A method for forming an electrical contact is provided. The method includes grinding a silicon carbide surface using a grinding disk which includes a grinding face containing nickel or a nickel compound, such that particles of the nickel or nickel compound from the grinding disk are embedded in the ground silicon carbide surface, and hardening the ground silicon carbide surface with the aid of a laser, such that at least some of the embedded nickel particles form a nickel silicide with silicon from the silicon carbide.
