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}

This study employs AFM to investigate the microscopic removal mechanism of Co CMP in an air environment, using Si, SiO<sub>2</sub>, and diamond probes as abrasives. The microstructure and chemical state of the scribed Co surface were analyzed using Hertz contact theory, AFM, SEM, XPS, EDS, and HRTEM. The results demonstrate that the probe material and applied load significantly affect the wear depth and width. The depth obtained by SiO<sub>2</sub>, Si, and diamond probes is about 1, 7, and 70 nm, respectively, under the same load. The Si and diamond probes primarily remove material through mechanical plowing, whereas the SiO<sub>2</sub> probe combines mechanical plowing with chemical reactions. XPS analyses revealed that the SiO<sub>2</sub> probe facilitated the formation of more Co<sub>3</sub>O<sub>4</sub> on the Co surface. HRTEM results showed a Co oxide film (∼1.5 nm thickness) and an amorphous Co layer (∼15 nm thickness) in the scribed region. The oxide film enhanced adhesion, forming a protective layer that hindered further material removal and reduced friction. This study provides theoretical support for optimizing Co CMP processes, which is crucial to next-generation integrated circuits.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"205 ","pages":"Article 110553"},"PeriodicalIF":6.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093535","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}

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}
