Magnesium is necessary trace metal elements in the human body, has good biological compatibility and biodegradable properties. With the development of intravascular therapy techniques, endovascular stent implantation has become one of the most effective methods in the treatment of cardiovascular disease. Capillary material of magnesium alloy is a kind of important magnesium alloy structure, can be used as alternative to aluminum alloy and other metal thin-walled right choice, to achieve the effect of weight loss, energy saving. Has been widely used in communications, electronics, aviation, spaceflight, automobile, motorcycle industry, household appliances, textile printing, packaging, war industry and medical intervention treatment and other industries. Degradation behavior of magnesium and
