IN-SITU IMAGE GRAB AND ANALYSIS FOR PITTING PROCESS OF 304 STAINLESS STEEL
|
Abstract:
A method for grabbing and analyzing in-situ images was established to study pitting corrosion in 304 stainless steel. 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.
