| 目的 探究表面喷丸处理对于Aermet100钢耐蚀性能的影响。方法 借助显微观察、电化学测量及XRD分析等手段，开展喷丸与未喷丸2类A100钢试件的中性盐雾试验。结果 腐蚀形貌上，两者腐蚀表面变化均为先出现红褐色物质，后出现红棕色与绿色絮状物，在出现变化的时间上相差约1个周期。随着腐蚀时间增长，XRD衍射峰发生右移，2类试件XRD结果均在144 h变化明显。中性盐雾试验电化学结果与海洋环境下电化学结果在溶液电阻、腐蚀产物电阻和腐蚀反应电阻上均有差异，自腐蚀电位略低，自腐蚀电流则低了2个数量级。结论 两者腐蚀现象规律一致，XRD衍射峰右移表明试件晶格参数变小。2类试件腐蚀速率呈现增加到减缓再到增加的趋势。喷丸能明显提高A100钢的耐蚀性。 |

| The work aims to investigate the effect of surface shot peening on the corrosion resistance of Aermet100 steel. By means of microscopic observation, electrochemical measurement and XRD analysis, the neutral salt spray test was carried out to the A100 steel specimens before and after shot peening. In terms of the corrosion morphology, the corrosion surfaces of two kinds of specimens firstly obtained reddish-brown material which then turned reddish-brown and green flocculent, and the time difference for these changes was about one cycle. With the increase of corrosion time, the XRD peaks shifted to the right, and the XRD results of the two kinds of specimens changed obviously at 144 h. The electrochemical results of neutral salt spray test were different from those under marine environment in solution resistance, corrosion product resistance and corrosion reaction resistance. The self-corrosion potential was slightly lower, while the self-corrosion current was two orders of magnitude lower. The corrosion laws of the two kinds of specimens are consistent and the XRD diffraction peak shifts to the right, indicating that the lattice parameters of specimens become smaller. The corrosion rates of the two kinds of specimens show a trend of increasing, slowing down and then increasing. Shot peening can obviously improve the corrosion resistance of A100 steel. |
