Abstract

The invention relates to a process for producing a brake disk for a vehicle, in which a friction layer is arranged at least in certain regions on a base body of the brake disk.

First claim

What is claimed:

1. A process for producing a brake disk for a vehicle, in which a friction layer is arranged at least in certain regions on a base body of the brake disk, said process comprising at least the following steps:
pre-machining the base body at least in certain regions;
heating the base body;
dipping the heated base body in a melt comprising base metal alloys, such that a functional layer is formed between the base body and a friction layer still to be applied, and
applying the friction layer at least in certain regions by use of thermal spraying processes.

2. The process as claimed in claim 1 , wherein the entire base body is dipped in the melt such that the entire base body is covered completely with the functional layer.

3. The process as claimed in claim 1 , wherein the base body is heated to a temperature of between 500° C. and 700° C. in a protective gas atmosphere.

4. The process as claimed in claim 1 , wherein, in a further step after the base body has been dipped in the melt, at least a brake rim thereof is machined to dimension, it being possible for the functional layer to have a thickness of 200 μm after finishing.

5. The process as claimed in claim 1 , wherein the melt comprises aluminum and/or zinc alloys.

6. The process as claimed in claim 1 , wherein the friction layer is applied by use of high-temperature flame spraying.

7. The process as claimed in claim 1 , wherein the friction layer is produced by use of the application of hard material powders, the friction layer having a thickness of 30 μm to 50 μm.

8. The process as claimed in claim 1 , wherein particles protrude at least partially from the friction layer and/or wherein the friction layer has incorporated particles, the diameter of which is greater than the thickness of the friction layer, such that the particles protrude from the friction layer.
