摘要： A vehicle component, such as a wheel, is formed of a magnesium alloy for weight reduction in an automotive vehicle. It is expected that the wheel will be attached to other vehicle wheel-related componenets that are formed of metal compositions (for example, steel or cast iron components) that may lead to the corrosion of the magnesium wheel. Such attachment surfaces of the magnesium wheel are oxidized to form an integral and durable oxide layer on the magnesium wheel. When the magnesium wheel is attached to vehicle wheel supporting components of other alloys, the oxide layer-coated surfaces of the magnesium wheel are electrochemically isolated from the non-magnesium materials to prevent oxidation of the wheel or attached components.

摘要： A magnetic bumper apparatus for constraining a vehicle closure to a vehicle closure interface includes first and second magnetic members configured for attachment to the closure and closure interface, and a non-magnetic bumper element interposed therebetween. Each magnetic member defines a plurality of spatially modulated magnetic fields (SMMF) in corresponding patterns to provide a cumulative SMMF attractive force and a cumulative SMMF repulsive force between the magnetic members and define a separation reference and an alignment reference. The magnetic members in magnetic proximity to each other constrain the closure to the closure interface with respect to the alignment and separation references to prevent contact between a closure surface and a closure interface surface and to define at least one alignment parameter therebetween. Constraining the closure to the closure interface may include resisting a non-magnetic force inputted to the vehicle to prevent contact between the closure and closure interface surfaces.

摘要： A method of forming a casting includes providing a preform to a mold cavity. The preform is formed from one of a first metal and a second metal and defines an interface surface. A molten portion of the other of the first metal and the second metal is cast into the mold such that the molten portion proximately contacts the interface surface of the preform. An interface layer at the interface surface, a first portion defined by the mold cavity and the interface layer, and a second portion defined by the interface layer, are formed during casting. The interface layer may define a metallurgical bond between the first portion and the second portion. In the non-limiting example provided herein, the first portion is substantially comprised of aluminum and the second portion is substantially comprised of magnesium. In a non-limiting example, the casting may be configured as a vehicle wheel.

摘要： The hot stretch forming of sheet metal alloys, such as highly deformable aluminum alloy materials, is improved by using a lubricant comprising bismuth between the forming tool and the engaged surface of the sheet metal. A precursor of bismuth, such as bismuth subsalicylate, may be dispersed in a liquid and applied to the sheet metal before the sheet is heated to its forming temperature. Other lubricants such as boron nitride may be combined with the bismuth precursor. The precursor compound is decomposed to bismuth (or bismuth and carbon in the case of bismuth subsalicylate) which lubricates contact between the surface(s) of the sheet and the forming tool during forming and removal of the formed part from the tool.

摘要： The present invention relates to a heating and forming apparatus for sheet material and method for rapid heating and shaping of sheet material. The apparatus comprises a first and second respectively movable forming dies, with the first forming die having a forming surface and defining a cavity with the second forming die. The apparatus is adaptable to receive a sheet material positionable within the cavity. A heating mechanism is placed within the cavity to heat the sheet material. The forming surface of the first forming die is not substantially heated. A pressurization mechanism is in communication with the cavity to move the sheet material into conformity with the forming surface of the first die. An improvement in the process of stretch forming a sheet material into a product by using quick plastic forming (QPF) or superplastic forming (SPF) is provided.
