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： The corrosion resistance of formed and shaped sheet magnesium alloy articles may be improved by applying to the article a substantially crack-and pore-free ductile metal layer on at least selected surfaces and cut or sheared edges. An exemplary ductile metal may be aluminum or its alloys. Two methods of applying such a ductile metal layer are described. One method is suitable for extended areas of the magnesium alloy sheet surface, and is applied prior to stamping the article, while a second method, suitable for cut or sheared edges, is intended for application after the article is fully formed. The incorporation of both methods into conventional sheet metal stamping processes to form the corrosion resistant formed magnesium article is described.

摘要： A system may be used to detect corrosion between a first metal and a second metal, where the second metal is positioned adjacent to the first metal. The system may include a processor electrically coupled to each of the first and the second metals and configured to monitor a complex impedance between the first metal and the second metal, where the complex impedance may include a real component and an imaginary component. The processor may compare the real component of the complex impedance to a first threshold, compare the imaginary component of the complex impedance to a second threshold, and indicate a likelihood of corrosion if at least one of the real and imaginary components are below their respective threshold.

摘要： A clinching method includes establishing a first layer on a second layer. The first layer has an aperture formed therein and is thinner than the second layer. A rotating punch is engaged with the second layer through the aperture in the first layer, thereby generating frictional heat and softening the second layer. The rotating punch is configured with at least a first diameter, a shoulder, and a second diameter that is larger than the first diameter. The rotating punch is pressed into the softened second layer, thereby causing at least some of the second layer to: back extrude through an annulus defined by the aperture in the first layer and at least one of the diameters of the punch; contact the shoulder of the rotating punch; and extend onto a surface of the first layer adjacent the aperture.

摘要： A method of clinching includes contacting a punch to stacked workpieces and rotating the punch to generate frictional heat in the workpieces, and advancing the punch into the workpieces to form a mechanically-interlocking joint. Rotation of the punch may be stopped prior to advancing the punch into the stacked workpieces. The first workpiece may be formed from a first material and the second workpiece formed from a different, second material. One of the first and second materials may be magnesium or a magnesium alloy. The mechanically-interlocking joint is characterized by the absence of intermetallic compounds, and may be substantially hermetically sealed against passage of fluids and gasses. A hole may be formed in one of the workpieces and, prior to contacting the punch to the workpieces, the hole aligned substantially coaxially with the punch. Forming the mechanically-interlocking joint may include deforming both the first and second workpieces.
