Coating Toughness Estimation through a Laser Shock Testing in Ni-Cr-B-Si-C Coatings

Abstract:

In the nuclear field, efforts are made to find substitutes to cobalt hardfacing alloys since these alloys have a principal drawback, the transmutation from stable ⁵⁹Co to ⁶⁰Co under neutron irradiation. In case of wear, fragments could be deposed on the surface of primary circuit and thus contaminate it, causing a real issue for deconstruction.
