The disclosure relates to a friction brake body for a friction brake of a motor vehicle, in particular a brake disc, wherein the friction brake body comprises a base body made from gray cast iron, and at least one wear resistant layer formed at least in areas on the base body. The wear resistant layer is a laser alloyed or laser dispersed edge layer of the base body and comprises at least one additive.

Friction brake body for a friction brake of a motor vehicle, method for producing a friction brake

A device for projecting a laser beam onto a workpiece includes at least one first optical element, at least one second optical element, and at least one third optical element. The at least one first optical element is configured to project the laser beam onto the at least one second, in particular diffractive, optical element. The at least one second optical element is configured to convert an intensity profile of the laser beam. The at least one third optical element is configured to project the laser beam onto the workpiece. The device is configured such that a diameter of the laser beam on the workpiece can be varied while maintaining the intensity profile with a stationary workpiece.

Device and method for laser material processing

A brake disc includes a basic body with at least one contact surface that has a wearing coat applied thereon. The at least one contact surface of the basic body is pretreated to realize the bond between the wearing coat and the basic body. The at least one pretreated contact surface of the basic body has a surface topography that is modified by laser irradiation and has at least one predetermined parameter. A method produces the brake disc.
