Cobalt-based alloy for the coating of elements subject to erosion by liquids comprises 28-32 wt.% chromium, 5-7 wt.% tungsten, 0.1-2 wt.% silicon, 1.2-1.7 wt.% carbon, 0.5-3 wt.% nickel, 0.01-1 wt.% iron, 0.01-1 wt.% manganese, 0.2-1 wt.% molybdenum, and balance cobalt. An independent claim is also included for a method for the treatment or elements subject to erosion by liquids, which comprises the application of a cobalt-based alloy on the surface of the elements to form a layer of anti-erosion coating. |
