Abstract
A method for forming a high temperature coating includes forming a pre-sintered ceramic coating on a ceramic composite substrate. The pre-sintered ceramic coating includes a plurality of ceramic particles. The method further includes sintering at least a portion of the pre-sintered ceramic coating by heating the portion of the pre-sintered ceramic coating to a sintering temperature of the plurality of ceramic particles using joule heating. The sintering temperature is greater than about 1000 degrees Celsius (° C.).
Claims10
A method, comprising:
- forming a pre-sintered ceramic coating on a ceramic composite substrate, wherein the pre-sintered ceramic coating comprises a plurality of ceramic particles;
- contacting at least a portion of the pre-sintered ceramic coating with one or more contact electrical elements;
- delivering an electrical current through the one or more contact electrical elements to the ceramic composite substrate;
- and
- sintering at least the portion of the pre-sintered ceramic coating by heating the portion of the pre-sintered ceramic coating to a sintering temperature of the plurality of ceramic particles using joule heating induced in the ceramic composite substrate by the delivery of the electrical current through the one or more contact electrical elements to the ceramic composite substrate,
- wherein the sintering temperature is greater than about 1000 degrees Celsius (° C.).
