A friction clutch or friction brake is provided having a basic body and a friction body portion. The friction body portion can be mass-produced separately from the basic body, using a planar metal sheet-like material which is treated leading to a sintered powder friction facing. The friction clutch has a non-planar friction surface, operating in a box filled with oil as a lubricant. The friction body is applied to the basis body by form-locking friction, friction-gripping and/or material-locking techiques. In a preferred embodiment, the friction clutch or brake is a synchronizing ring and/or a correcting ring for motor vehicle shift gears. The friction clutch or friction brake according to the invention has particularly favorable friction properties, a long service life and low manufacturing costs. In a great number of applications, the shaping of separte draining grooves for expelling the oil when the friction grip is produced between matching components can be omitted.
