  • METHODS OF FABRICATING STRUCTURAL ELEMENTS
    Publication number: 20100207299
    Abstract: A method of fabricating structural elements on the surface of a component is provided. The structural elements are configured to modify flow of a fluid passing over the surface. Conveniently, the fabrication is performed using a Direct Write technique. A three dimensional element is formed by depositing material on the surface, and subsequently curing the deposited material.

  • Direct Write and Additive Manufacturing Processes
    Publication number: 20100171792
    Abstract: A Direct Write method of forming components on a substrate by deposition of ink by thermally curing the ink in situ, which method overcomes the need for curing by placing the substrate in an oven. The curing is performed in an exemplary embodiment using an induction coil (6) through which an oscillating current is passed. The coil (6) is placed above the region in which Direct Write ink has been deposited. The oscillating current induces eddy currents in the ink to cause heating of the ink and thus fix the ink by curing, sintering etc.

  • Process and apparatus for monitoring surface laser cleaning
    Patent number: 6274874
    Abstract: A process and apparatus for monitoring the cleaning of a surface (1) by laser irradiation includes illuminating the surface (1) to be cleaned, being cleaned or having been cleaned by ultra-violet irradiation provided either by the cleaning laser or by a further source (5) sufficient to excite into fluorescence contaminants (10, 11) on the surface (1) which fluoresce under ultra-violet irradiation.
