Thermal spraying ceramic coating has excellent wear resistance, corrosion resistance, thermal insulation and other properties, which can give metal/alloy parts good extreme environmental service properties. It is one of the best choices for surface protection of extreme environmental service parts, and is widely used in mechanical parts in aerospace, military, transportation and other fields. In order to reduce the stress gradient between the substrate and the ceramic coating, the alloy/ metal bond-coats is usually prepared on the surface of the substrate. Because the thermal expansion coefficient, elastic modulus and crystal structure of ceramic top-coats are quite different from the metal/alloy bond-coats, the interface mechanical properties directly determine the service life of the entire material, which has become one of the bottlenecks restricting the rapid development of this field. Based on this, the recent research progress of the interface between the thermal spraying bond-coats and the ceramic top-coats is reviewed. The coupling interface of the double layer structure coating, the insitu oxide nailing interface of the double layer structure coating, the continuous gradient transition interface that blurs the interface and the optimized nanocomposite continuous gradient transition interface are introduced. The coating bond strength with different interface structures is compared. Finally, the outstanding problems and the future development direction of the interface between thermal spraying bond-coats and ceramic top-coats are summarized.
