Title:
RARE-EARTH BONDED MAGNET AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2003234228
Kind Code:
A
Abstract:
To provide a rare-earth bonded magnet that is excellent in corrosion resistance, and to provide a method of manufacturing the magnet.
This rare-earth bonded magnet manufactured by kneading the powder of a rare-earth alloy with a resin and molding the kneaded product has a coating film composed of a triazine dithiol compound on its surface and a plated oxidation-resistant layer on the coating film. The coating film formed on the surface of the magnet is formed by performing the electrolysis of a triazine-based compound solution containing a mercapto group.
