X80钢在不同土壤模拟溶液中的腐蚀行为
Corrosion Behavior of X80 Steel in Different Simulated Soil Solution
摘要
Abstract
The corrosion behavior of X80 steel in three kinds of simulated soil solution, was investigated by methods of mass loss measurement, scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) and X-ray diffraction (XRD). The results show that X80 steel is uniform corrosion in simulated solution of Shanshan and Xinzhou soil, and pitting corrosion occurs on X80 steel in simulated solution of Zhangshu soil. The ranking of the corrosion rate of X80 steel in different simulated solution is Zhangshu, Xinzhou and Shanshan. The salt-crystallization of CaSO4 ·2H2O, which could inhibit the erosion effects of Cl- and dissolved oxygen on X80 steel, continuously deposit on the surface of corrosion products in Shanshan simulated solution, and slow down the uniform corrosion rate as well. However, the corrosion product layer that could not provide effective corrosion protection for X80 steel in Zhangshu simulated solution, makes the corrosion of X80 steel become more serious with the increasing of immersion time, and finally results in pitting corrosion of X80 steel.关键词
