Apparatus for producing graded-composition coatings
First Claim
1. Apparatus for depositing at least one graded composition coating on a surface of at least one substrate where the graded coating includes at least two component materials where the relative percentages of the component materials with respect to each other varies through the thickness of the coating, said apparatus comprising:
- at least two deposition sources for respectively providing said two component materials;
at least one mask having at least one aperture, said mask being disposed between at least one of said two deposition sources and said substrate; and
motion effecting means for effecting relative motion betweeen said substrate and said deposition sources where the width of the aperature varies in a direction substantially parallel to said relative motion between the substrate and the deposition sources to thus effect a predetermined variation of said relative percentages of said component materials as a function of at least the shape of the aperture in the mask such that the composition of the graded coating is uniform over the surface of the substrate.

Abstract
Apparatus for depositing a coating on at least one substrate where the coating includes at least two component materials where the relative percentages of the component materials with respect to each other varies through the thickness of the coating. The apparatus includes at least two deposition sources for respectively providing the two component materials, at least one mask having at least one aperture, the mask being disposed between at least one of said two deposition sources and the substrate, and a motion effecting mechanism for effecting relative motion between the substrate and the deposition sources to thus effect a predetermined variation of the relative percentages of the component materials as a function of at least the shape of the aperture in the mask.

26. An apparatus for depositing at least one graded composition coating on a surface of at least one substrate where the graded coating includes at least two component materials where the relative percentages of the component materials with respect to each other varies through the thickness of the coating, said apparatus comprising:
-
means for directing said two component toward said substrate; means including an aperture for intercepting a portion of at least one of said two component materials prior to said portion reaching the substrate; and means for relatively moving the substrate with respect to the component materials being deposited thereon where the width of the aperture varies in a direction substantially parallel to said relative movement of the substrate with respect to the component materials being deposited thereon to thus effect a predetermined variation of said relative percentage of said component materials as a function of at least said intercepted portion of said one component material such that the composition of the graded coating is uniform over the surface of the substrate.

27. Apparatus for depositing a coating on at least one substrate where the coating includes at least two component materials where the relative percentages of the component materials with respect to each other varies through the thickness of the coating, said apparatus comprising:
-
at least two deposition sources for respectively providing said two component materials; at least one mask having at least one aperture, said mask being disposed between at least one of said two deposition sources and said substrate; and motion effecting means for effecting relative motion between said substrate and said deposition sources where the aperture in the mask linearly varies in size in the direction of relative motion of the substrate with respect to the mask so that the amount of material deposited from said one source linearly varies through the thickness of the coating such that the composition of the graded coating is uniform over the surface of the substrate.

28. Apparatus for depositing a coating on at least one substrate where the coating includes at least two component materials where the relative percentages of the component materials with respect to each other varies through the thickness of the coating, said apparatus comprising:
-
at least two deposition sources for respectively providing said two component materials; at least one mask having at least one aperture, said mask being disposed between at least one of said two deposition sources and said substrate; and motion effecting means for effecting relative motion between said substrate and said deposition sources where the aperture in the mask non-linearly varies in size in the direction of relative motion of the substrate with respect to the mask so that the amount of material deposited from said one source non-linearly varies through the thickness of the coating such that the composition of the graded coating is uniform over the surface of the substrate.
