DEVELOPMENT AND APPLICATION OF ATMOSPHERIC CORROSION DETECTING INSTRUMENT BASED ON GALVANIC CORROSION
基于电偶的大气腐蚀性检测仪的研制及应用

The detecting instrument based on galvanic corrosion was developed for atmospheric corrosion.The corrosivity of atmosphere was studied on the basis of quantity of electricity got by analog integration of galvanic current.The value of the quantity of electricity was obtained by integrator's reset times.It was used to detect the atmospheric corrosivity for LY12 alloy covered with thin layer electrolyte with different Cl - concentrations.The detecting instrument has the advantages of easy-to-operate,reliable and portable so can be used to test and detect in the field.
