ZnO-IL exhibited good solubility and thermal stability in DIOS. Lubricants containing ZnO-IL showed excellent anti-wear performance under various loads and temperatures. Its deposition on metal surfaces and the synergistic action of benzotriazole groups in the anions effectively prevented corrosion on the surfaces of metal friction pairs, thereby addressing the challenge of friction pair corrosion caused by the hydrolysis of ester-based oils. The ZnO-IL nanomaterial rapidly formed an organic-inorganic multilayer adsorption film on metal surfaces through electrostatic interactions.

This study investigates the effect of the Cr:C ratio on the mechanical properties, microstructure, phase diagram, and both low-stress and high-stress abrasion performance of HCCIs. Alloys with a very high Cr:C ratio exhibited better impact toughness but poorer hardness. Scanning electron microscopy (SEM) and phase diagram calculations elucidated the influence of the Cr:C ratio on microstructure, carbide volume fraction, and carbide type. Abrasion resistance was evaluated using impact abrasive wear (high-stress) and rubber-wheel (low-stress) abrasion on quartzite in open three-body wear. Comprehensive assessments under impact abrasive wear and rubber-wheel abrasive wear conditions suggest that the alloy achieves optimal abrasion resistance with a Cr:C ratio ranging from 8 to 11. Post-wear analysis reveals that surface damage varies between high-stress and low-stress conditions. The microstructure of squeeze HCCIs is significantly influenced by the Cr:C ratio, resulting in diverse operative wear mechanisms, including micro-cutting and micro-fracture. Successful adjustment of the Cr:C ratio led to the attainment of a nearly eutectic HCCIs composition suitable for squeeze casting.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"202 ","pages":"Article 110315"},"PeriodicalIF":6.1,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142535903","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 method solved the problem of not being able to use CD technology on valve metal 6061 aluminum alloy and prepared a Ni/W coating on the surface of valve metal 6061 aluminum alloy. Energy dispersive spectroscopy (EDS)/X-ray diffraction (XRD)/Scanning electron microscopy (SEM) was used to characterize the micro-morphology and elemental composition of the prepared coatings. The friction and corrosion properties were tested by friction and corrosion experiments. The results show that the coating obtained after LR and CD has the advantages of high hardness, large thickness, good wear resistance, small friction coefficient and good corrosion resistance. By using LR technology for pre-treatment makes CD technology directly usable on the valve metal surface, which is of great significance for subsequent applications.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"202 ","pages":"Article 110287"},"PeriodicalIF":6.1,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142417095","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}

The as-synthesized MoS<sub>2</sub>/Bent nanohybrid was characterized by X-ray powder diffractometer, transmission electron microscopy, Fourier transform infrared spectroscopy, and the high temperature resistance and tribological properties of MoS<sub>2</sub>/Bent nanohybrid were evaluated in base slurry. The results show that the friction coefficient of MoS<sub>2</sub>/Bent nanohybrid drilling fluid before aging is reduced by 74 % and the wear rate is reduced by 97 % compared with the base slurry. After high-temperature aging at 240 °C, the friction coefficient is reduced by 77 % and the wear rate is reduced by 90 %.
