High temperature-resistant corrosion protection coating on a component, in particular a gas turbine component

A protective coating applied on a component formed of a nickel-based or cobalt-based superalloy, the protective coating comprising in percent by weight:

• 25 to 40% nickel, 28 to 32% chromium, 7 to 9% aluminum, 1 to 2% silicon, 0.3 to 1% of at least one reactive element of the rare earths, an addition of from 1 to 15% rhenium, impurities, and a remainder of at least 5% cobalt.

A protective coating composition resistant to corrosion consisting essentially of the following elements (in percent by weight):

• approximately 30% nickel, approximately 29 to 31% chromium, approximately 8% aluminum, approximately 1.5% silicon, 0.3 to 1% of at least one reactive element of the rare earths, selectively from 0 to 15% of at least one of the elements selected from the group consisting of rhenium, platinum, palladium, zirconium, manganese, tungsten, titanium, molybdenum, niobium, iron, hafnium, and tantalum, impurities, and a remainder of at least 5% cobalt.
