可用于NdFeB永磁体表面保护的锌铝膜涂层技术

DACROMET──a New Protection for NdFeB Magnets

介绍了一种可用于NdFeB永磁体表面保护的涂层技术──DACROMET（达可乐－锌铝膜），该技术最突出的优点是无环境污染，耐蚀性、耐氢脆优异。初步实验证明，锌铝膜用于粘结NdFeB永磁体效果较好，用于烧结NdFeB永磁体很好，优于电镀锌和电镀镍．

A new protection coating for NdFB magnets-DACROMET (Zn - Al coating),which has the advantages of no-environmantal pollution, hydrogen brittleness and corrosion-resistanceis introduced. The experiment asults show that DACROMET gains an advantage overZn-electroplation or Ni-electroplatoing for NdFeB magnets.
