-based fluid testing. As expected, the wear volume and wear factor were highest under dry conditions. Moreover, it was noticed that, as the normal load was increased at a constant rotational speed (rpm), the wear factor increased. On the other hand, raising the rotational speed at the same applied load reduced the casing wear factor, due to the observed absence of adhesive wear and possible localized softening effects at higher speeds. SEM analyses of the worn areas showed that under dry conditions, the main wear mechanisms were abrasion and delamination. However, both adhesive wear and abrasive wear mechanisms were observed under oil-based lubrication. The energy dispersive spectroscopy (EDS) analysis of the worn surface revealed that at higher loads and speeds, a heavy transfer of particles from the oil-based lubricant took place. On the other hand, some contaminants of the water-based lubricant were observed on the worn surfaces.

“…Even when ploughing has changed the surface, very little of the substance that has been transported ultimately splits from the surface. Deep, lengthy fissures shown on the specimen remain unchanged due to surface stress from repeated ploughing (29) . It is based on the behaviour of surfacelevel dislocations, the creation of subsurface cracks and voids, and the subsequent merging of fractures by surface shear deformation.…”

Objectives: To evaluate the tribological and corrosive characteristics of an additively printed gyroid Ti-6Al-4V for Bio medical implant application. Methods: Direct Metal Laser Sintering with regulated input process parameters were used to print the samples. Corrosion investigations have been completely investigated using Potentiodynamic polarization under simulated body fluid conditions. The wear parameters for the samples were maintained with normal load ranging from 10 to 50 N, with sliding velocity ranging from 0.5 to 1.5 m/s for a sliding distance of 1000 m. The further study investigates the impact of load and velocity on the coefficient of friction (COF) and wear rate of the Gyroid samples. Findings: According to the results obtained, the material with the highest resistance to corrosion is exhibited by gyroid lattice Ti-6Al-4V that has a porosity of 60%. These samples exhibited by a worn-out rate of 2 x 10-11 m 3 /m and 5.3 x 10-11 m 3 /m for the normal load of 10 N and 50 N respectively. Minimum wear rate of 3.3 x 10-11 m 3 /m was obtained for a sliding velocity of 0.5 m/s, where a maximum wear rate was obtained at 1.5 m/s of 3.7 x 10-11 m 3 /m. Sample C has better tribological properties and is shown good wear resistance, when compared to sample A & B, which is attributed to the highest micro hardness of sample C of 467 HV. Novelty: The work presented in this study exhibits a unique approach by fabricating a gyroid lattice structure with varying levels of porosity. The limited availability of literature on tribological and corrosion issues necessitates the identification of a unique research need. An investigation of the effect of wear mechanisms on the tribological features of Gyroid Ti-6Al-4V is considered to be a unique research attempt.

“…Understanding the wear mechanisms in the process of friction makes it possible to determine the conditions for changing wear modes and the range of acceptable triboloading conditions. Knowledge of both the wear pattern and wear mechanisms of the material is also necessary to understand the mechanisms of material failure and chemical effects upon contact [21].…”

Wear modes in testing the antifriction layer of babbitt B83

et al. 2022

View full text Add to dashboard Cite

In this work, study of wear modes of antifriction layers of B83 babbitt during tribological tests was carried out. The assumed conditions for changing wear modes were determined during testing with a continuous increase in load by analyzing data of changes in the coefficient of friction and temperature near the contact zone. The data obtained made it possible to conduct experiments for a deeper study of the processes occurring in the friction zone. The results of friction experiments and studies by electron microscopy confirmed the correctness of the assumption about the conditions for change of wear modes. Changes in wear modes and wear mechanisms were judged by the behavior of the friction coefficient, the difference in friction surfaces, wear products, and wear intensity. The results obtained will make it possible to determine and recommend the modes of "wear-free" operation of the babbitt alloy.
