Abstract
A titanium based alloy compressor blade is given a wear-resistant portion such as a tip portion by producing an interfitting male/female joint between the blade and the wear-resistant portion in which the joint portion of the latter is produced with inwardly directed corrugations and the former is pressed at elevated temperature after assembly of the two parts so as to cause the material of the blade to flow into and conform to the shape of the latter and to produce a diffusion bond between the two parts. Interlayers may be used to improve chemical compatibility between the respective parts.
