However, its friction performances greatly vary under different loads, and the underlying mechanisms remain unclear. In this study, we developed reciprocating friction tests of TZM alloy in aerobic conditions, and evaluated its tribological properties and mechanism under the normal force ranging from 1 to 10 N. The wear process is primarily affected by oxidation, adhesion, and fatigue wear, and adhesive wear intensifies with increasing load, which mainly results in the gradual decline in coefficient of friction from 1.022 to 0.510, as well as variations of friction performances and wear track morphology, thereby elucidating the wear mechanism. There is a long running-in period at a low load of 1 N, with a significant accumulation of mixed oxides of MoO<sub>3</sub> and Mo<sub>4</sub>O<sub>11</sub> in the wear tracks, leading to a minimal wear rate of 1.68 × 10<sup>–5</sup> mm<sup>3</sup>·N<sup>−1</sup>·m<sup>−1</sup> after 9000 cycles. At 2 N and 4 N, these oxides undergo repeated spalling, crushing, and re-forming processes.

Based on the action mechanism of rare earth on alloys, the influence of material corrugated layered crystal structure, and sulfur content on lubrication properties at the atomic and molecular levels, layered rare earth sulfates have become a new type of high EP performance solid lubricants. Herein, we prepared layered rare earth sulfate materials (RE<sub>2</sub>(OH)<sub>4</sub>SO<sub>4</sub>·nH<sub>2</sub>O, RE = La/Sm/Ce, i.e., RES, LaS, SmS, CeS, respectively) using a mild hydrothermal method for controlled particle size and morphology. To evaluate its applicability, we tested the new solid lubricants against high load, high temperature, long-term, different friction pair materials, and fretting. Overall, the RES samples exhibited excellent lubricating behavior when added to polyurea grease, better than MoS<sub>2</sub>. By adding layered lanthanum sulfate, samarium sulfate, and cerium sulfate, the seizure loads can reach up to 1400, 1300, and 1300 N, respectively. Microscopic analysis of the friction pairs confirmed that the lubricating films formed on the worn surface during friction. Excitingly, the RES materials exhibited excellent synergistic effects on EP performance and corrosion resistance. Thus, these materials have broad application prospects as lubricants.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":806,"journal":{"name":"Tribology Letters","volume":"73 2","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938481","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}

It was shown that higher lubricant viscosity in the high-pressure central zone of the contact leads to lower minimum film thicknesses. This was linked to a reduction in lubricant outflow from the contact through the sides. That is why such effects would not be observed in infinitely long line contacts.

This study develops a contact model for layered materials by extending a previously established viscoelastic half-space contact model. The approach involves converting analytical frequency response functions into influence coefficients, enabling the investigation of the viscoelastic behaviour of ZDDP-derived tribofilms. The results reveal that the tribofilm exhibits a highly fluid-like response when modelled as a half-space body being in contact with a carbon steel ball during indentation or sliding. When bonded to an elastic substrate in its typical thin-film form (on the nanometre scale), the contact behaviour can still exhibit time-dependent characteristics, depending on the operating conditions. Creep and stress relaxation are observed during indentation, particularly under low loads, while high loads result in a more pronounced viscoelastic response in extremely slow-speed contacts. However, under moderate sliding speeds ranging from millimetres to meters per second, time-dependent effects become negligible, regardless of the applied load. These findings indicate that although ZDDP-derived tribofilms exhibit significant viscoelasticity, their behaviour in practical applications generally resembles that of a soft elastic layer, as typical sliding speeds fall outside the range where pronounced time-dependent effects occur.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":806,"journal":{"name":"Tribology Letters","volume":"73 2","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11249-025-01990-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143902753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective was to evaluate the suitability of 3D printed titanium alloy, with and without DLC coating, for THR rubbing surfaces and to investigate the potential benefits of 3D printing technology for friction and lubrication. A pendulum hip joint simulator was employed to replicate the swinging motion of a hip joint, thereby enabling the measurements of coefficient of friction (COF) and the observation of lubricant film formation under realistic conditions between the metal femoral head and acetabular cup. The experiments demonstrated that additive manufacturing enables the creation of specific surface topographies that can enhance protein adsorption, but also introduce surface imperfections negatively affecting tribological properties. The elevated surface roughness of additively manufactured femoral heads did not inevitably result in an increase in COF and was comparable to that of conventionally manufactured femoral heads. The additively manufactured Ti6Al4V head without DLC coating also exhibited a more rapid increase in lubricant film thickness during dynamic motion. In conclusion, the findings indicate that while 3D printing offers promising advancements in implant customization and material properties, its application requires careful consideration of surface finishing and coating methods to achieve optimal tribological performance.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":806,"journal":{"name":"Tribology Letters","volume":"73 2","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11249-025-02002-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143883670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The friction and wear caused by mastication can result in significant damage to both teeth and implants due to the tribological interactions involved. In this study, both extruded and 3D-printed PEEK specimens were fabricated, and their tribological behavior was evaluated against Vita enamel-coated Cobalt–Chromium (Co–Cr) plates under both dry and artificial saliva conditions to simulate the oral environment. The analysis focused on friction coefficients, specific wear rates, and wear mechanisms using linear reciprocating sliding tests. Extruded and 3D-printed PEEK exhibited comparable tribological performance. Under dry conditions, their friction coefficients were 0.306 and 0.318, respectively. In saliva, the coefficients decreased to 0.109 for extruded PEEK and 0.114 for 3D-printed PEEK. Specific wear rates were also closely matched, with extruded and 3D-printed PEEK showing rates of 5.989 × 10<sup>–5</sup> and 6.151 × 10<sup>–5</sup> mm<sup>3</sup>/Nm under dry conditions, and 1.745 × 10<sup>–5</sup> and 1.878 × 10<sup>–5</sup> mm<sup>3</sup>/Nm under saliva conditions. Notably, the specific wear rates of PEEK under saliva conditions were comparable to those of natural human tooth enamel when tested against the enamel-coated Co–Cr plates. This suggests that PEEK, with its proven tribological properties, is suitable for use in dental crown implant applications. These findings highlight PEEK’s potential as a strong and suitable alternative material than conventional for dental implants, demonstrating consistent performance in conditions that closely mimic the oral environment.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":806,"journal":{"name":"Tribology Letters","volume":"73 2","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879607","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}
