摘要：金属管材的腐蚀和结垢是地热资源开发利用中存在的主要问题。采用扫描电子显微镜(SEM)、能谱仪(EDS)、X射线衍射仪(XRD)、全浸均匀腐蚀实验和电化学测试法对比研究了化学镀镍磷钢管、304不锈钢管和20#碳钢管在模拟地热水(广东省和平县)中的耐蚀阻垢性能。结果表明,化学镀镍磷钢管的表面能较低,生成的CaCO_3污垢稳定性较差,不易在表面聚集;此外,化学镀镍磷钢管在模拟地热水中产生的表面钝化膜致密稳定,能有效保护基材免受腐蚀。因此,化学镀镍磷钢管在模拟地热水中的耐蚀和阻垢性能明显优于304不锈钢管和20#碳钢管。
One of the major problems associated with the utilization of geothermal energy is corrosion and scal- ing. Scanning electron microscopy（SEM）, energy dispersion spectrometry（EDS）, X-ray diffraction（XRD）, im- mersion corrosion and electrochemistry test were used to study and compare the anti scaling and corrosion re sistance performance of Ni-P electroless coating steel pipes, 304 stainless steel pipes and 20 carbon steel pipes in a simulated geothermal water environment（Heping county, Guangdong province）. The results show that the surface energy of Ni-P electroless coating steel pipes is low, and the scales on the surface is not stable which makes it difficult to aggregation. In addition, the passivation film produced on the surface of Ni-P electroless coating steel pipes in the simulated geothermal water is compact and stable, which can protect the pipes from corrosion effectively. Therefore, the anti scaling and corrosion resistance performance of Ni P electroless coat ing steel pipes in the simulated geothermal water is obviously better than that of 304 stainless steel pipes and 20 carbon steel pipes.
