Abstract: A cylinder head for an internal combustion engine, having an iron lower base part with inlet and exhaust ports and controlling valves therefor and an aluminum upper support for the camshaft and valve tappets. The upper part includes an open lattice work formed by spaced interconnected segments and curved sections extending between spaced bulkheads integral therewith that can be readily fastened to the base part to provide overhead support for the valve tappets. The lattice work has special expansion and contraction joints that connect into the bulkheads which mount the camshaft so that different rates of thermal expansion and contraction occurring between the lattice work and lower base part will cause deflection of the expansion joint and will not adversely effect the operation of the camshaft or the tappets carried by the bulkheads and lattice work.

Abstract: A surface hardened aluminum part having excellent heat resistance and abrasion resistance obtained by forming, on the surface of an aluminum base material, an alloy layer that has a uniform composition and uniform hardness, being free from cracks. An aluminum alloy powder made of aluminum and metals each of which forms an intermetallic compound of high hardness with aluminum is prepared. This aluminum alloy powder is supplied onto the aluminum base material and the aluminum or aluminum alloy contained in the aluminum base material is alloyed with the aluminum alloy powder using a high-density energy heat source to form an alloy layer. The alloy layer thus formed has an intermetallic compound of high hardness uniformly distributed throughout the layer so that the hardness of the alloy layer is uniform and cracking is unlikely to occur.

Abstract: Fastening devices such as washers, seals and drive pins subject to corrosive deterioration of all or select portions thereof wherein all or such select portions are protected from such corrosion and failure by a thin coating or coatings of hard surface material or materials. In a preferred form, the fastening device is coated with a synthetic diamond material formed as a thin layer in situ thereon. In addition to preventing moisture and other corrosive material from penetrating to the base metal, such synthetic diamond material serves to preserve the surface integrity of the fastening device preventing the formation or spread of surface flaws produced during use or during the fabrication of the fastening device.

Abstract: A piston, e.g. for an internal combustion engine, comprises a crown (16) and a skirt (12). The skirt (12) has an aperture (22) in which an insert (14) of a different material from the remainder of the skirt is secured. The insert (14) may be of plastics material injection moulded into a metal skirt. The insert (14) provides a plurality of pads (34) which extend from a thrust surface of the skirt so that the pads can transmit lateral forces and cause lubricant to be forced over the pads by hydrodynamic action during reciprocation of the piston.

Abstract: A low-friction piston construction for use in an oil-fed cylinder bore with the piston skirt relieved to define lands that are coated with SFL (graphite, MoS.sub.2, BN, and a special expoxy resin). A method of making such piston construction including provision of asperities on the skirt wall onto which the SFL coating is thermally sprayed and formation of small pockets at the mouth of the asperities to additionally act as oil replenishing reservoirs. A method of using such piston construction in an engine which comprises provisions of a slightly increased gap between the piston and cylinder wall and formation of a transferred SFL coating from the piston to the cylinder wall resulting in two polished microsmooth mating coatings, each attractive to oil films.
