Abstract

PURPOSE:To improve the erosion resistance on the front end face of a blade by machining a material consisting of the matrix of an aluminum base material and fiber reinforced metal to a blade shape. CONSTITUTION:A preform 2 of reinforcing fibers such as ceramic whiskers or short fibers is partially disposed in a casting mold 1. The melt 3 of aluminum or aluminum alloy is poured into the casting mold 1 and an ingot 5 is formed. The aluminum is, therefore, impregnated in the form of the matrix into the preform 2. The ingot 5 is then finished by machining to the shape of the blade 4. Since the fiber reinforced metal is disposed at the front end face 4a, the erosion resistance characteristic is improved and the life is extended.

Conventional blades made of aluminum or aluminum alloys often suffer from erosion at the end of the blade due to dust and droplets contained in the fluid. In addition, measures have been taken to prevent such erosion by lining or coating the blade surface with rubber or hard organic resin, but even if these 7 erosion prevention measures are taken, the lining material and coating film will still be damaged. It was difficult to maintain satisfactory erosion resistance because it often peeled off easily.
