  • Process for salvaging turbocharger compressor housings
    Patent number: 9463533
    Abstract: A method of salvaging a used, damaged turbocharger compressor housing involving the steps of machining the damaged interior surface of the housing, grit blasting the machined surface, building up the machined surface with coating material, and final machining the interior surface to its original specifications. The method includes holding the compressor housing by key datums during the machining steps.
    Type: Grant

  • Method of coating and induction heating a component
    Patent number: 8137761
    Abstract: A method of coating a component is disclosed. The method includes applying a coating composition to a surface of the component. The method also includes providing an induction coil having a coil configuration corresponding to the surface. The method further includes relatively positioning the surface and the induction coil with a gap sufficient to enable induction heating of the surface by the induction coil. Furthermore, the method includes heating the component with the induction coil sufficient to produce a coating having an empirical formula FexMnyOz, where x varies from about 0 to about 2, y varies from about 1 to about 4, and z varies from about 2 to about 8.
