    摘要： A method of bonding a metal to a substrate involves forming an oxide layer on a surface of the substrate, and in a molten state, over-casting the metal on the substrate surface. The over-casting drives a reaction at an interface between the over-cast metal and the oxide layer to form another oxide. The other oxide binds the metal to the substrate surface upon solidification of the over-cast metal.

    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： 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 magnesium alloy comprising up to about six weight percent zinc and up to about one weight percent cerium may be hot worked to produce an intermediate or final alloy workpiece that exhibits enhanced ductility and strength at room temperature. The addition of zinc and a small amount of cerium may affect the magnesium alloy by increasing strength and ductility, and improving the work hardening behavior.
