Abstract

In the present paper, CO₂ laser coating of a cobalt base alloy on a 12% chromium steel with a view to applying it to the protection of steam turbine blades against wear was investigated in order to achieve coatings thicker than 1.5 mm and 20 mm wide and applying the process to test-blades for evaluating their abrasion/erosion resistance.
