Abstract
A manufacturing method provides a nuclear reactor component comprising a substrate and a coating covering a surface of the substrate. The manufacturing method comprises laser-marking a pattern on the surface of the substrate, the marking being carried out so as to form recessed reliefs outlining the pattern in the surface of the substrate, and then applying the coating to the surface of the substrate over the pattern.
Claims19
A method for manufacturing a nuclear reactor component comprising a substrate and a coating covering a surface of the substrate, the manufacturing method comprising:
- laser-marking a pattern on the surface of the substrate, the laser-marking being carried out so as to form recessed reliefs drawing the pattern into the surface of the substrate;
- and then
- applying the coating to the surface of the substrate over the pattern, the coating being made of a pure chromium material comprising, by weight, at least 99% of chromium or a chromium-based alloy comprising, by weight, at least 85% of chromium,
- a depth of the recessed reliefs being less than a thickness of the coating.
