摘要： Some die cast aluminum alloy articles have internal cylindrical surfaces such as the round internal cylinder surfaces of a cylinder block for an internal combustion engine. During casting solidification molten aluminum alloys shrink against the metallic permanent mold tools used to mold and define such internal surfaces, and tend to stick to the tool surfaces making it difficult to remove the casting. The tendency of some aluminum casting alloys to solder to the tool can further intensify sticking. In this invention, an aluminum alloy sleeve is placed on and over the tool surface before casting and the sleeve isolates the tool from the molten aluminum. The sleeve becomes bonded to the casting and facilitates removal of the casting from the tool. The sleeve may be (and preferably is) fully machined from the internal casting surface. The sleeve may be of the same composition as the casting, in which case handling and recycling of machining chips would be facilitated. The practice of the invention is also applicable to die casting of magnesium alloys using magnesium sacrificial sleeves.

摘要： A linerless engine includes a casting defining a bore having an inner surface and a central longitudinal axis. The casting is formed from a castable aluminum-silicon alloy including silicon particles present a range of from about 11 to about 12.5 parts by weight. The inner surface has a surface variation defined by at least some of the silicon particles protruding toward the axis for from about 0.6 to about 1.5 microns. The linerless engine includes a piston slideably disposed within the bore and configured for translating along the axis, wherein the piston is formed from an aluminum alloy and includes a body having a skirt portion coated with a first coating, and at least one ring encircling and in contact with the body. The ring is coated with a diamond-like coating that is free from degradation when in contact with the at least some of the silicon particles.

摘要： A major engine casting, such as an engine block or a cylinder head, fabricated of either magnesium or aluminum alloy, has a cast-in-place metal tube or form embedded within it. The tube or form enables circulation of liquid while substantially physically isolating the casting alloy from the circulating liquid and thereby restricting or eliminating corrosive interaction between them.

摘要： A valve assembly includes a tubular valve stem guide and a valve having a valve stem slidable in the bore of the valve stem guide. A lower valve stem seal has an annular body surrounding the valve stem and a skirt sealing with the valve stem guide. An upper valve stem seal has an annular body sealingly mounted on the valve stem and a skirt portion overlapping with the annular body of the lower valve stem seal during the reciprocating movement of the valve stem so that the upper and lower valve stem seals cooperate to prevent flow of oil to the bore of the valve stem guide. The valve stem is coated with a diamond-like carbon coating or a hard nitride coating, and the valve stem guide is of powered metal construction with approximately 1% by weight solid lubricant such as molybdenum disulfide or tungsten disulfide.

摘要： A process for remediating the insulating properties of magnet wire insulation is described. Magnet wire, used in electric motors and other electrical devices, comprises an electrically-conductive core covered by a thin insulating layer. The insulating layer may be damaged or compromised during manufacture or service. A process for incorporating polymerizable materials, sequestered in microcapsules, within the insulating layer is described. When the insulating layer is subjected to conditions sufficient to compromise its insulating character, the microcapsules fracture and release their contents which then polymerize and re-establish the insulating properties of the layer.
