Abstract : The patent describes a process for applying erosion resistant coverings to surfaces of structures exposed to cavitation comprising the following steps: Pretreating a surface of the covering material which is in the form of a thin sheet, to improve its adhering properties; pretreating the surface of the material to be protected (substrate) to improve its adhering properties; heating the surface of the substrate; coating said cleaned surfaces with an adhesive of the epoxy-resin-type; applying the coated surface of the covering to the coated surface of the substrate; and maintaining, preferably by evacuation, close contact between the covering, adhesive and substrate while the adhesive cures.
