“…Phosphate-bonded coatings are used as antiwear materials to protect metal parts in aero-engines, pressurized gas engines, micro-combustion engines, and missile launchers. , However, under high loads and complex service conditions, the phosphate-bonded coating is prone to fracture, resulting in a reduction in mechanical properties and affecting the integrity and continuity of the lubricant film on the surface, thereby reducing the tribological performance of the coating . To solve this drawback, some functional fillers can be incorporated to improve the properties of the phosphate-bonded coatings.…”

To enhance the interfacial bond strength of carbon fiber (CF), graphene oxide (GO) was grafted onto the CF surface byγ-aminopropyl triethoxysilane, and CF modified with GO (CF-GO) was added into the phosphate-bonded coating as a reinforcement to improve the tribological properties of the coating. In addition, the evolution of the physiochemical structure of CF before and after the modification was investigated by Fourier transform infrared spectroscopy, X-ray diffraction analysis, X-ray photoelectron spectroscopy, and scanning electron microscopy. The results show that GO and CF are chemically bonded together, and the CF surface becomes rough due to the presence of GO, enhancing mechanical engagement to improve the interfacial bond between CF-GO and the coating matrix, which is improved by the CF pull-out test. Tribological tests were conducted to investigate the wear behavior of the coating. The friction coefficient of the coating decreases with the increase of CF-GO. Besides, the wear rate of the coating shows similar trends with the addition of CF-GO. The addition of 15 wt % CF-GO has reduced the coefficient of friction and wear rate of the coating by approximately 18 and 40%, respectively, when compared to those of the coating without GO-CF. The related mechanisms are also clarified.

“…[1][2][3][4][5] Chemically bonded phosphate ceramic coatings (CBPCs), as a kind of inorganic coating with great potential, has attracted great attention. [6][7][8][9] Recently, many studies have reported carbon nanotubes (CNTs) can act as a good nanofiller to enhance the wear and corrosion resistance property of the coating due to their unique features such as excellent mechanical, thermal and electrical properties. [10][11][12][13] Dong et al 14 investigated the influence of CNTs concentration on microstructure, micro-indentation hardness as well as friction behavior and anti-wear characteristics of the Ni-GO-CNTs composite coatings and found the wear resistance of Ni-GO-CNTs composite coating increases initially and then decreases with increasing CNTs concentration.…”

Chemically bonded phosphate ceramic coatings (CBPCs) with the addition of carbon nanotubes (CNTs) were prepared on mild steel (Q235) through the sol gel method. The wear and corrosion performance of CBPCs with the addition of CNTs were evaluated by tribological and electrochemical tests combining the analysis of microstructure, phase characterization, and curing behavior. Results indicate CNTs nanofiller significantly enhances the wear and corrosion behavior of CBPCs. The enhancement of wear performance for CBPCs with CNTs nanofiller is produced by the CNTs effectively hindering dislocation movement through the coating and substrate system and the occurrence of plastic deformation owing to their remarkable mechanical and lubricating properties. The enhancement of corrosion performance for CBPCs with CNTs nanofiller is due to the CNTs helping CBPCs to develop a denser and more compact microstructure, which contributes to prolonging the electrolyte diffusion path. In addition, CNTs exhibit excellent hydrophobicity and can absorb oxygen molecules, which prevents the corrosion process on the anode and cathode sections of coating and substrate system.

On the basis of the complex environment of port terminals, the corrosion resistance of coatings for accompanying metal facilities is a primary factor that needs to be considered. This study prepared polydopamine‐modified graphene oxide loaded with silicon dioxide (PGO@SiO2) functional filler, which was incorporated into polyester resin (PR) by extrusion mixing. The PGO@SiO2/PR composite coating was obtained by electrostatic spraying and high‐temperature curing. Fourier transform infrared spectroscopy, x‐ray diffraction, and other results confirmed the successful preparation of the PGO@SiO2 functional filler. In addition, contact angle, adhesion, and corrosion resistance tests were performed on the composite coating. Compared with pure PR coating, the surface hydrophobicity and adhesion of the composite coating were significantly improved compared with the pure PR coating. Furthermore, the electrochemical impedance spectroscopy of the carbon steel substrate composite coating confirmed that after immersion in salt solution, the low‐frequency impedance modulus of the composite coating could be maintained at 8.63 × 108 Ω·cm2, which was more than two orders of magnitude higher than that of the pure PR coating. Thus, PGO@SiO2 could significantly enhance the corrosion resistance of the PR coating and hinder the infiltration of corrosive media. It has broad prospects for engineering applications because of its excellent anticorrosive performance.
