Method of repairing a metallic surface wetted by a radioactive fluid |
摘要 |
The wetted surface of a pressure vessel, a structural internal or a weld is repaired by removing the contacting radioactive fluid, forming a powder mixture of metallic particles and ceramic particles and then spraying the powder mixture on the formerly wetted surface to form a protective cold sprayed coating thereon. As-deposited coatings having a surface smoothness of 125 RMS or better may be nondestructively examined by ultrasonic, eddy current or dye penetrant tests without a preliminary grinding step.
