“…Therefore, 99.9% of the groove surface transferred to the pile-up, which means that 0.07% corresponded to a loss of material. In accordance with Rajendhran et al [ 57 ], this could be due to the micro-ploughing mechanism, which represents the steady-state formation of a groove that has ridges on both sides formed by local plastic deformation without the formation of wear debris because the percentage of material loss is almost negligible. The area of the groove surface of Ti-6Al-4V was close to 71.8%, and the pile-up area 27.9%.…”

The increase in longevity worldwide has intensified the use of different types of prostheses for the human body, such as those used in dental work as well as in hip and knee replacements. Currently, Ti-6Al-4V is widely used as a joint implant due to its good mechanical properties and durability. However, studies have revealed that this alloy can release metal ions or particles harmful to human health. The mechanisms are not well understood yet and may involve wear and/or corrosion. Therefore, in this work, commercial pure titanium and a Ti-6Al-4V alloy were investigated before and after being exposed to a simulated biological fluid through tribological tests, surface analysis, and ionic dissolution characterization by ICP-AES. Before exposure, X-ray diffraction and optical microscopy revealed equiaxed α-Ti in both materials and β-Ti in Ti-6Al-4V. Scratch tests exhibited a lower coefficient of friction for Ti-6Al-4V alloy than commercially pure titanium. After exposure, X-ray photoelectron spectroscopy and surface-enhanced Raman spectroscopy results showed an oxide film formed by TiO2, both in commercially pure titanium and in Ti-6Al-4V, and by TiO and Al2O3 associated with the presence of the alloys. Furthermore, inductively coupled plasma atomic emission spectroscopy revealed that aluminum was the main ion released for Ti-6Al-4V, giving negligible values for the other metal ions.

“…After each test, the surface was thoroughly cleaned in acetone by ultrasonic cleaning (b-sonic, NLPURE, NL) for 10 mins. The procedure for testing the mechanical properties has been explained in detail [41]. The mass measurements of the samples were performed using an electronic balance (AX223E, Ohaus Corporation, USA) with an accuracy of ± 0.1 mg.…”

“…Therefore, employing a test able to provide strength of interparticle bonds in the shallow surface would be more desirable in crust abrasion studies. The scratch test is a tribological technique that simulates the wear process and provides abrasion characteristics of the materials under controlled conditions (Rajendhran et al, 2021; Vencl et al, 2010). In the scratch test, a pin scratches the intended surface, and the normal and tangential forces applied on the pin are measured continuously during scratching.…”

Crusts play a crucial role in the reduction or control of wind erosion. In this regard, the resilience and durability of crusts are of prime importance. Crusts have high resilience and durability against wind flow shear stresses; however, they are prone to abrasion induced by saltating particles. Therefore, estimating crust durability in abrasion rupture has practical importance. In this study, a cyanocrust and a biocemented sand crust were subjected to a controlled flux of saltating particles for different sandblasting periods to provide a framework for predicting crust rupture. The velocity and pre-and post-collision energy of the saltating particles were measured using high-speed photography. The changes in the strength of the crusts after different periods of sandblasting were determined using a scratch test. The results suggested that the average strength of the cyanocrust and biocemented sand crust became 0.25 and 0.7 of their corresponding initial values after 30 min of sandblasting. Also, the average stiffness of the cyanocrust and biocemented sand crust decreased to 0.5 and 0.9 of their initial values, respectively. Furthermore, the amount of impact energy absorbed by the crusts increased by the deterioration of the crusts. Compiling the results of the wind tunnel experiment and scratch tests yielded an exponential equation which can be used to estimate crust durability in a given condition of saltation. Based on this equation, the cyanocrust and biocemented sand crust will break down entirely after 23 and 449 min, respectively, at a wind velocity of 6.8 m/s and a saltation flux of 1 g/s/m.
