    摘要: A system comprises a plurality of components disposed to define a gas path. At least one component comprises a silicon-bearing substrate over which is disposed a coating, and the coating comprises a recession-resistant material exposed to the gas path. A silicon source is disposed in fluid communication with the gas path and is configured to be delivered to the gas path to maintain, in gas flowing in the gas path over the coating, a silicon mass concentration in the range from about 1.8×10−4 parts per million to about 1 part per million An associated method comprises directing a combustion gas flow within a gas path, the gas path defined by a plurality of components, wherein at least one component comprises a silicon-bearing substrate over which is disposed a coating, the coating comprising a recession-resistant material exposed to the gas path; and delivering a silicon-containing material to the gas flow from a silicon source disposed in fluid communication with the gas path to maintain within the gas flow over the coating, a silicon mass concentration in the range from about 1.8×10−4 parts per million to about 1 part per million.
