Crack-resistant environmental barrier coatings
Methods suitable for reducing corner cracking of environmental barrier coating systems. The methods include forming at least one layer of a first portion of the environmental barrier coating system on at least a first region of the component, performing a first heat treatment, forming at least one layer of a second portion of the environmental barrier coating system on a second region of the component, and performing a second heat treatment to the component. Edges of the first portion and edges of the second portion form an angle of at most 60° with respect to a surface of the first region of the component. During the second heat treatment, the second portion of the EBC system expands and the expansion of the second portion of the EBC system is at least partially constrained by the first portion of the EBC system to reduce tensile interfacial stresses in the EBC system.
