摘要:
为探明工业纯钛TA₂在热带海域中的腐蚀与污损，在南海三亚海洋环境试验站进行了为期0.5年、1年、2年、3.5年四个周期的全浸试验。对3.5年周期的试验样品，利用解剖镜鉴定了生物污损群落的组成、利用金相显微镜观察、X射线衍射、扫描电子显微镜（scanning electron microscopy，SEM）及红外光谱分析技术分析了基体和腐蚀产物的微观形貌，确定了钛板表面的元素和产物。结果表明，钛板表面由基底的二氧化钛膜、管栖多毛类、微藻等的微型生物和有机、无机颗粒组成的腐蚀产物皮膜所覆盖。和同纬度热带海域相比生物污损轻微，试板上（可视生物）仅有3~5个而且种类少、数量少、个体小。钛板基体表面未发生局部腐蚀。

Abstract:
To investigate the corrosion and fouling of industrial pure titanium TA₂ in the tropical waters, a full immersion test was carried out for four cycles within 6 months, 1 year, 2 years, and 3.5 years at the Sanya marine environmental test station in the South China Sea. For the 3.5 year cycle test samples, the biofouling community composition was identified by anatomical imitation, and the microstructure of the matrix and corrosion products were observed by metallographic microscopy, X-ray diffraction, scanning electron microscopy (SEM), and infrared spectroscopy, and the elements and products on the titanium surface were determined. The results show that the surface of the titanium plate substrate was covered with TiO₂ film; microorganism such as tubular hairy and microalgae; and a corrosion product film composed of organic and inorganic particles. Compared with the tropical waters of the same latitude, the biological contamination in the test station is slight. There were only 3-5 visible organisms on the test plate, and the numbers of species and individuals were few. Moreover, there was no local corrosion on the titanium plate surface.
