对添加RE(稀土)和Mg的热浸镀铝层的耐蚀性能进行了试验研究,给出了镀层在各种介质的腐蚀试验结果,并对腐蚀形貌进行了观察和分析。结果表明,适量的RE和Mg能改善镀层的耐蚀性。
The corrosion resistance of hot dip aluminized layer with RE (rare earth) and Mg added was studied. The corrosion test results of the coating in various media were given. The corrosion morphology was also observed and analyzed. The results show that proper amount of RE and Mg can improve the corrosion resistance of the coating.
