[美国]钢、铝及其他金属结构件的腐蚀,不仅造成各国数千万美元的维修及部件更换费用,而且也威胁到安全。例如:对于舰艇、坦克、飞机及其他设备的防腐蚀处理,每年消耗军费2.29亿美元。因腐蚀而更换受损材料及部件的费用,约占工业发达国家GDP总量的3.5%,同时还有相应的生产损失、环境影响、运输中断及伤亡事故的费用。 [United States] Corrosion of steel, aluminum and other metal structures not only cost tens of millions of dollars in repairs and parts replacement in many countries, but also threaten safety. For example: The anti-corrosion treatment of ships, tanks, airplanes and other equipment consumes a total of 229 million U.S. dollars each year. The cost of replacing damaged materials and components due to corrosion accounts for about 3.5% of the GDP of industrialized countries, with consequential losses in production, environmental impacts, disruptions in transportation and casualties.
