Abstract
This is an improved process for fabricating a turbine blade for use in land based or marine combustion turbines and in particular is a thin ceramic coating applied to at least the portion of the blades which is designed to operate in the 1100.degree.-1500.degree. F. temperature range and especially in turbines designed to be useable with contaminated fuels. The invention utilizes a 1-4 mil thick ceramic coating on at least a portion of the blade designed to operate in the 1100.degree.-1500.degree. F. temperature range and utilizes a process in which the blade is controlled to a temperature of at least 1200.degree. F. during the application of the ceramic coating.
