摘　　要：局部腐蚀测试及评价一直是困扰腐蚀界的一大难题。针对CO2局部腐蚀的特征,研发了一种测量CO2局部腐蚀的测试仪。它能准确测定局部腐蚀的有关几何参数,定量评定局部腐蚀的破坏程度,并根据CO2局部腐蚀的特征,建立一种评定CO2局部腐蚀的方法。The testing and evaluation of the local corrosion caused by CO2 has been remaining a bottleneck in the field of corrosion science and engineering. Thus a test apparatus was developed to measure the local corrosion by CO2, based on taking into account the features of CO2 - induced corrosion. And a method was established for the measurement of the local corrosion caused by CO2. It was found that the apparatus could be used to accurately determine the geometric parameters con-cerning the local corrosion by CO2 and to quantitatively assess the destruction degree of the local corrosion by CO2 as well.
