Abstract: A coating removal process includes providing a coating removal vessel having a sealable processing volume therein, providing a coating removal fluid, which reacts with the coating, at an elevated temperature above the ambient temperature surrounding the removal vessel, in the sealable processing volume, locating a component having a coating thereon to be removed in the processing volume, sealing the sealable process volume from the ambient surrounding the processing volume, heating the coating removal fluid to a temperature greater than the boiling point thereof at the pressure of the surrounding ambient, removing the coating from the component using the coating removal fluid at the temperature greater than the boiling point thereof at the pressure of the surrounding ambient, reducing the temperature of the coating removal fluid to a temperature less than the boiling point thereof at the pressure of the surrounding ambient, venting the sealable volume to the surrounding ambient, and removing the component fro

Abstract: Methods and apparatuses are disclosed for applying a twin wire arc spray composite coating to achieve surface effects on a substrate having predetermined characteristics.

Abstract: A deposing ring and cover ring for extending process components life and performance for process chambers are disclosed. A deposition ring including a protruding surface is positioned in spaced apart relation with a cover ring including a depressed surface. Indicated surfaces of the deposition ring and cover ring may be covered with a coating to improve adhesion of deposited materials.
