离子束技术(包括离子注入、离子束混合、离子束分析等)在腐蚀科学领域中的应用是近十年来一个引人注目的新发展。 据工业发达国家估计,每年因材料、设备腐蚀造成的直接损失约为当年国民经济总产值的2—4％,例如美国1982年全国因腐蚀而造成的经济损失就高达1260亿美元,我国在1980年估算的腐蚀损失约200亿人民币。随着我国四化建设的迅速发展,金属腐蚀与防护的研究已成为当前一个急待进行的重要课题。
The application of ion beam technology (including ion implantation, ion beam mixing, ion beam analysis, etc.) in the field of corrosion science is a notable new development in recent ten years. According to the estimates of the industrialized countries, the annual direct losses caused by the corrosion of materials and equipment are about 2-4% of the total national output value of that year. For example, the economic losses caused by corrosion in the entire United States in 1982 were as high as 126 billion U.S. dollars. In 1980, Estimated annual loss of about 200 billion yuan of corrosion. With the rapid development of the four modernizations in our country, the research on metal corrosion and protection has become an urgent issue to be carried out at present.
