This invention discloses a method for in-situ generating a highly bonded Cr2O3 interface to improve the thermal shock resistance of coatings. The method involves a coating preparation technique, particularly in the process of preparing a coating on a Cr-containing metal substrate, where an electric field of specific intensity is applied during the high-temperature heat treatment stage. By utilizing the electric field to induce the outward diffusion of Cr ions and the inward migration of oxygen ions in the substrate, a dense Cr2O3 transition layer is in-situ induced at the interface between the coating and the metal substrate. This transition layer effectively alleviates the problem of thermal expansion coefficient mismatch between the ceramic coating and the metal substrate, releases interfacial thermal stress, and significantly enhances the bonding strength of the coating. This invention achieves control over the thickness of the transition layer by adjusting the current intensity. Experiments show that this method can significantly suppress the generation of microcracks during thermal shock cycling, thereby greatly improving the thermal shock resistance of the coating and effectively solving the problem of easy cracking and peeling of oxide coatings during high-temperature thermal cycling.
