Abstract

A friction brake body, in particular a brake disc, for a friction brake of a motor vehicle is disclosed. The friction brake body has a main part with at least one wear protection layer on at least one frictional contact region of the main part. The wear protection layer forms a frictional contact surface on the wear protection layer face facing away from the main part. The degree of hardness of the wear protection layer increases incrementally or continuously from the main part to the frictional contact surface.
