Abstract
A turbine blade and a method for its production. In order to protect the turbine blade from being damaged by particles carried in the gas, surfaces of the turbine blade are melted down to a predetermined depth in order to form a defined amorphous region on a crystalline structure of a base material. The surfaces are then cooled down at a predetermined temperature reduction rate per unit time.
