摘　　要：锌及镀锌层表面稀土转化膜具有良好的耐蚀性能和无毒、无污染等优点,是最有希望替代铬酸盐处理的转化膜之一,具有良好的发展前景。本文综述了国内外关于锌及镀锌层上单一稀土转化膜的成膜工艺及其机理,并概述了国内外稀土复合膜的研究成果。Having excellent corrosion resistance and nontoxic properties, rare earth conversion coatings are considered to be an attractive alternative to chromates for zinc and zinc coatings and show a considerable developing prospect. The fihn forming technology and mechanism of single rare earth conversion coating on zinc and zinc coatings at home and abroad were reviewed. The research results of rare earth composite conversion coating were summarized.
