Abstract
A method of imparting wear-resistance to a contact face of a turbine blade Z-notch comprising applying a flexible cladding sheet comprising a Co-based cladding alloy and an organic binder to the contact face of the Z-notch, heating the turbine blade Z-notch with flexible cladding sheet thereon to volatilize the organic binder and remove it from the cladding sheet, and further heating the turbine blade Z-notch with flexible cladding sheet thereon to sinter the cladding sheet by liquid phase sintering, thereby cladding the cladding sheet to the contact face to produce a wear-resistant layer thereon.
