Abstract (en)

[origin: EP1676938A1] Production of metal components with a surface oxide layer of one or more metal oxides Me1 yMe2 zO x, Me1O x or Me2O x, where a surface region is treated to produce impoverishment in at least one of elements Me1 or Me2 forming the above oxides. An independent claim is included for a component, e.g. a turbine, especially gas or steam turbine, especially a turbine blade or heat shield element.
