20110111132 | SYSTEM AND METHOD FOR DEPOSITING COATINGS ON INNER SURFACE OF TUBULAR STRUCTURE - A system and method for depositing coatings on an inner surface of a tubular structure includes at least one pump for creating and maintaining a vacuum in the tubular structure, a meshed electrode adapted to be positioned in a center of the tubular structure, and a biased voltage power supply connected to the meshed electrode. The biased voltage power supply is adapted to apply a negative voltage to the meshed electrode such that the negative voltage causes a hollow cathode discharge inside the meshed electrode. The creation of the hollow cathode discharge causes ions to be drawn out of a mesh on the meshed electrode and accelerate onto an inner surface of the tubular structure, thereby coating the inner surface with a desired coating. | 05-12-2011 |
20110111190 | Method For Applying A Diffusion Barrier Interlayer For High Temperature Components - A coated substrate and a method of forming a diffusion barrier coating system between a substrate and a MCrAl coating, including a diffusion barrier coating deposited onto at least a portion of a substrate surface, wherein the diffusion barrier coating comprises a nitride, oxide or carbide of one or more transition metals and/or metalloids and a MCrAl coating, wherein M includes a transition metal or a metalloid, deposited on at least a portion of the diffusion barrier coating, wherein the diffusion barrier coating restricts the inward diffusion of aluminum of the MCrAl coating into the substrate. | 05-12-2011 |
20110256417 | Oxidation Resistant Nanocrystalline MCrAl(Y) Coatings And Methods of Forming Such Coatings - The present disclosure relates to an oxidation resistant nanocrystalline coating and a method of forming an oxidation resistant nanocrystalline coating. An oxidation resistant coating comprising an MCrAl(Y) alloy may be deposited on a substrate, wherein M, includes iron, nickel, cobalt, or combinations thereof present greater than 50 wt % of the MCrAl(Y) alloy, chromium is present in the range of 15 wt % to 30 wt % of the MCrAl(Y) alloy, aluminum is present in the range of 6 wt % to 12 wt % of the MCrAl(Y) alloy and yttrium, is optionally present in the range of 0.1 wt % to 0.5 wt % of the MCrAl(Y) alloy. In addition, the coating may exhibit a grain size of 200 nm or less as deposited. | 10-20-2011 |
