Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for producing a brake disk, comprising: irradiating at least one contact surface of a basic body of a brake disk with a laser to simultaneously (i) remove organic deposits from the at least one contact surface, (ii) modify a chemical composition of the at least one contact surface by decarburizing the at least one contact surface, and (iii) modify a surface topography of the basic body by increasing a roughness of the at least one contact surface, and applying a wearing coat to the at least one contact surface having the at least one modified predetermined parameter, wherein the basic body is formed of gray cast iron, and wherein the at least one contact surface is decarburized by performing the irradiation in presence of reactive gases. 2. The method for producing a brake disk as claimed in claim 1 , wherein the at least one contact surface of the basic body is one or more of heated, melted, vaporized, and cleaned by way of settable parameters of the laser radiation. 3. The method for producing a brake disk as claimed in claim 1 , wherein the laser radiation for modifying the surface topography of the at least one contact surface of the basic body is conducted in one or more of a meandering form, a grooved form, and a spiraled form in order to increase the roughness of the at least one contact surface. 4. The method for producing a brake disk as claimed in claim 1 , wherein the wearing coat is sprayed onto the at least one modified contact surface of the basic body.
