Ultrafast high temperature sintering (uhs) systems and methods for fabricating environmental-thermal barrier coatings

A method comprising:

• (a) providing one or more first precursors over a surface of a component to be coated;
• (b) providing a heating element over the one or more first precursors, the heating element substantially conforming to a shape of the component surface;
• and
• (c) sintering the one or more first precursors to form a first layer of an environmental-thermal barrier (ETB) coating over the component surface by subjecting the one or more first precursors to a sintering temperature in a range of 500-3273 K, inclusive, for a duration of less than or equal to 10 minutes,
• wherein the sintering temperature is generated by passing an electric current through the heating element to cause Joule heating of the heating element.
