Abstract
Disclosed is a method for repairing defects in kinetically sprayed surfaces. The typical defects comprise isolated or connected conical shaped holes in the kinetic spray coating. The repair involves thermally spraying a molten material into the defective area to fill in the cone followed by continued kinetic spraying to complete the coating.
