| 目的 获得A517Q海工钢长尺试样在热带海域的腐蚀行为。方法 通过贯穿海洋大气、飞溅、潮差和全浸区的长尺电连接试验进行研究。结果 试样在飞溅区的腐蚀速率最高，潮差区高潮位部位的腐蚀速率大于低潮位。全浸区上部的腐蚀速率高于其下部。各区带试样的腐蚀形貌存在显著差异。结论 三亚海域的海浪飞溅冲刷作用较大，水温和气温较高，导致A517Q长尺试样的飞溅区腐蚀严重。大量的海生物附着，Cr，Mo，Mn，Ni等合金元素的添加，减缓了全浸区的腐蚀。 |

| Objective To study corrosion behavior of long-size marine steel samples namely A517Q in tropical sea area. Methods The test was made based on the simulated long-size marine steel samples under influences of marine atmosphere, splash and tidal range throughout all immersion zones. Results The samples located at the splash zone corroded the fastest. Corrosion rates of samples at high tide zone were relatively higher than those at low tide zone. Corrosion rate of samples located more deeply were lower than those located more shallowly at the full-immersion zone. The micro-morphologies of marine steels varied in different zones. Conclusion The scouring action of wave splashing in Sanya sea area is large, in combination with high water and air temperature, the corrosion of A517Q long-size samples in the splash zone is severe. Due to the sea creatures growing over the surface and the addition of alloy elements such as Cr, Mo, Mn, Ni, the corrosion of samples at full-immersion zone is retarded. |
