Summary: This study investigated the impact of organic friction modifiers and ZDDP on boundary lubrication of steel surfaces, finding that PFMs are generally more effective than OFMs in eliminating the boundary regime. Both OFMs and PFMs had a negative effect on the anti-wear performance of ZDDP, possibly due to preferential adsorption or decomposition products.

Summary: The friction and wear behavior of WC based cemented carbides ring-ring samples were tested in different water environments. The results show that the friction coefficient decreases exponentially with increasing load for all sample pairs. The wear rate of the stationary ring is about 3 times that of the matching rotary ring, regardless of the water lubrication medium. The corrosivity of artificial seawater can aggravate the peeling of WC particles. These results provide a meaningful reference for the design of cemented carbide bearings used in water lubrication environment.

Summary: This study presents an improved actuator based on IPMC and CMWCNTs, where the nanoscale decoration of CMWCNT materials effectively enhances the electronic, mechanical, and driving performance of the actuator, resulting in significant improvements in output force and sensitivity. This enhancement is attributed to the acceleration of hydrated cations movement by carboxylic groups. Moreover, the IPMC-embedded nanotube design shows great potential for the development of robotic-assisted manipulations, such as biomedical robots and microelectromechanical systems.

Summary: Currently, the lubricating properties of polymers such as polyethylene glycol (PEG) and chitosan (CS) are widely studied. In this study, different mass ratios of powder combinations are obtained by changing the mass of CS, and polymer films are obtained by hot pressing on the surface of the aluminum disk after microarc oxidation (MAO). The tribological properties of the composite film are evaluated and the results show that the composite film with a mass ratio of 5:5:1.5 of polyvinyl alcohol (PVA), PEG, and CS has excellent lubrication performance.
