  • Diffusion coating applied by magnetron sputtering
    Patent number: 6365011
    Abstract: A method of applying diffusion coatings by magnetron sputtering includes the use of a solenoid coil which produces an alternating magnetic field to inductively heat the article to be coated. The coating may preferably be a multi-layer or multi-component diffusion coating which may include a diffusion barrier and/or a thermal barrier.

  • Magnetron sputtering method and apparatus
    Patent number: 6193853
    Abstract: An elongate emitter is used as a cathode to coat material onto a cylindrical workpiece by magnetron sputterinig. Where the inside surface of the workpiece is coated, the workpiece itself is used as the vacuum sputtering chamber. The overlap between the plasma field and the magnetic field creates a coating zone which is moved along the length of the workpiece to evenly coat the workpicce.
