Abstract
According to the inventive method for producing a composite part (4), a support body (1) is produced from a powder with a ferrous alloy base using powder metallurgy. A magnet body (2) which is based on an alloy that is rich in rare earths is applied to the support body (1) and both are then sintered in a furnace (1), whereby a solid joint is formed between the support body (1) and the magnet body (2).
Claims13
A process for the production of composite parts, in which a magnet body made of an alloy rich in rare earths is bonded along a boundary surface with a soft-magnetic support body, comprising:
- a) molding the support body and the magnet body from powder;
- b) forming a molten phase in the region of the boundary surface by a heat treatment, which penetrates into the support body during the heat treatment.
