Methods for producing a high temperature oxidation resistant coating on a superalloy component and the coated superalloy component produced thereby are provided. Aluminum or an aluminum alloy is applied to at least one surface of the superalloy component by electroplating in an ionic liquid aluminum plating bath to form a plated component. The plated component is heat treated at a first temperature of about 600° C. to about 650° C. and then further heat treated at a second temperature of about 700° C. to about 1050° C. for about 0.50 hours to about two hours or at a second temperature of about 750° C. to about 900° C. for about 12 to about 20 hours.

A composite sealant for in-situ sealing a fuel cell stack is provided. A paste of the sealant mixture is initially formed by mixing a glass precursor powder and a reacting filler material. The sealant mixture paste is applied to selected sealing locations of the fuel cell stack. The sealant mixture paste is then transformed into a composite sealant material to seal the selected sealing locations by heat treatment in air to about 900° C. The composite sealant material comprises a glass matrix phase and a reinforcing phase including a plurality of interlocked elongated single crystal grains. The reacting fillers modify the CTE and significantly improve the gap filling capacity of the composite sealant material and provide superior pressure containment capability at elevated temperatures.
