由土壤中不同腐蚀程度钢片的电化学极化曲线,求得不同阶段的平均腐蚀速度。用显微观察、X衍射分析等方法对腐蚀表面、腐蚀产物进行观察研究,推测钢铁在土壤中的自然腐蚀速度不仅受环境的影响,还受到钢铁腐蚀过程中不同阶段的制约,并与腐蚀产物的量、形态结构、风化程度有关,是这些因素综合作用的结果。
The corrosion rates of mild steel in soil was studied by means of polarization curve measurements on steel specimens with various extent of corrosion in laboratory. The surface of the corroded specimens and corrosion products were observed and analyzed by microscopy and X-ray diffraction. Emphasis was placed on the relationship of corrosion rate variations with time. The results showed that soil corrosion of mild steel was not only influenced by surrounding media but also controlled by the amout, structure and efflorescence extent of corrosion products at different stages.
