“…Wang et al [228] used comparative molecular field analysis and comparative molecular similarity indices analysis methods to analyze the antiwear properties of a series of 57 esters, and they proposed a predictive 3D-quantitative structure tribo-ability relationship model, which considers much more governing parameters than previous models. Finite element simulation was used to predict the failure process of self-lubricating spherical plain bearings in the swinging wear condition based on the Archard adhesive wear equation [229]. Both the running-in and stable wear stages were investigated.…”

The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.

“…Two phases during the wear process can be highlighted as observed by [14]: the initial wear stage with a sharp increase of the wear depth per turn; then the stable wear stage where the wear depth per turn is linear. Thus, from this second wear stage, the wear depth can be anticipated.…”

Wear Behavior of a Bio-inspired Bearing for off-center Loads

Misalignment is one of the most common causes of wear in bush bearings. Design improvements have been proposed by research studies for years. Unfortunately, it did not efficiently reduce the phenomenon. Classic geometrical designs sometimes reach their limits. For this reason, a bio-inspired design is proposed to solve the impediment. In this article, a bio-inspired bearing suited to misalignment was tested and compared to a classical bush bearing. The contact pressures of both bearings were compared with static finite element simulations for off-center load. Due to the complex shape of the involved contact, the performances of both bearings were also studied over time. Their wear behaviors were predicted with a numerical method. The methodologies emplaced to simulate the wear are described in this paper. Particularly, the wear coefficient determination obtained by experimental testing is detailed. The results for the classical bearing are in accordance with the literature. The pressure value, the contact zone and the wear depth are compared and discussed. Although the pressure is not uniformly distributed over the bio-inspired bearing, the simulations show a deeper wear on the classical bush bearing than on the bio-inspired bearing. Therefore, the superiority of this bearing is proved.

“…However, the wear damage of PTFE/Nomex fabric composites can be easily accelerated by the easy loss of PTFE fibers and weak bonding between the resin matrix and fabric, influencing the service life of the composites [16][17][18][19]. Thus, it is critical to seek promotion on tribological properties for the PTFE/Nomex fabric composite, which is an essential part of the bearing [20][21][22].…”

Graphite/graphene particles were employed as functional fillers to modify hybrid polytetrafluoroethylene/polyisophthaloyl metaphenylene diamine (PTFE/Nomex) fabric-reinforced phenolic composites. The tribology behavior was investigated using a ball-on-disk wear tester, together with a 3D digital microscope. The graphite/graphene exhibits the synergetic effect from the results, which not only reduces the friction efficient but also improves the wear resistance of the composites. Moreover, the wear mechanisms were studied by the wear surface microstructure analysis. It is proposed that the synergetic effect includes mainly the positive rolling effect from the graphene and an improved load-carrying capacity brought by graphite. In addition, in order to obtain the optimized formulation to satisfy the bearing application, the influence of graphite and graphene content on the tribological property of the composites was studied in detail. On the basis of that, the application research was carried out on the bearing oscillating wear test, which will evaluate the engineering service life of the composite.
