ABSTRACT:
Spherulitic cast iron container bodies for radiation shielding containers for irradiated fuel elements are provided with sealing coatings which prevent the body from acting as a galvanic element in a water basin during the filling of the container with the irradiated fuel elements. The coating of nickel, nickel based alloys or chromium
ickel austenitic alloys is applied by applying particles of a diameter less than the diameters of open pores of the body surfaces to these surfaces and then fusing the particles together and to the substrate with a laser beam, preferably in a back and forth motion. The pores are thus filled with the particle melt layer.
