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 searing 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).
1 . A brake disk, comprising: a basic body with at least one contact surface, the basic body being formed of gray cast iron; and a wearing coat applied to the at least one contact surface, wherein the at least one contact surface of the basic body is modified by laser radiation to realize the bond between the wearing coat and the basic body, and wherein the at least one contact surface of the basic body is modified by laser radiation such that the at least one contact surface is decarburized. 2 . The brake disk as claimed in claim 1 , wherein the at least one contact surface of the basis body is further modified by radiation to have one or more of a predetermined structure, a predetermined degree of cleanness, and a predetermined roughness. 3 . The brake disk as claimed in claim 2 , wherein the at least one contact surface is further modified to have the predetermined structure, and wherein the predetermined structure of the at least one contact surface is configured in one or more of a meandering form, a grooved form, and a spiraled form. 4 . The brake disk as claimed in claim 1 , wherein the wearing coat is sprayed on the at least one modified contact surface of the basic body. 5 . The brake disk as claimed in claim 2 , wherein the at least one contact surface has a modified surface topography having the predetermined roughness, the modified surface topography being caused by a combination of melt and vapor produced by melting and vaporizing portions of the at least one contact surface by the laser radiation.
