作为最轻的金属结构材料,镁在自然界中含量丰富,在地壳所有金属元素中含量排名第三位,被誉为“21世纪绿色金属工程材料”。我国是世界上镁资源大国,镁及其合金的产能占全球80%以上。如何把镁的资源优势转化为镁的产业优势,推动其在汽车、航空航天、电子乃至医疗、能源等领域的广泛应用,是摆在我国科研界和产业界人士面前的一项重要任务。针对在汽车、航空航天、电子以及生物医用等领域的实际应用,镁合金的表面力学性能、耐磨性和耐蚀性等尚有待提高和完善。为了延长镁合金的
As the lightest metal structural material, magnesium is rich in nature and ranks third in all the metal elements in the crust. It is known as “21st Century Green Metal Engineering Materials”. China is the world’s largest magnesium resource country, with more than 80% of the world’s capacity for magnesium and its alloys. How to transform the resource advantage of magnesium into the industrial advantage of magnesium and promote its extensive application in the fields of automobile, aerospace, electronics and even medical treatment and energy is an important task for the scientific community and industry in our country. For the practical applications in the fields of automobile, aerospace, electronics and biomedicine, the surface mechanical properties, wear resistance and corrosion resistance of magnesium alloy have yet to be improved and perfected. In order to extend the magnesium alloy
