    摘要: A coating composition for superalloy structural parts, especially, for gas turbine vanes and blades, which has high resistance to oxidation and corrosion and has excellent mechanical behavior. The coating preferably comprises: 18 to 28 wt % of Co; 11 to 15 wt % of Cr; 11.5 to 14 wt % of Al; 1 to 8 wt % of Re; 1 to 2.3 wt % of Si; 0.2 to 1.5 wt % of Ta; 0.2 to 1.5 wt % of Nb; 0.3 to 1.3 wt % of Y; 0 to 1.5 wt % of Mg; 0 to 0.5 wt % of a total of La and La-series; 0 to 0.1 wt % of B; less than 0.1 wt % of Hf; and less than 0.1 wt % of C. The balance of the coating is Ni. A total of Y, La, and La-series is from 0.3 to 2.0 wt %, and a total of Si and Ta is equal to or less than 2.5 wt %.

    摘要: In a method of spatially detecting the chemical composition of nonmetallic components on a surface which is subsequently to be coated with a metallic and/or ceramic and/or organic layer, a laser optical device is provided. The turbine part is irradiated with monochromatic irradiation at a first wavelength (λin) with the laser optical device. Radiation is detected which is emitted by the surface at a second wavelength (λout) which is longer than the first wavelength (λin).
