A drive component is disclosed. The drive component may include a base of a first material having a first hardness and a plurality of wear inserts of a second material having a second hardness greater than the first hardness. The plurality of wear inserts may extend from an interior of the base to an exterior surface of the base. The base and the plurality of wear inserts may be a composite casting.

A composition of the wear-resistant material of the present invention includes high-temperature resistant skeleton metal materials, ceramic fiber materials and ceramic particle materials with the mass ratio of (10-60):(1-30):(10-70). The high-temperature resistant skeleton metal materials are foam metal or high-temperature resistant metal fibers. The wear-resistant material is good in wear-resistance, high in tenacity, suitable for occasions with high requirements for wear-resistance and tenacity and capable of being locally attached to the surface of the light metal alloy matrix to improve the wear-resistance and tenacity of the light metal alloy matrix under high temperature conditions. The locally-reinforced light metal matrix composites of the present invention are the light metal alloy matrix locally-reinforced through the wear-resistant material. A manufacturing method of the locally-reinforced light metal matrix composites of the present invention is to metallurgically bond the wear-resistant layer with the light metal alloy matrix is through the squeeze casting technique.

A composite tooth is described for working the ground or rocks. The tooth includes a ferrous alloy having a portion reinforced at least partially by an insert. The portion reinforced by the insert is configured to allow, after in-situ reaction, the obtention of an alternating macro-microstructure of millimetric areas concentrated with micrometric globular particles of titanium carbides separated by millimetric areas substantially free of micrometric globular particles of titanium carbides. The millimetric areas concentrated with micrometric globular particles of titanium carbides form a microstructure in which the micrometric interstices between the globular particles are also filled by the ferrous alloy. The macro-microstructure generated by the insert is at least 2 mm, preferably at least 3 mm from a distal surface of the tooth.

A method for manufacturing a turbine engine vane a root connected to a blade extending in a longitudinal direction includes the steps of providing a root; and providing mold with a first cavity and a second cavity that together define a recess in which the vane is formed. The recess includes a first space in which the blade is formed and a second space in which the root (1), c) is formed. The method further includes the steps of providing aluminum strips; positioning a fibrous reinforcement; arranging the vane root in the second space; and injecting a foam comprising aluminum or injecting an aluminum alloy into the first space of the recess of the mold such that the foam impregnates the fibrous reinforcement.
