[Abstract]:With the development of cutting technology in the direction of high speed, high efficiency, high precision, green and intelligence, cutting has put forward higher requirements for the performance of cutting tools and coatings. The quaternary hard coatings, represented by TiAlSiN coatings, have developed rapidly. The preparation process, structure and properties of monolayer TiAlSiN nanocomposite coatings were reviewed. According to the problems of low toughness and low bonding strength of TiAlSiN monolayer coatings, the necessity of studying the modification of TiAlSiN coatings was put forward. The preparation process, structure and properties of structural modification, composition modification and combination modification of TiAlSiN coatings are reviewed. It is pointed out that the transverse interlayer interface in nano-multilayer TiAlSiN coatings has a good hindering effect on the diffusion of atoms. The oxidation resistance of the coating is improved and the mechanical properties such as hardness of the coating are improved or decreased by the factors of the modulation layer composition and the modulation period of the multilayer structure. In this paper, the effect of alloying elements, such as Cu / Cu / Cr / V, on TiAlSiN coating is introduced. The main function of C element in the coating is to enhance the bonding between the coating and the substrate, and the hardness of the coating is reduced to some extent. It is put forward that it is one of the important research directions in the future to maximize the synergetic effect of adding elements and interlayer structure to obtain the best performance of nano-multilayer TiAlSiN based multicomponent coatings. In addition, the development direction of strengthening the toughness and bonding strength of TiAlSiN coating by pre-treatment and post-treatment was put forward.
