“…They are high in hardness, low in density, excellent in thermal and chemical stability, and outstanding in corrosion resistance, Moreover, these ceramics have seen wide-ranging industrial applications, including use in high-speed cutting tools, engine parts, sealing modules, bearings, and corrosion-resistant components [2][3][4][5]. Wu et al [6] found a WC-10Co-4Cr/Si 3 N 4 tribopair with a friction coefficient of 0.09 and a wear rate lower than 9 × 10 −6 mm 3 N −1 m −1 in natural seawater, attributing this to Si 3 N 4 tribochemical reaction. Liu et al [7] conducted research on the tribological behaviors of Si 3 N 4 /AISI316 tribopair in seawater conditions.…”

This paper concerns a comparative study on the tribological properties of Si3N4-10 vol% hBN bearing on GCr15 steel under seawater lubrication and dry friction and fresh-water lubrication by using a pin-on-disc tribometer. The results showed that the lower friction coefficient (around 0.03) and wear rate (10−6 mm/Nm) of SN10/GCr15 tribopair were obtained under seawater condition. This might be caused by the comprehensive effects of hydrodynamics and boundary lubrication of surface films formed after the tribo-chemical reaction. Despite SN10/GCr15 tribopair having 0.07 friction coefficient in the pure-water environment, the wear mechanismsits were dominated by the adhesive wear and abrasive wear under the dry friction conditions, and delamination, plowing, and plastic deformation occured on the worn surface. The X-ray photoelectron spectroscopy analysis indicated that the products formed after tribo-chemaical reaction were Fe2O3, SiO2, and B2O3 and small amounts of salts from the seawater, and it was these deposits on the worn surface under seawater lubrication conditions that, served to lubricate and protect the wear surface.

“…It is demonstrated that super-low friction coefficient can be detected with a 2 N applied load. Wu et al [13] studied the tribological performance of WC-10Co-4Cr coating sliding against Si 3 N 4 lubricated with silt-laden water. It was concluded that the deposition of SiO 2 and Si(OH) 4 layers produced by the tribo-chemical reaction between water and Si 3 N 4 can significantly reduce the friction and wear of the friction pair.…”

To improve the abrasion resistance performance of the critical tribopairs within water hydraulic piston pumps, tribological characteristics of the stainless steel 17‐4PH and 17‐4PH coated with Cr3C2‐NiCr, WC‐10Co‐4Cr, Cr2O3 and Al2O3‐13%TiO2 sliding against carbon fiber reinforced polyetheretherketone (CF‐PEEK) composite under water‐lubricated condition were experimentally studied using a pin‐on‐ring test bench with different working conditions. It has been demonstrated by the experimental results that the tribological behaviors of CF‐PEEK/cermet coatings tribipairs were better than that of CF‐PEEK/17‐4PH tribopair under water lubrication. However, the Cr3C2‐NiCr coating could be damaged under high rotational speed. Due to the reaction film produced by the Al2O3‐13%TiO2 and water, the CF‐PEEK/Al2O3‐13%TiO2 material combination exhibits more excellent tribological behaviors than other tribopairs lubricated with water, and could preferentially be used in water hydraulic piston pumps.

Effect of Diamond Nanoparticle on the Friction Property of Sliding Friction Pair With Molecular Dynamics Simulation

2019

Effect of the diamond nanoparticle on the friction property of the sliding friction pair is investigated using the molecular dynamics simulation. A molecular dynamics simulation model without the diamond nanoparticle is also set up. The simulation is conducted at an external load of 60 nN. The results confirm that adding diamond nanoparticle can improve the friction property. With increasing the diameter, the angular velocity, and the indentation depth decrease inversely. Also, when the diameter varies from 32.13 Å to 49.98 Å, the friction force, and the contact area are both inversely proportional to 3.6 power of the diameter. The relationship between friction force and contact area shows a linear increase law, which indicates that friction force is affected by the contact area.
