运用电化学法和失重法对低碳钢稀土-硼共渗层在强酸介质中的耐蚀性进行了研究，结果表明稀土-硼共渗可大大提高低碳钢的耐蚀性。
The corrosion resistance of low carbon steel rare earth-boron co-diffusion layer in strong acid medium was studied by electrochemical method and weight loss method. The results show that rare earth-boron co-permeation can greatly improve the corrosion resistance of low carbon steel.
