摘要：
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.
