Abstract
The corrosion behaviour of six RETiCo(11) permanent magnet compounds ( RE=Y, Pr, Nd, Sm, Gd or Dy) in sulphate solutions with pH=0-4 and in a cetic acid salt spray were investigated. It was found that the tested RETiCo(11) magnets were much more corrosion resistant than the alterna tive Nd-Fe-B and Sm-Co material. The kind of RE element in the magnet composition has practically no influence on the corrosion rates in the tested environments.
