The present inventions incorporate self-healing mechanisms into current and future EBC systems. Such approaches have the potential to form environmental protection materials (i.e. thermally grown silicate compositions) in-situ to enable the ability to provide environmental protection to SiC based ceramics even in the event that cracks or voids form from within the EBC layer. In this disclosure, novel, self-healing EBC systems are disclosed along with coating synthesis techniques required to deposit the materials, microstructures and architectures. This research is anticipated to result in a thermal/environmental barrier coating system (T/EBC) that provides improved durability over current coatings. These advancements will aid the use of Si-based ceramics in a range of high temperature applications such a gas turbine engines and heat exchangers. These advances will not only benefit military engines, but also commercial and industrial engines requiring greater performance.
