ABSTRACT:
A method of embedding an oxidation resistant abrasive material in the tip of a turbine blade is taught. The oxidation resistant abrasive may be aluminum oxide. Its low density is increased by coating fine particles with platinum metal to achieve a density greater than that of the metal of the blade tip. The blade tip is then melted locally to provide a pool of melt into which the high density aluminum oxide can be inserted. Freezing the melt embeds the aluminum oxide in the blade tip.
