A sliding bearing element has a steel supporting layer onto which a 2-layer composite is applied which consists of an aluminum-based substrate having a layer thickness hs of 0.2 to 0.4 mm and an aluminum-based sliding layer having a layer thickness hG of 0.005 to 0.1 mm. The substrate and the sliding layer are joined by roll bonding. A sliding bearing is made from two sliding bearing elements of this kind, which are predominately used for applications in high-performance engines, principally for connecting-rod bearings, crankshaft main bearings and connecting rod bushes, but also in applications in mounting camshafts and counterbalance shafts as well as transmissions.

The invention relates to a method for producing a strand from a monotectic alloy which is made of multiple constituents and in which drops of a primary phase are distributed in a uniform manner in a crystalline matrix in the solidified state. The uniform distribution can be achieved during the production process using the following method steps: a) melting the alloy constituents which consist of at least one matrix component and components that form the primary phase and heating the constituents to a temperature at which a single homogeneous phase exists; b) transporting the melt (2) in the form of strands in a transport direction which is inclined towards the horizontal at a transport speed; c) cooling the melt (2) while transporting the strand lower face perpendicularly to the transport direction in order to form a crystallization front when transporting in a cooling zone; d) setting the cooling intensity, the inclination of the transport direction, and the transport speed such that a horizontal crystallization front is formed and the Marangoni force produced by cooling and forming the primary phase in the form of drops is oriented anti-parallel to the gravitational force such that the drops of the primary phase in the matrix component move in the direction of the gravitational force; and e) drawing the alloy which has been solidified into the strand (9) out of the cooling zone.

Disclosed is a process for coating a component of a TiAl alloy in order to improve the high-temperature resistance of the component. The process comprises depositing a Pt- and Cr-free protective layer alloy comprising Ti, Al, Nb, Mo and B and optionally one or more of W, Si, C, Zr, Y, Hf, Er and Gd on the component by physical vapor deposition at a temperature of less than or equal to 600 C. The protective layer alloy has a higher Al content than the TiAl alloy of the component. A coated component made by this process is also disclosed.

Alloys comprised of a refined microstructure, ultrafine or nano scaled, that when reacted with water or any liquid containing water will spontaneously and rapidly produce hydrogen at ambient or elevated temperature are described. These metals, termed here as aluminum based nanogalvanic alloys will have applications that include but are not limited to energy generation on demand. The alloys may be composed of primarily aluminum and other metals e.g. tin bismuth, indium, gallium, lead, etc. and/or carbon, and mixtures and alloys thereof. The alloys may be processed by ball milling for the purpose of synthesizing powder feed stocks, in which each powder particle will have the above mentioned characteristics. These powders can be used in their inherent form or consolidated using commercially available techniques for the purpose of manufacturing useful functional components.
