舰船重点部位腐蚀监测系统研究

Research of corrosion-monitoring system on key parts of ship

根据舰船重点部位的腐蚀环境、特点和机理,对比分析了常用监测技术原理、方法和局限性,确定联合采用电化学噪声技术和传感器技术,研制出了集＂测量、采集和存储＂于一体的舰船腐蚀监测系统,其数据采集频率可高达10 Hz、电位测量范围为-4 000~4 000 m V,精度达到1 m V。

A set of corrosion detection system, which simultaneously possesses ＂measure- ment, collection and storage＂ functions, has been successfully designed and developed using of electrochemical noise technology and sensor technology on the basis of the comparative analy- sis of the common corrosion monitoring technology, according to the corrosion environment, characteristics and mechanism of the key parts of ship; the corrosion characteristics and behav- iors of the key parts of ship. For the corrosion detection system, the data acquisition frequency can be as high as 10 Hz, the potential measurement range is from -4 000 mV to 4 000 mV and the measurement accuracy to potential error is 1 mV.
