Abstract
Official abstract text for this publication.
A coating system for coating a part ( 10 ), such as a turbine blade or vane, has a mask ( 14 ) positioned adjacent to a first portion ( 16 ) of the part ( 10 ) to be coated and a mechanism ( 30 ) for moving the mask ( 14 ) relative to the part ( 10 ). The mechanism ( 30 ) may be a gear mechanism or a magnetic mechanism.
First claim
Opening claim text (preview).
1 - 16 . (canceled) 17 . A coating process comprising the steps of: positioning a part within a coating chamber; positioning a mask adjacent to a first portion of said part; creating a coating vapor within said coating chamber; periodically moving said mask relative to said first portion of said part during the coating process by use of a gear mechanism, said gear mechanism includes one gear that is configured to be counter rotational and configured to move said mask back and forth; wherein said first portion is a leading edge of an airfoil portion of said part; and moving said mask from a position adjacent said leading edge to a position adjacent a suction side of said airfoil portion between 5 to 20 rotations of the part about a longitudinal axis thereof. 18 . The coating process of claim 17 , wherein said moving step comprises moving said mask away from said leading edge a distance as slight as a width of said mask. 19 . The coating process of claim 17 , further comprising rotating said mask and said part at different speeds.
