一、概述金属的腐蚀是金属材料应用中急待解决的问题之一,它不仅造成了材料与能源的巨大浪费,而且威协着生产设备及人身安全.随着现代科学技术的发展,材料的应用范围日益扩大,使用条件更加苛刻,因此对材料的耐腐蚀性能也提出了更高的要求.虽然传统的表面防护方法(如电镀、化学镀、热浸镀、衬覆、涂料涂装及表面合金 I. Overview Metal corrosion is one of the urgent problems to be solved in the application of metal materials, which not only caused huge waste of materials and energy, but also cooperated with production equipment and personal safety.With the development of modern science and technology, Increasing range of applications, the use of more demanding conditions, the corrosion resistance of the material also put forward higher requirements.Although the traditional surface protection methods (such as electroplating, electroless plating, hot dip coating, coating, coating and surface alloy
