“…Due to the fact that in the hip joints there are mechanisms of wear due to sliding due to the movements of the Patient and/or erosive wear due to the decalcification of the bones, the tribological methods Block on Ring (Block-on-Ring) governed by the standard ASTM 137-97 [11] [15], [16] and Erosion by Solid Particles (Solid Particle Impingement) of the standard ASTM 76-02 [10], [15] to analyze the effects of decalcification in these bone tissues. In the research process; It began with the calculation of the tribological variables from the mass data of the bone densitometry analysis, using equation 1.…”

In the Dominican Republic osteoporumsis is affecting many people. This disease attacks the structure of bone tissue causing a skeletal disorder characterized by loss of mass, wear and brittle fracture. In this study, the coxofemoral joints of women were analyzed because there is a relative movement between its elements, forming tribological systems that work with precision and efficiency; but, the efforts, friction and wear in this area affect its mobility and resistance. For this reason, through tribological methods, the wear resistance of the joints of 41 women was evaluated. As results, the wear rate and resistance to erosion and adhesion of hip joints were obtained. Observing that the rate of adhesive wear in the Patients is higher than the erosive rate and as these rates increase over time they reflect the conditions of osteopenia and osteoporumsis as a consequence. Therefore, the resistance of the tissues decreases.

“…Wear is a progressive loss of material from the surfaces during chemical www.advsustainsys.com and/or mechanical processes. [282] The worn-out surfaces of kenaf fiber reinforced epoxy (KFRE) composite have been observed at different operating parameters. It is found that high thermomechanical activity is responsible for the debonding and formation of micro-cracks thereby deteriorating the fiber-matrix interfacial bond and increasing the wear on the application of high load.…”

Sustainable fiber reinforced polymer (FRP) composites from renewable and biodegradable fibrous materials and polymer matrices are of great interest, as they can potentially reduce environmental impacts. However, the overall properties of such composites are still far from the high-performance conventional glass or carbon FRP composites. Therefore, a balance between composite performance and biodegradability is required with approaches to what one might call an eco-friendly composite. This review provides an overview of sustainable FRP composites, their manufacturing techniques, and sustainability in general at materials, manufacturing, and end-of-life levels. Sustainable plant-based natural fibers and polymer matrices are also summarized, followed by an overview of their modification techniques to obtain high-performance, multifunctional, and sustainable FRP composites. Current state-of-the-art mechanical and functional properties of such composites are then surveyed, and an overview of their potential applications in various industries, including automobile, aerospace, construction, medical, sports, and electronics is provided. Finally, future market trends, current challenges, and the future perspective on sustainable natural FRP composites are discussed.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adsu.202200258.

“…Truhan et al [73] reported the details of the experiment. The wear volume can be defined by measuring the sample between each wear test when the material loss was greater than 3 mg, according to the principles of wear measurements [74]. The wear rate of the ring and liner of the experimental material was calculated by the following equation:…”

This study investigates the thermophysical and tribological characteristics of engine oil (SAE 10W-40) using multiwalled carbon nanotubes (MWCNTs) as nanolubricant additives. The MWCNT additives based nanolubricant were formulated using an ultrasonic probe. The tribological performances of MWCNTs nanolubricant were evaluated by a reciprocating platform that simulated the piston ring and cylinder liner interface under various circumstances (i.e., contact loads and sliding velocity). The thermophysical performances of MWCNTs nanolubricant were evaluated using ultraviolet-visible spectrometry, Brookfield viscometers, a thermal conductivity meter, and thermogravimetric analysis. Furthermore, the wear mechanisms of the frictional surfaces were supported by field emission scanning electron microscopy and energy dispersive spectrometer. Critically, the flow characteristics of MWCNTs nanolubricant samples displayed non-Newtonian (shear-thinning) behavior, but the behavior of SAE 10W-40 oil was similar to Newtonian fluids. The friction coefficient decreased by 4%-34% and 26%-32% at different loads and speeds. Moreover, the specific wear rate of the ring and liner surfaces decreased by 29% and 40%, respectively, at 240 N load and 0.33 m s −1 velocity after a sliding distance of 22.57 km. These results suggest that MWCNT additives based nanolubricant effectively lubricated the mechanical applications.
