KANG Yi-hua, YE Zhi-jian, SUN Yan-hua, et al. A surface defect detection method for metal material using capacitive sensor[J]. 2014, 33(12): 127-129. DOI: 10.13873/J.1000-9787(2014)12-0127-03.
Propose a simple and effective surface defect detection method for metal material
based on principle of capacitive sensor.Working principle of capacitive sensor is introduced
basic method surface defect detecting of metal material
utilizing single electrode sensor is described and the corresponding circuit model is provided.A series of experiments are designed to verify the feasibility of this method.The experimental results show that capacitive sensor is sensitive to surface defect of metal material
the detection method can be quickly and easily implemented through monolithic integrated electric field imaging integrated device MC33794
which provides a quick
convenient and effective detection method for surface defects(such as corrosion) for metal material.
