扫描电化学技术在腐蚀研究中的应用

摘要

With the development of corrosion electrochemistry research technique, scanning electrochemical microscopy（SECM） with spatial resolution power can be used to study the mechanisms of pitting corrosion and stress corrosion cracking of alloys. M370 scanning electrochemical workstation was used to study the corrosion-resistance of aluminium alloy and stainless steel and characterization of stress corrosion crack.%随着腐蚀电化学研究技术的发展，研究合金点腐蚀和应力腐蚀开裂等机理，需要运用具有空间分辨度的原位扫描电化学技术。本工作采用M370扫描电化学工作站对铝合金和不锈钢试样的腐蚀过程，对不锈钢试样应力腐蚀开裂进行了表征，并介绍了扫描电化学技术在腐蚀研究中的应用。
