储罐长期腐蚀状态下的声发射监测分析

摘要

通过对一充水存放超过2年的储罐试验模型进行声发射腐蚀监测，分析其在长周期腐蚀状态下的声发射信号特征规律，研究其与腐蚀发展各阶段的对应关系，从而掌握储罐腐蚀机理和规律，形成对储罐腐蚀更深入的认识，为后续储罐在线评价及腐蚀防护等提供可靠的理论支撑。%With the AE corrosion monitoring in a water iflling tank more than 2 years, this article analyzes the AE signal characteristics of long period corrosion, researches the corresponding relationship of each corrosion development stage. In the end, it grasps the goal of mastering corrosion mechanism and law more in-depth understanding of tank corrosion, providing reliable theoretical support for subsequent tank online evaluation and corrosion protection, etc.
