| Summary: | The paper presents the fabrication of chessboard-structured (CFx)n/CaF2/C–ZrO2/TiO2 lubricant-hard alternate coatings by electrospray mask in-situ forming technique. The influence of the coating's structure and components on microstructure, film-substrate adhesion strength, and reciprocating wear performance were studied. The results showed that the chessboard structure of the hard coating had a high surface energy of 83.45 mJ/m2, which enhanced the adhesion of the lubricant coating. The addition of graphite (C) improved the uniformity, thermal stability, and lubrication of the (CFx)n/CaF2 lubricant coating. Within the 25–600 °C temperature range, the chessboard-textured (CFx)n/CaF2/C–ZrO2/TiO2 lubricant-hard alternate coating all exhibited low friction coefficients, which attributed to the synergistic effect between chessboard structure and coating material. |
