Abstract: A method for controlling a braking system of a motor vehicle that includes a plurality of wheels, at least one electric motor as a drive, a service brake and a vehicle dynamic control system. The wheels can be braked by a deceleration torque applied by the service brake and at least partially by a deceleration torque (ME) applied by the electric motor where slippage which arises as a result of braking and/or of intervention by the vehicle dynamic control system is regulated at least primarily through adjustment of the deceleration torque applied by the electric motor. When necessary, a drive torque is applied to regulate slippage or to cause a locked wheel to rotate by the electric motor.

Abstract: The disclosure relates to a mirror module, in particular for a microlithographic projection exposure apparatus, including a mirror, which has a mirror body and an optically effective surface. The mirror body has a first material, and a supporting structure for connecting the mirror body to an objective structure. The supporting structure has a second material. The first material and the second material differ in terms of their coefficients of thermal expansion by less than 0.5*10?6K?1 in a temperature range around an operating temperature which is reached by the mirror module during operation in the region of the connection of the mirror body to the supporting structure.

Abstract: A process for forming a high-strength, wear-resistant composite layer on the surface of an aluminum alloy substrate from an applied additive material. The additive material consists of an alloy or powder mixture which contains aluminum, silicon and at least 15% by weight of iron. Irradiating the alloy powder or powder mixture which has been positioned on the surface of the aluminum alloy substrate using a laser melts together with the alloy or powder mixture and a superficial part of the aluminum alloy substrate.

Abstract: The invention relates to a method for the formation of a high-strength and wear-resistant composite layer on the surface of an aluminium-alloy substrate made from an applied metal filler. Said metal filier comprises an alloy or a powder mixture containing aluminium, silicon, and at least 15 wt. % iron. The alloy or powder mixture arranged on the surface of the aluminium-alloy substrate is fused with a surface component of the aluminium-alloy substrate, by means of irradiating the alloy or powder mixture with a laser.

Abstract: A process for joining or welding components made from case-hardened steel to one another or to components made from cast iron uses a nickel-containing filler. The components are not prepared for the welding operation, i.e., the components do not undergo at least partial abrasion of surfaces to be joined.

Abstract: A capacitor foil made of aluminum or an aluminum alloy whose edge has been treated using a LASER beam exhibits practically no burrs or cracks, as a result of which an increase in the nominal field strength of capacitors made with such a foil becomes possible. A further increase in the nominal field strength is achieved by creating at least one edge with a LASER beam which is enclosed in a reactive gas or gas mixture having a concentration of oxygen greater than the concentration of oxygen in air.
