Abstract
A new electrochemical etching method for the Mg-Ca-Zn alloy, including a new electrolyte solution and technological parameters, was developed in this paper. The EDTA in the electrolyte solution can chelate with Mg2+ and form the Mg-EDTA complex, which can play a crucial role in the selective etch. The lateral etching in the Mg-Ca-Zn alloy could be restrained while the vertical etching was enhanced through adjusting the stirring speed to obtain the reasonable electrolyte fluid field. In addition, surface fluorination treatment for the etched Mg-Ca-Zn alloy was also developed in this paper, which showed the corrosion behavior was improved..
