Abstract: An improved aluminum-silicon-copper alloy having a relatively high level of bismuth is provided which is particularly wear-resistant and sufficiently self-lubricating so as to be suitable for use in a wearing component even when poorly lubricated. The relatively high bismuth level within the alloy cooperates with the other elemental additions so as to provide a sufficiently low friction bearing surface (or self-lubricity), which significantly enhances the wear resistant properties of the alloy. In particular, the preferred aluminum alloy is suited for use in a socket plate which receives high strength steel bearing members within a compressor unit of an automobile air conditioning system. The improved aluminum alloy should minimize wear and alleviate galling of the socket plate during use. In addition, the improved aluminum alloy should have sufficient strength and ductility so as to permit swaging of the socket plate formed from the alloy around a balled end of the high strength steel bearing member.

Abstract: Disclosed is a method of floatingly supporting a metallic strip in a direct firing type continuous heat treating furnace accommodating a plurality of floater nozzles. In this method, furnace gas is initially supplied to and pressurized by a plurality of multistage booster fans. The temperature of the furnace gas to be supplied to the booster fans is less than a critical temperature of the fans. When the temperature of the furnace gas is less than the temperature of the material of the strip, the temperature of the furnace gas is raised to a temperature near the material temperature in combustion chambers provided with respective direct firing type burners. The furnace gas is then supplied to the floater nozzles, the internal pressure of which is controlled prior to being jetted.

Abstract: The surface of a metal workpiece is remelted by a heat producing energy beam so as to form a molten metal layer thereon. While remelting the surface, a magnetic field is generated coaxially with the energy beam and is applied across the molten metal layer so as to cause the heat energy to flare and, thereby, produce a Lorentz force in the molten metal layer. By the Lorentz force, the molten metal is agitated. The heat energy and magnetic field are oscillated, or reciprocally moved, relative to the surface so as to cause a flow of the molten metal from the edges of the molten metal layer toward the center, thereby providing a uniform chilled layer thickness.
