摘要

An environmentally resistant coating (34) for improving the oxidation resistance of a niobium-based refractory metal intermetallic composite (Nb-based RMIC) at high temperatures, the environmentally resistant coating (34) comprising silicon, titanium, chromium, and niobium. The invention includes a turbine system (10) having turbine components (11) comprising at least one Nb-based RMIC, the environmentally resistant coating (34) disposed on a surface (33) of the Nb-based RMIC, and a thermal barrier coating (42) disposed on an outer surface (40) of the environmentally resistant coating (34). Methods of making a turbine component (11) having the environmentally resistant coating (34) and coating a Nb-based RMIC substrate (32) with the environmentally resistant coating (34) are also disclosed.
