Abstract:
In a molded body made of a thermoplastic molding compound, which comprises a metal powder having a mean particle diameter in the range from 0.01 to 100 mm, the metal powder is accumulated on at least one surface of the molded body such that a concentration gradient of the metal powder is present in the molding compound from the surface thereof perpendicular to the inside of the molding compound, preferably in a decreasing manner.
