COATING FOR GAS TURBINE COMPONENTS, AND METHOD AND DEVICE FOR PROVIDING A COATING

摘要

The invention relates to a coating, particularly for gas turbine componen ts made of a superalloy, wherein the same has an outer layer and an inner la yer. According to the invention the outer layer constitutes 10% to 60% of th e overall coating, wherein the outer layer is substantially made of a ß-NiAl phase having an Al proportion of between 23 and 35 weight-%, wherein the in ner layer constitutes 90% to 40% of the overall coating, and wherein the inn er layer is substantially made of a .gamma.-NiAl phase having an Al proporti on of a maximum of 15 weight-%.
