摘要:
Improved compositions are described for the protection of gas turbine parts at elevated temperatures. The compositions are of the MCrAlY type, wherein M is Nickel, or Nickel in combination with cobalt and/or iron. The compositions further comprise a lanthanide, a group 4 metal selected from hafnium, zirconium, titanium, or a combination of these, and optionally, a group 14 element selected from silicon and/or germanium. The combination results in improved Al retention properties. Also disclosed herein are articles comprising the coatings.
