Abstract: An economical resistant bearing surface reinforcement is to be provided for a reciprocating piston of an internal combustion engine, especially one using an aluminium alloy as the basic material, especially one such designed for an engine with cylinder running surface of alluminium alloy. To this end, the prior art galvanically applied steel, nickel or chromium coatings are to be replaced by a synthetic-resin-bonded graphite coating with incorporated metal particles. The metal particles may be nickel, steel, bronze, chromium, silver or alloys thereof. The running layer may also be a thin, adhesively secured metal foil. As a further alternative, the bearing layer may also be formed by metal plates secured to the piston body mechanically or by casting.

Abstract: A piston (10) containing a cavity (16) is manufactured by forming a box (20; 50; 70; 80). The interior of the box defines the cavity (16). The box is mounted in a die cavity (26) and the piston is cast around the box. The box is provided with projections (22c; 24c; 52; 58; 73) which enter recesses in the wall of the die cavity and support the box. After removing the piston from the die cavity, the projections are machined off.
