。[Prior Art] With the need for lighter vehicles and higher output engines, aluminum alloys have been increasingly used in place of iron. However, although aluminum alloys have the advantage of being lightweight, they have problems such as a lack of heat resistance, wear resistance, and rigidity. As a means of solving these problems, ceramic fiber-impregnated aluminum pistons (Japanese Patent Application Laid-Open No. 1983-93948) and nickel porous bodies (however, chemical copper plating is applied to urethane porous bodies) are available as a means to counter the lack of wear resistance of aluminum alloy pistons. Later, a composite piston (Japanese Patent Laid-Open No. 59-21259 and Japanese Patent Laid-Open No. 60-1183) using a nickel-plated urethane porous body and then burned out) was developed.
67) or cylinder block liner (
As an alternative to steel, an aluminum block (Japanese Patent Application Laid-open No. 82-28611i80) is known, which is manufactured by using cast iron fibers and aluminum to form an intermetallic compound.

むづかしいなどの問題がある。However, these conventional techniques have the disadvantage that the reinforcing materials shown in the example of pistons are high cost, and the generation of intermetallic compounds as a substitute for cylinder block liners has the drawback that the intermetallic compounds are hard and brittle, which causes processing problems. In addition, there are other problems, such as the difficulty of setting conditions to form a certain thin film of intermetallic compounds.
