    Abstract: A method of making a plain bearing sliding layer for use in internal combustion engines, comprising the immersion of a metal substrate in a chemical solution containing copper, tin and lead salts to which is added one of the compounds represented by the following three exemplary structures: ##STR1## where X is one of the chemical elements selected from sulphur and nitrogen, --C represents one carbon atom, and radicals R.sub.1 and R.sub.2 represent the allowed variations, from a single hydrogen atom up to the typical structures of inorganic compounds or aliphatic, aromatic or cyclic chain organic radicals. The chemical solution is subjected to an electric current with a density and potential controlled as a function of time, thereby effecting the selective electrodeposition of the solution elements on the substrate so as to form successive and alternate layers of softer material and harder material. Each of the layers of softer metal is a Cu-Sn-Pb alloy layer and each of the layers of harder material is a pure copper or a Cu-Su alloy layer.

    Abstract: A piston (20) for an internal combustion engine includes an upper crown (22) and a lower crown (24) that are each fabricated using a same strong material, such as steel and fastened together using a plurality of fasteners (50). The piston (20) provides increased strength resulting in improved design flexibility and smaller sized engines that produce the same amount of power. Piston ring grooves (100, 102, 104) are also provided in either one or both of the upper and lower crowns (22, 24) which control piston combustion height. A deeper combustion bowl (72) is also available with the piston (20).

    Abstract: A method of manufacture of novel light-weight pistons of aluminum forgings with an integral iron insert ring by fusion welding is described. The aluminum piston forging is provided with a configuration adapted to receive the iron insert ring which may be coated to provide an inter-metallic joining alloy. The configured piston forging is placed in a mold, the ring is positioned in the configuration. The mold is rotated and molten alloy is introduced at an angle to deoxidize the forging and the ring, sweep the oxides to non-critical areas of the mold and to join the forging to the ring upon cooling to form a fusion weld.
