Abstract (en)
[origin: CA2684972A1] Disclosed is a method for producing an abradable coating for a part of a turbo-machine. Said method comprises the following steps: a) a powdery mater ial is pretreated; b) a processable preliminary product is produced which is to be applied to a part that is to be coated; c) the preliminary product is applied to the part that is to be coated; d) a synthetic binder contained i n the preliminary product is burned off; e) the part is sintered; f) the par t is finished. Said improved method for producing an abradable coating for a turbo-machine eliminates the drawbacks of the solutions known from prior ar t. In particular, said method is inexpensive, can be easily combined with ot her production process steps, e.g. thermal treatments that have to be carrie d out anyway, and is also suitable as a method for repairs.
