An environmentally resistant coating comprising silicon, titanium, chromium, and a balance of niobium and molybdenum for turbine components formed from molybdenum silicide-based composites. The turbine component may further include a thermal barrier coating disposed upon an outer surface of the environmentally resistant coating comprising zirconia, stabilized zirconia, zircon, mullite, and combinations thereof. The molybdenum silicide-based composite turbine component coated with the environmentally resistant coating and thermal barrier coating is resistant to oxidation at temperatures in the range from about 2000° F. to about 2600° F. and to pesting at temperatures in the range from about 1000° F. to about 1800° F.
A turbine system having at least one turbine component, said turbine component comprising:
An environmentally resistant coating for a molybdenum silicide-based composite substrate, said environmentally resistant coating comprising between about 43 and 67 atomic percent silicon;
A turbine system having at least one turbine component, said turbine component comprising:
A method of making a turbine component comprising a molybdenum silicide-based composite and having an environmentally resistant coating disposed on the surface of the turbine component, the environmentally resistant coating comprising silicon, titanium, chromium, niobium, and molybdenum, the method comprising the steps of:
A method of coating a molybdenum silicide-based composite substrate with an environmentally resistant coating, the environmentally resistant coating comprising silicon, titanium, chromium, niobium, and molybdenum, the method comprising the steps of:
