PURPOSE: A method is provided to improve he adhesion of the Ti film to the magnet body and the Al film, since the Al film formed as the intermediate layer acts as a sacrificial film of the permanent magnet body and the underlying Ti film layer, CONSTITUTION: A permanent magnet whose initial magnetic characteristics are hardly deteriorated even when the magnet is subjected to a salt spray long test and which has a stable high magnet characteristics, a stable high abrasion resistance, and a stable high corrosion resistance and a method for manufacturing the magnet. After the surface of the permanent magnet is cleaned by, e.g., an ion sputtering method, an Al film is formed on the surface of the magnet as an intermediate layer, an AlN, TiN, AlxN film is formed on the surface of the intermediate layer by a thin film forming method such as ion plating in an N2 gas and a Ti1,AlxN film is formed by a thin film forming method such as ion reaction plating in an N2 gas. |
