电化学方法研究ZnAl、ZnAlRE合金在NaCl溶液中的腐蚀行为

Studies on the Corrosion Behavior of ZnAl and ZnAl RE Alloys in NaCl Solution by Electrochemical Method

用电化学方法研究了锌中掺入不同量Al、RE的锌合金在NaCl溶液中的耐蚀性能、硬度以及电化学行为的变化,并试图从合金结构上给予解释。

The variation of corrosion resistance in NaCl solution and hardness of Zn with addition of Al and RE were determined and explained by the-change of microstructure of alloys. The results obtained show that the addition of RE and Al increases the stability of Zn in NaCl solution and the hardness of the alloys.
