METHOD FOR PRODUCING AN ABRADABLE COATING ON A TURBOMACHINE

摘要

In a method for producing an inlet coating (21) on a surface of a turbomachine (10), an electric arc (37) is produced between a first electrode (31) having a first material and a second electrode (32) having a second material. A gas stream (42) is produced through the electric arc (37) onto the surface, which entrains the first material and the second material from the electric arc (37) and deposits them on the surface to form the inlet coating (21) or a precursor layer (22) of the inlet coating (21).
