N2 - This investigation aimed to study the influence of time of sandblasting, as a surface mechanical attrition treatment method, on the corrosion behavior of carbon steel in different solutions with different pHs. Optical microscopy, micro-hardness test, as well as Scanning Electrochemical Microscopy, were used to examine the affected area underneath the surface of the sandblasted specimens. The results of the electrochemical experiments showed significant improvement in corrosion resistance of the sandblasted specimens in the high alkaline solution. In neutral and acidic solutions, specimens sandblasted for 5 min showed superior corrosion resistance compared to the as-received and other specimens, sandblasted for longer period of time.
