“…Tribopair surface abrasion refers to the mechanical wear caused by the carbide, nitride and oxide hard points of the workpiece, the built‐up edge, etc., which abrade the surface of the tool and scratch out a strip of grooves 51 . The characterisation results show that from the conditions of 2.0 m/s or 4 MPa, regardless of the increase in velocity or load, obvious wear track and spalling can be observed from the wear morphology and the wear cross‐sectional area is more than 7000 μm 2 .…”

In this work, the tribological properties of a novel iron‐based self‐lubricating composite as the tribopairs of a plunger pump were systematically studied on an end‐face tribometer, and the tribological mechanism was also revealed. The results show that the wear mechanism of the composite can be ascribed to adhesive wear when the sliding speed is lower than 1.5 m/s. As the sliding speed increases from 1.5 to 2.0 m/s, the wear type transforms to oxidative wear due to the increase of tribo‐oxidation. In addition, the failure criteria of the tribopair composite materials are summarised. When the average coefficient of friction is greater than 0.04, or the wear rate is greater than 9.66 μm3/(N m), the tribopair fails. This offers a valuable reference for industrial application of the tribopairs made from the iron‐based self‐lubricating composite.

“…The lubricant film cannot completely isolate the two contact surfaces; hence the full ceramic ball bearing is in a mixed lubrication state [28]. There are micro-bulges on the balls and the raceway, and they directly rub and collide with each other [29]. When the balls rotate in the cage under the action of friction, the vibration of the bearing increases rapidly and reaches a peak value.…”

As a new high-end bearing product, full ceramic ball bearings are favoured in a variety. However, there have been few studies on the lubrication of full ceramic ball bearings. The purpose of this study is to reveal the relationship between the vibration and temperature rise of full ceramic angular contact ball bearings and the lubricant viscosity, and to improve the service life of the bearings. In this study, the effects of lubricant viscosity on the vibration and temperature rise of silicon nitride full ceramic angular contact ball bearings under different axial loads and rotation speeds were tested. Herein, a mathematical model of oil lubrication suitable for full ceramic ball bearings is established and the relationship between the lubricant viscosity, lubricant film thickness, outer ring vibration and temperature rise of the bearing is analyzed. It was found that the vibration and temperature rise first decrease and then increase with the increase of lubricant viscosity. In this range, there is an optimal viscosity value to minimize the vibration and temperature rise of the full ceramic angular contact ball bearing. The contact surface wear of the full ceramic angular contact ball bearing varies greatly under different lubricant viscosities. There is no obvious wear on the contact surface under optimal viscosity, and the service life of the bearing is greatly improved. These results can play an important role in revealing the lubricant mechanism of full ceramic ball bearings and improving their service life under optimal lubrication.

“…Marine engineering equipment materials will be subject to a variety of loads during the installation and service period, and will also be subject to corrosion caused by seawater or/and oil and gas media, as well as the role of low or high-temperature environments that may be encountered. And 316L stainless steel has a very wide range of applications in marine engineering equipment because of its excellent corrosion resistance, good resistance to chloride erosion, and high temperature and pressure resistance [1,2]. However, due to the low surface hardness and load-bearing capacity of 316L stainless steel, poor wear resistance and other issues limit the friction-matching parts' application [3].…”

The laser surface texture process will inevitably produce the edge of material surface texture bulges. Currently, laser processing bulges are generally polished directly, but this method ignores its impact on the friction pairs. In this paper, the tribological properties of polished and unpolished textured surfaces were investigated under dry friction, oil lubrication, and seawater lubrication conditions using three shapes of texture (grooves, square pits, and round pits) prepared on the surface of 316L stainless steel. The results show that the polished surface of 316L stainless steel texture increases wears, and the friction mechanism is mainly adhesive wear, while the unpolished surface of the texture has less wear, and the friction mechanism is mainly abrasive wear. The method and principle of using machining bulges to improve the wear resistance of friction pairs are discussed to address the differences in the tribological performance of entire friction pairs due to the influence of machining bulges of different shapes of texture.
