A Thermal Barrier Coating Structure Having Vertical-type Cracks and A Thermal Barrier Coating Manufacturing Method thereof

摘要

The present invention relates to a thermal barrier coating and a method of manufacturing microstructures having vertical cracks, the present inventors train consists of waste material coating layer is formed, the base metal layer and formed of a metal material, the bond coat layer for bonding the base material layer and the ceramic thermal barrier coating layer, is bonded to the outer surface of the base material layer ceramic coating layer for shielding heat (top coat layer ); and configuration, including, and in the outer surface to the top coating layer characterized in that a crack formed in the inside. Then, the manufacturing method of another embodiment of the thermal barrier coating layer is formed material of the present invention, a first step of blasting the base material, and a second step of forming a coating layer by using a material to be coated on the base material, the coating layer is formed a third step of cooling the base material to be; Then, the plasma heat-treating the coating layer to the surface of the cooling tower can be configured to include a fourth step of forming a crack in the top coat layer. ;
