The present invention relates to an overlay coating which has improved strength properties. The overlay coating comprises a deposited layer of MCrAlY material containing discrete nitride particles therein. The nitride particles are present in a volume fraction in the range of 0.1% to 15.0% and have a particle size in the range of from 0.1 microns to 10.0 microns. The coating may also have oxide particles dispersed therein.

The present invention relates to an improved tool for holding at least one turbine blade having a platform during the application of a coating to underplatform areas of the at least one turbine blade. The tool includes at least one fixture for holding the at least one turbine bladed during the coating application. The at least one fixture has a base receptacle for receiving the at least one turbine blade and a cover for the base receptacle. Each of the base receptacle and the cover has an opening which corresponds in shape to each of the underplatform areas to be coated.
