摘　　要：采用气体低温稀土多元共渗方法,研究了S_(20)A钢的耐蚀性.盐雾实验结果表明,未渗稀土样品2h出现锈斑,而渗稀土的样品10h也未出现锈斑.其它耐蚀性也有明显提高.The protected layer of oxide film with rare earths (RE) was formed by vapour co-pervade of elements La, Ce, C, N and B. In corrosion tests samples with RE is more corrosion-resistive than ordinary one. After being corroded for 10 h, there is no corrosive spot on samples with RE, and the ordinary one is almost covered with corrosive spots.

关 键 词：多元共渗钢 耐蚀性 稀土族
