Abstract

To further enhance the lubrication performance of composite coatings, this study employed an electrospray masking in-situ forming technology to fabricate textured (CF_x)_n/CaF₂/C-ZrO₂/TiO₂ composite coatings. Their microstructures, mechanical properties, and reciprocating wear behaviors were investigated. Results showed that this technique could directly create high-quality chessboard microtextures during coating fabrication, integrating multiple materials on a single surface. Compared to non-textured LT samples, the CBM samples demonstrated enhanced coating-substrate adhesion strength (132 N, increased by 11 %), low friction coefficient (~0.09, reduced by 18.2 %) and wear rate (~1.86 × 10⁻⁷ mm³·N⁻¹·mm⁻¹, reduced by 42.4 %) at 25 °C, and excellent self-lubricating performance across 200–600 °C. Mechanism analysis revealed that the chessboard structure exhibited a synergistic effect with the coating materials.

期刊介绍： Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance: A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting. B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
