Abstract

Metallic product coated with a matrix of Co/Cr-alloy with a dispersed hard phase consisting of Cr3C2. Preferably the Co/Cr matrix comprises 60 to 96% of Co and 40 to 4% of Cr while the coating comprises 40% ≤ Co < 70%, 25% ≤ Cr < 50%. The Cr3C2 content is comprised between 30 and 60%. <??>According to a preferred embodiment of the invention, the Co/Cr matrix represents 45 to 70 wt% of the coating, preferably 55 to 70wt% and the Cr3C2 represents the 30-55wt%, preferably the 30-45wt%. <IMAGE>
