  • Restoration process for porosity defects in metal cast products
    Patent number: 8220124
    Abstract: A restoration process for restoring surface porosity defects on a component surface. The areas of a component surface having surface porosity defects are identified for restoration. The restoration surface is subsequently sprayed with a restoration spray to restore the surface porosity defects. The component surface is then finished to create a final component substantially free of surface porosity.
    Type: Grant

  • Restoration process for porosity defects in metal cast products
    Patent number: 7712216
    Abstract: A restoration process for restoring surface porosity defects resulting from the casting process in metal cast products. The areas of a cast product having surface porosity defects are identified and the areas not containing surface porosity defects are masked using an adhesive, reusable, rubberized mask. The masked surface is subsequently cleaned and a metal spray is applied to the surface porosity defects. The mask is removed and the restored surface porosity defects are hand finished to create a cast product having less than 0.05% surface porosity.

  • Restoration process for porosity defects in high pressure die cast engine blocks
    Patent number: 7188416
    Abstract: A restoration process for restoring surface porosity defects in engine blocks cast using a high pressure die cast method. The areas of an engine block having surface porosity defects are identified and the areas not containing surface porosity defects are masked using an adhesive, reusable, rubberized mask. The masked surface is subsequently cleaned and a metal spray is applied to the surface porosity defects. The mask is removed and the restored surface porosity defects are hand finished to create an engine block having less than 0.05% surface porosity.
