破茬圆盘刀点蚀损伤的声发射评价

摘要

通过实验室腐蚀环境模拟实验，研究点蚀过程中腐蚀损伤程度及腐蚀声发射信号随腐蚀时间的变化规律，获得了腐蚀损伤与声发射参数之间的变化关系。结果表明，声发射技术可用于探测早期腐蚀、研究腐蚀发展规律、监测和评估腐蚀损伤等方面。%By the simulation test of corrosion environment in the laboratory , change disciplinarian of corrosion degree and AE signal with corrosion time has been studied , and change relation between corrosion degree and AE parameter has been achieved .This explains that AE technology can be used in detecting forepart corrosion , researching corrosion growing or-derliness , inspecting and evaluating corrosion damage .
