| 【文章摘要】 The electronic speckle pattern interferometer was used to in situ monitor the pitting corrosion of 304 stainless steel at anodic polarization.The pitting current and pitting current density of a single pit were obtained.The pit growth was controlled by the corrosion products diffusion.The pit morphology was observed by a scanning electron microscope.The results showed that the pit was dish shaped,and the geometric parameters and pit growth time conformed to the function of Y = A+B1t+B2t2+B3t3. |
