摘要:
通过自行设计的交流电场增强装置强化粉末法渗铝。该装置通过渗罐壁电极和置于渗罐中央的柱状电极,对置于两极之间的试样与渗剂施加交流电场。对低碳20钢进行中低温下的交流电场增强粉末法渗铝试验,研究新渗铝技术的特性。结果表明:施加适当的交流电场可以显著促进低碳20钢在中低温外热条件下的渗铝过程,改善渗层表层相结构; 在低至600 ℃的外热温度时,施加2 A电流的交流电场,渗铝层厚度可达到130 μm以上。
Abstract:
Pack aluminizing was carried out with a help of a selfdesigned alternating current field(ACF)apparatus.The ACF was appliedto the treated sample and the aluminizing agent with a columnshaped electrode located at the center of a pack container and another electrode onthe wall of the container. The alternating current field enhanced pack aluminizing(ACFPA)was employed to low carbon 20 steel at low and medium temperature.Characterizations of the new technology were investigated.The results showed that applying proper ACF could significantly accelerate the pack aluminizing process and improve phase structure of the surface layer.When aluminized for 4 h with an ACF current of 2 A,an aluminizing case of more than 40 μm could be formed at 600 ℃.
