Using a self-developed Visual C++ program, images obtained upon potentiostatic polarization were analyzed. It was found that there was a liner relationship between pitting ratio and reaction electric quantity. Besides, lots of small pits became a larger pit, and grays moved towards smaller values and double peaks were observed on the gray histograms when pitting corrosion happened. Key words:  image processing      stainless steel      pitting      Received:  18 September 1998      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1998/V34/I9/966 1 Itzhak D, Dinstein I,Zilberberg T CorrosSci, 1981; 21: 17 2 Costa J M , Sagues F, Vilarrasa M.
