Abstract:
1. A method for repairing a damaged titanium surface of a landing gear part comprising: masking an undamaged titanium surface leaving the damaged titanium surface of the landing gear part exposed, wherein the damaged titanium surface having a depth in the orthogonal direction from the undamaged titanium surface; applying a base coat of nickel via brush coating electroplating process to the damaged titanium surface to form a prepared damaged surface, wherein the undamaged titanium surface is used as a cathode during the brush coating electroplating process and the base coat comprising a thickness of approximately 0.0005 inches; applying a nickel first coating to the prepared damaged surface to form a partially repaired surface; and applying a second coating via an electroless process to the partially repaired surface to form a repaired surface, wherein the landing gear part comprises a titanium alloy having a composition, in weight percent, of about 6 percent aluminum, about 2 percent tin, about 2 percent zirconium, about 2 percent molybdenum, about 2 percent chromium, about 0.25 percent silicon, and the remainder titanium, and wherein a total thickness of the base coat of nickel, the nickel first coating and the second coating is equal to a thickness of the depth in the orthogonal direction from the undamaged titanium surface.
