Summary: This study reports the development of a superlubricious epoxy resin composite coating (EP/PDMS) containing polydimethylsiloxane (PDMS) for the first time. PDMS self-aggregated into nanoparticles in the epoxy resin matrix, enhancing the tensile toughness of the coatings. The EP/PDMS composite coatings exhibited stable superlubricity and high wear resistance when sliding against different bearing materials. Remarkably, under ambient air with a high relative humidity of 70%, the EP composite coating with a small content of PDMS (3.0 wt%) achieved an exceptionally low friction coefficient of 0.007, and the average wear rate of the EP/PDMS composite coating was as low as 2.76 x 10-7 mm3/N.m despite its low hardness.

Summary: The study investigated the mechanical and tribological properties of an epoxy matrix filled with different graphitic particles deposited on an aluminum substrate using the electrostatic spray technique. The results showed that adding crushed graphite improved the dynamic friction performance of the epoxy, while epoxy filled with received graphite had a lower wear rate. Additionally, it was observed that the smaller the particle size, the more significant the reduction in dynamic friction.

Summary: By incorporating differently sized cubic boron nitride (CBN) particles into epoxy resin (EP) composite coatings on stainless steel, the tribological and anti-corrosion properties of the coatings can be enhanced. The optimal tribological performance for dry sliding is achieved when the additive proportion of microsized and nanosized CBN particles is 1:1, while the best tribology and corrosion resistance performance in seawater conditions is achieved when the ratio is 2:1. The microparticles play a more important role in load-carrying capacity under seawater lubrication, while a more compact structure improves the electrolyte barrier ability of the composite coatings.

Summary: In this study, an aluminium oxide-phenolic resin (Al2O3-PF) composite coating was successfully deposited on the surface of an epoxy resin matrix composite using supersonic plasma spraying. The coating significantly improved the ablation resistance of the composite material. The presence of unmelted Al2O3 particles in the coating resulted in the formation of pores, while the continuous heat accumulation during spraying caused cracks in the matrix, reducing its structure and performance.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
