Abstract Nine organic compounds were utilized as model lubricants to investigate the impact of functional groups on tribological performances. Nonanoic Acid with carboxyl showed best lubrication properties, and fluid film tribofilm coexistent in its friction test, bringing a low coefficient wear rate. In addition, lubricant corresponded high adsorption energy density theory (DFT) calculations. And forming large surface displayed small rate test. Moreover, energies positively correlated...
Graphene is widely applied as lubricating materials owing to its superior tribological performances. However, complex synthesis process causes environmental pollution and increases production cost. In the current work, we developed a facile strategy construct sustainable lubricant system by generating graphene in situ, which avoided complicated synthetic process. The novel constructed introducing cyclopropanecarboxylic acid (CPCa) metal particles (nickel copper) into base oil. CPCa molecules...
Abstract Diamond-like carbon (DLC) films are deposited on rubber surfaces to protect the components, and surface pretreatment of substrates prior film deposition can improve adhesion between DLC rubber. Thus, principal purpose this work concentrates determining effects argon (Ar), oxygen (O 2 ), nitrogen (N hydrogen (H ) plasma pretreatments friction performance (DLC/rubber). The results indicated that Ar promoted formation a compact layer surface. By contrast, massive fillers were exposed...
• Three kinds of ultrathin two-dimension metal-organic framework (2D-MOF) nanosheets with different metal ions (Ni 2+ , Zn and Cu ) were successfully synthesized. Ni-MOF as a new lubricating oil additive exhibit the best dispersion stability, relative absorbance is high 0.85 after five days. The addition 0.1 wt% obtains tribological properties, reducing friction by 33.2 ± 12.4 % wear 98.7 0.14 compared pure base oil. excellent lubrication performance originates from their interlayer sliding...
High performance solid lubricant materials with long wear life remain as one of the challenges in space technology. It is great significance to lower film's friction and prolong its service vacuum. Hydrogenated fullerene‐like carbon film produced by dc‐pulsed power source behaves ultralong (≫1.8 × 10 5 cycles) ultralow rate (2.2 −8 mm 3 Nm −1 ) well low (≈0.14) high vacuum (2.3 −4 Pa). To understand reason, interfacial structural evolution investigated after steady state achieved. By...
Abstract Fluorine-incorporated hydrogenated fullerene-like nanostructure amorphous carbon films (F-FLC) were synthesized by employing the direct current plasma enhanced chemical vapor deposition (dc-PECVD) technique using a mixture of methane (CH 4 ), tetra-fluoromethane (CF and hydrogen (H 2 ) as working gases. The effect fluorine content on bonding structure, surface roughness, hydrophobic, mechanical, tribological properties was systematically investigated Fourier transform infrared...
