摘要：

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 acetic acid salt spray were investigated. It was found that the tested RETiCo(11) magnets were much more corrosion resistant than the alternative 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.
