“…According to the hardness (H), the coatings are divided into three groups, as shown in Figure 5: (1) Hard coatings with H < 40 GPa; (2) Superhard coatings with H ranging from ~40 to ~80 GPa; (3) Ultrahard coatings with H > 80 GPa. It has been found that there are two groups of superhard nano-composite coatings [38,44,45]:…”

Transition metal nitride (TMN) films with excellent hardness and lubricating performance are versatile low dimension materials, which are widely used in various fields including industries, transportation, aerospace, and so on. This paper introduces one film design strategy and provides a review of the mechanisms for strengthening and lubricating nitride films. The design strategy refers to two aspects which determine the structures, the performance, the components, and the chemical constitutions of nitride films The strengthening mechanisms of nitride films are then illuminated in detail, including the solid solution effect, the grain size effect, the secondary phase effect, the stress or stress field effect, the template effect, and the valence electron concentration effect. Five lubricating mechanisms are next summarized, including the easy-shear nature, the tribo-chemical reactions, the lubricious fluorides, the textured contact surface, and the synergistic effect. This paper aims to give a comprehensive introduction for understanding the mechanisms of strengthening and lubrication of nitride films for students and researchers, as well as to understand the current research progress in nitride films for exploring research gaps.

Previous studies have broadly dealt with TiAlSiN coatings that exhibit promising characteristics as surface protective layers for antiwear and antioxidation applications. In this regard, revealing the correlations among coating composition, structure, and properties is vitally important for developing advanced TiAlSiN coatings. The present work addresses the issue by studying the structure and properties of TiAlSiN coatings by tailoring Al/(Al + Ti) ratios. To this end, TiAlSiN coatings are produced by arc deposition with the Al/(Al + Ti) ratios of 0.31, 0.42, 0.51, and 0.62, respectively. The results show that, when the Al/(Al + Ti) ratio ranges from 0.31 to 0.51, the phase structure is mainly TiN phase, and the hardness, wear resistance and oxidation resistance of the films are increased with the rise in the Al/(Al + Ti) ratio. When the Al/(Al + Ti) ratio reaches 0.62, the oxidation resistance of the coating does not improve significantly, while the mechanical and wear properties of the coating are deceased due to the formation of w‐AlN phase. Therefore, the appropriate Al/(Al + Ti) ratio at 0.51 provides overall improvements including mechanical properties, and wear and oxidation resistances under operation conditions. These findings show that optimizing the Al/(Al + Ti) ratio is a promising way to develop TiAlSiN coatings with advanced structure and properties.
