本研究旨在研究喷砂时间作为一种表面机械磨损处理方法，对碳钢在不同ph值溶液中腐蚀行为的影响。利用光学显微镜、显微硬度测试以及扫描电化学显微镜对喷砂试样表面下的影响区域进行检查。电化学实验结果表明，喷砂试样在高碱性溶液中的耐蚀性显著提高。在中性和酸性溶液中，喷砂5分钟的试样比接收的试样和其他喷砂时间较长的试样具有更好的耐腐蚀性。
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.
