In this work, commercial polyalphaolefin oil has been encapsulated within polystyrene shell for microcapsules synthesize, which have been further introduced into a specially designed “soft” and “hard” polysiloxane/Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> nanocomposite coating. The tribological test results show that the prepared composite coating displays a remarkable synergistic lubrication effect, achieving nearly superlow friction of 0.016 and an ultralow wear rate of 1.9 × 10<sup>−8</sup> mm<sup>3</sup>/N·m simultaneously. The comprehensive mechanism analysis indicates that the extraordinary superlubrication effect is derived from the desirable mechanical properties of the polysiloxane/Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> nanocomposite coating and the favorable liquid lubrication effect of embedded oil microcapsules, wherein the former could enhance the conformity of surface morphology when the mating surfaces are in contact, thereby facilitating the formation of numerous microchannels; in the meanwhile, the latter could be friction-induced ruptured and then release oil molecules at the friction interface, adsorbing to the coating surface and forming an effective boundary-lubricating oil film. As a result, a remarkable synergistic lubrication effect could be created to significantly enhance the lubrication effect. It could be anticipated that this finding could expedite a broader utilization of self-lubricating coatings and superlubricity technology in the practical industrial sectors.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"205 ","pages":"Article 110555"},"PeriodicalIF":6.1,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HRTEM results showed a Co oxide film (∼1.5 nm thickness) and an amorphous Co layer (∼15 nm thickness) in the scribed region.

In this study, we developed a synergistic protection system by incorporating CrN coating and ZnAl layered double hydroxides (ZnAl LDH). The CrN coating was deposited using magnetron sputtering, and ZnAl LDH was synthesized via the hydrothermal method. To enhance the dispersion and tribological properties of ZnAl LDH in base oil, surface modification with stearic acid (SA) was performed through dehydration condensation bonding between the -OH groups on the ZnAl LDH surface and the -COOH groups on SA. Tribological tests were carried out to evaluate the lubrication properties of the two different LDHs when used as additives at varying concentrations in PAO-10 oil. The results demonstrate that adding 2.5 wt% SA-ZnAl LDH significantly improved the anti-wear performance of CrN-coated surfaces. This improvement is primarily attributed to the adsorption of LDH onto the CrN coating surface, which promote tribo-film formation. Overall, by benefiting from the synergistic effect between the LDH with superior lubricating properties and the CrN coating's excellent mechanical characteristics, a low-wear synergistic protection system was established, effectively protecting the steel substrate from severe wear.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"207 ","pages":"Article 110540"},"PeriodicalIF":6.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143610228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, insufficient lubricant supply can lead to a critical issue known as starved lubrication, emphasizing the need to address this concern under limited lubricant supply (LLS) condition. In this study, a ball-on-disc lubricating film test rig, with a circular contact, was employed. The impact of zinc dialkyl dithiophosphate (ZDDP) interfacial adsorption on the lubrication characteristics under LLS condition was investigated by introducing ZDDP as an anti-wear additive. A dichromatic interference intensity modulation (DIIM) approach was utilized to reveal the evolution of the lubricant film at various lubricant supply stages under LLS. Three distinct lubricant supply stages were identified: the fully flooded stage, the transition stage from fully flooded to starved lubrication, and the starved lubrication stage. The mechanism of ZDDP interfacial adsorption during different lubricant supply stages was evaluated by analyzing variations in oil reservoir morphology, lubricant film thickness, and friction coefficient. The results indicate that, under LLS conditions, changes in the oil reservoir directly influence the transition between lubricant supply stages. The adsorption effect of ZDDP was found to promote lubricant entrainment and improve the lubricant supply in the inlet area during the second and third lubricant supply stages, thereby enhancing the anti-collapse capacity of the lubricant film. Additionally, in the LLS condition, the improved anti-friction effect of ZDDP is attributed to the synergistic impact of enhanced lubricant entrainment and increased shear resistance.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"205 ","pages":"Article 110552"},"PeriodicalIF":6.1,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
