Research results have demonstrated that the accumulation and blocking of wear debris are the main reasons for thread seizure. This study proposed a theoretical model to predict the wear volume on thread surface in the tightening process for the first time. First, many sub-regions on the thread surface were divided. The real contact force and area on each region were calculated considering the nonuniform axial load distribution in a bolted joint. Second, for each sub-region, the micro morphology was characterized by fractal function. Based on the fractal contact theory, the contact model of single asperity was built, and the contact force and area of single asperity were calculated in the stages of elastic, elastoplastic, and plastic deformations. Subsequently, the contact force and contact area of each sub-region were obtained by integral on single asperity. The former was compared with the contact force of sub-region calculated by nonuniform axial load distribution to determine the termination condition of iteration. The latter was brought into the wear prediction model based on Archard wear theory. According to the theoretical model of predicting the wear volume on thread surface, the effects of axial load distribution coefficient, preload, fractal parameters, friction coefficient, and thread pitch on the wear volume of thread surface were analyzed and discussed. Finally, experiments were conducted to validate the reliability of the proposed theoretical prediction model for wear volume.</p></div>","PeriodicalId":806,"journal":{"name":"Tribology Letters","volume":"73 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organic borate esters, as lubricating additives, have core competitiveness over traditional lubricating additives containing S, P, and Cl. Borate esters not only overcome the poor corrosion resistance of traditional additives, but also have excellent load-bearing capacity and extreme pressure performance. In addition, introducing fatty acid diethanolamide containing active groups such as hydroxyl and amide bonds into borate esters enhances the adsorption capacity. In this article, three borate esters with different carbon chain length were prepared, namely stearic acid diethanolamide borate ester with a chain length of 18, tetradecanoic acid diethanolamide borate ester with a chain length of 14, and octanoic acid diethanolamide borate ester with a chain length of 8. The as-prepared borate ester, especially C<sub>18</sub>ONB, exhibits excellent tribological properties as lubricant additives in poly (a-olefin) (PAO6), significantly improving the friction reducing and antiwear properties of the base oil. This is due to the weak polarity of C<sub>18</sub>ONB with long carbon chains, which exhibits good solubility in PAO6 with weaker polarity and forms thick multilayer viscoelastic adsorption film on the friction surface. In addition, the adsorption film undergoes tribochemical reactions during the rubbing process, generating a tribofilm containing excellent lubricants such as B<sub>2</sub>O<sub>3</sub> and BN, which further plays a good role in reducing friction and antiwear.</p></div>","PeriodicalId":806,"journal":{"name":"Tribology Letters","volume":"73 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notwithstanding the aforementioned advancements, challenges pertaining to implant fixation and tribological surfaces persist. The advent of progressive technologies, such as three-dimensional printing, offers a promising avenue for addressing these challenges in implant design and surface engineering. The Ti6Al4V and CoCrMo alloys, renowned for their biocompatibility and osseointegration properties, represent promising printable materials, although they are susceptible to wear on articulating surfaces. In order to mitigate the effects of abrasion, it is essential to implement surface treatments to facilitate the formation of a robust lubricating film.

The study employs a reciprocating simulator and colorimetric interferometry to observe the contact area and measure the coefficient of friction (CoF) of modified surfaces. The findings demonstrate that textured surfaces and the combination of electrochemical polishing result in an increase in the thickness of the protein lubrication film, which may potentially reduce wear.

However, the friction mechanism considering electrostatic interaction and adhesion of elastoplastic materials on the contact interfaces remains poorly understood. A sliding friction model considering the van der Waals attraction, repulsive and electrostatic interactions is established in this work. The effect of charge density on the normal force, friction force, contact area and stress distribution is thoroughly investigated. And the repeated sliding friction process is also quantitatively analyzed. It is shown that adhesion enhances with the increase of surface charge density. Moreover, the contribution of electrostatic interaction to adhesion in the contact process is always greater than that to friction in the sliding friction process under the conditions studied. In the initial stage of friction, the friction will gradually increase and the normal force will gradually decrease. It is also found that a higher charge density results in a lower normal force in the friction process. Furthermore, the increase of charge density leads to a bigger contact diameter and the increased asymmetry of stress field, resulting in the increase of friction force, equivalent plastic strain and friction coefficient. In addition, both normal force and friction force arrive at a steady state after several repeated friction circles for elastoplastic materials, which is due to the fact that the contact diameter tends to be constant because of the accumulation of plastic deformation. This work reveals the contribution of electrostatic interaction to friction during adhesive sliding process and provides some insights into the adhesive friction problem considering electrostatic interaction.</p></div>","PeriodicalId":806,"journal":{"name":"Tribology Letters","volume":"73 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142826178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper focuses on the tribological properties of glass fiber reinforced PA66 composites in self-mated contact using a pin-on-disc tribometer. The effects of glass fiber content, PV (the product of the contact pressure and sliding speed), and lubrication on the tribological properties of the specimens are also investigated. The results show that the glass fiber reinforced PA66 exhibit higher coefficients of friction and specific wear rates than PA66 under dry sliding conditions. This is probably due to the peeled glass fibers during the sliding process acting as abrasive particles which have an aggressive effect on the surface. Under grease lubricated conditions, PA66 + 33% GF has the lowest coefficient of friction and specific wear rate due to its higher strength. Under dry sliding conditions, all specimens show the highest friction coefficient and specific wear rate at 30 MPa·m/s with the change of PV value. Under grease lubricated conditions, all specimens show the highest friction coefficient and specific wear rate at 4 MPa·m/s with the change of PV value. The addition of grease improves friction and wear of PA66 composites under most of the experimental conditions. However, the specific wear rates of PA66 and PA66 + 13% GF under grease lubrication are higher than those under dry sliding conditions at low PV values.

The results show that the humidity can effectively slow down the wear of graphene in the sliding electrical contact interface by two key mechanisms. Firstly, as revealed by the infrared temperature measurements, higher humidity can significantly reduce the Joule heating. Secondly, X-ray photoelectron spectroscopy shows that with the existence of the electric current, at high humidity water molecules can passivate the graphene carbon dangling bonds more readily thereby reducing oxidation and slowing down the wear process.
