Abstract
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.
Claims5
A coating system comprising:
- a mask positioned adjacent to a first portion of a part to be coated, wherein said mask is configured to be cyclically moved from said first portion of said part;
- and
- means for moving said mask relative to the part, wherein said moving means comprises a gear mechanism, said gear mechanism includes one gear that is configured to be counter rotational configured to move said mask back and forth;
- wherein said first portion (16) is a leading edge of an airfoil portion of said part and said gear mechanism is configured to move 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.
