水陆装甲车车体锈层进行了研究，研究表明：锈层中含有Cl-，锈层主要由α-FeOOH、β-FeOOH、γ-FeOOH、γ-Fe2O3、Fe3O4以及α-Fe等相组成，同时还残留有极少量的绿锈GR*(I).结合水陆装甲车的使用环境(海水、淡水，干湿交替)，对锈层各相的成因进行了分析.内锈层致密，大蚀坑下有小蚀坑，锈层中包含有呈小岛状弥散分布的Fe基体，均匀腐蚀与局部点蚀共同造成了材料的腐蚀破坏. |
| 关 键 词： | 锈层 均匀腐蚀 |

| Abstract: | Iron rusts on body of amphibious vehicles after service for 20-30 years in south-east coastal atmospheres have been analyzed by means of x-ray diffraction,SEM and EPMA.It was found that the phase components of the rust were goethite,akageneite,lepidocrocite,maghemite,magnetite and alpha-iron,as well as a little of the so called green rust *(I).Chloride ion was detected in the rusts and the influence of chloride on the formation of the main iron oxides and ferric hydroxides was also analyzed.Several smaller pits lying in a larger pit and some islet-like dissipated iron particles in the rusts showed that the corrosion failure of carbon steel was due to uniform corrosion and pitting corrosion. |
| Keywords: | iron rust phases uniform corrosion pitting Cl - wet-dry alteration amphibious vehicles |
