Protection piece for the leading edge of a blade

摘要

The piece has an inner layer (5) and an outer layer (7) that is made of an aluminum alloy reinforced by silicon carbide particles. The proportion of particles in the alloy varies from 15 to 40 percent by weight. The inner layer is made of the aluminum alloy reinforced/not reinforced by the silicon carbide particles. The proportion of particles inside the layers increases from the layer (5) to the layer (7). An independent claim is also included for an assembly comprising a leading edge of a blade and a protecting piece.
