Abstract
A structural component made of a base metal composition on a nickel or cobalt basis is provided with a protective coating against oxidation, corrosion, and thermal fatigue. The protective coating and the base metal are made of chemically the same or identical material, whereby the bonding of the protective coating is increased, the tendency to crack is reduced, and the resistance to thermal fatigue is improved. The grain size of the coating is substantially smaller than the grain size of the base metal composition.
