Abstract
The effect of long-term hydrogenation of the (Sm,Dy,Gd)Co-5 permanent magne t on mechanical degradation and decay of magnetic properties in service is investigated. The application of greater than or equal to 15 mu m Cd-coatin gs is recommended to prevent the hydrogenation of the permanent magnet. (C) 1998 Elsevier Science Ltd. All rights reserved.
