1. A method for producing a brake disk for a wheel brake of a land vehicle, the method comprising:
laser depositing a duplex steel anti-corrosion layer to an axial friction side of a main body produced from gray cast iron at a surface speed of more than 10 m/min, the laser depositing comprising continuously introducing a duplex steel powder into a laser beam and at the same time continuously introducing a carbide powder into the laser beam; and
applying an anti-abrasion layer to the anti-corrosion layer.
