  • Process and device for determining the quality of a weld seam or a thermal spray coating and application
    Publication number: 20060279731
    Abstract: In material depositing processes such as welding or thermal spraying the large variety of processes and material parameters necessitate a broad range of the resulting characteristics of the applied material. The task of the present invention is comprised of providing a process and a device for determining the quality of specific layer characteristics, in particular their adhesion or strength of joining to the base material. This task is solved thereby, that as the quality characteristic there is employed the degree of mixing of the applied material with the base material.

  • Method for monitoring plasma or flame-spray processes
    Patent number: 6797939
    Abstract: A method for measuring characteristic properties of a plasma beam in a thermal spraying process, wherein the spraying materials are fed into the plasma (1) and the luminous radiation emitted by the plasma (1) is reproduced on optical fibers (2). The luminous radiation is reproduced on the one end (2a) of the optical fibers (2) arranged in a one-dimensional or two-dimensional array (6). Spectral analysis of the luminous radiation transmitted in the optical fiber (2) is accomplished with a spectrometer (3) arranged at the other end (2b) of an optical fiber (2). The frequency spectrums are analyzed in a processor (5) to determine the contemporaneous condition of the spraying process.

  • Method and apparatus for continuously removing nitrogen oxides in exhaust gases of internal combustion engines
    Patent number: 5782085
    Abstract: The invention relates to a method for continuously removing nitrogen oxides in exhaust gases of internal combustion engines containing an excess of oxygen by feeding a reactive nitrogen-containing plasma jet into the exhaust gas stream, wherein the plasma jet is generated by electromagnetic high-frequency fields.
