  • Publication number: 20230021394
    Abstract: Disclosed is a thin film stress control-based coating method for large-area coating. The method uses a two-step coating process in which a first coating layer that is a relatively low-hardness layer is primarily formed on a base member and a second coating layer that is a relatively high-hardness layer is secondarily formed on the first coating layer. The method can form a high-density coating structure that is hardly peeled off over a relatively large area compared to conventional coating methods by suppressing internal stress of the coating layers of the coating structure. Further disclosed is a coating structure manufactured by the same method.
