    摘要： It is disclosed a method of determining the exposure temperature of Al and Cr of a γ/γ′ MCrAlY-coating after the use in a high temperature environment, the γ/γ′ MCrAlY-coating exhibiting a non-equilibrium γ/γ′-microstructure at a temperature lower than the temperature during operation and the depletion of chromium from the γ/γ′-MCrAlY-coating still allows the α-Cr phase to form. The coating conductivity and permeability by means of a multifrequency eddy current system is measured at different locations of the component and from the measured conductivity and permeability the exposure temperature of said different locations of the components is determined.

    摘要： It is disclosed a method of applying a coating (12) with a controlled laser metal forming process. A light source with a specific power and a signal capturing apparatus is moved over an article (1) to form locally a melt pool (7) on the surface (5) of the article (1) to which a coating powder (8) is injected. An optical signal (13) is captured from the melt pool (7), and the monitored optical signal (13) is used for the determination of the temperature and temperature fluctuations of the melt pool (7). Furthermore, a control system (16) is used to adjust at least one process parameter such as the power of the light source to obtain desired melt pool properties. Subsequently the melt pool (7) solidifies. The high degree of control over the microstructure provides an efficient tool for generating laser metal formed hard coatings (12) with optimised wear properties.

    摘要： In a heat treatment process for a single-crystal or directionally solidified material body comprising a nickel-based superalloy, the material body is solution-annealed and then at a first temperature γ′ particles of greater than 1 μm are precipitated in a proportion by volume with Vtot−V1 of less than 50%, where Vtot is the total amount of γ′ particles after complete heat treatment and V1 is the proportion of the γ′ particles which is greater than 1 μm, and at least at a second temperature ‘γ’ particles of less than 1 μm are precipitated. The γ′ particles are preferably precipitated in a size of 2 pin or more with a proportion by volume of 0.25

    摘要： A leaf seal for sealing a shaft rotating about an axis, in particular in a gas turbine, includes a plurality of spaced-apart leaves arranged in a concentric circle around the axis and fixed in position by brazing, the leaves having surfaces oriented essentially parallel to the axis. The leaves are brazed to one another via intermediate spacers made of a brazing foil, so that a brazed joint is produced by brazing alloy from the brazing foils. The brazing temperature may be set to an optimum value just above the solidus temperature of the brazing foil, at which partial melting of the brazing foil occurs and penetration of liquid brazing alloy into the gap between the leaves is avoided.
