In this study, a Lignum vitae-inspired composite was fabricated by filament-winding with different winding angles.

After a series of reciprocating-sliding point-contact wear tests under un/water-lubricated conditions, the results showed the filament-winding angle has a significant effect on the tribological performance of the composite. Among these, the winding angle of 55° shows the best capacity of load distribution and advantages in lubrication secretion, resulting in excellent mechanical properties and self-lubricated performance in both lubrication conditions.

The current investigation aims to understand the tribofilm formation mechanism on electrified steel surfaces, helping mitigate the adverse effects of current leakage in electric vehicles (EVs) transmission. A low-SAPS oil was formulated using polyalphaolefin oil (PAO6) and 0.5 wt% zinc isopropyl-isooctyl-dithiophosphate (ZDDP, type T204). Additionally, the commercially fully formulated transmission oil for EVs was used as a reference oil to compare. The current-carrying friction tests were conducted under various DC currents (2–8 A) and temperatures (50–200 °C) at 250 N and 10 Hz using an electrified SRV-IV tribometer. The results demonstrated that the electrical contact resistance (ECR) and coefficient of friction (COF) signals were dynamically compatible, indicating the tribofilm behavior. Notably, the antiwear properties of ZDDP oil were enhanced by up to 58 % compared to the reference oil under various currents at 150 °C. The HRTEM results revealed that ZDDP oil produces a thick antiwear tribofilm up to 654.8 nm, while the reference oil forms a thin tribofilm up to 37.1 nm at 8 A and 150 °C. The electrification effects do not deteriorate antiwear ZDDP tribofilms due to their higher formation rate than the scrape-off rate. Accordingly, these findings will help synthesize new organic oil additives (low-SAPS) and open future opportunities for discovering green alternatives to enhance the durability of EVs transmission.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"564 ","pages":"Article 205746"},"PeriodicalIF":5.3,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097267","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}

To fully interpret the results, mechanical tests of the obtained composites were also performed and a viscosity-temperature analysis of the oils used was performed. In both the case of paraffin and silicone oil, it was observed that adding CSP to the polymer matrix reduces the COF. Paraffin oil tends to reduce the COF by increasing the percentage of filler (regardless of particle size). In contrast, silicone oil has the lowest COF observed in the case of 5 % wt. and the highest granulation. The dominant wear mechanism in the case of paraffin oil lubrication turned out to be micro-abrasion, while in the case of silicone oil, micro-abrasion and micro-adhesion. Moreover, it seems that the lower dynamic viscosity of silicone oil at lower temperatures favored the destructive effect of crushed filler particles on the composite surfaces in the initial parts of the tests.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"564 ","pages":"Article 205745"},"PeriodicalIF":5.3,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096715","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}
