摘要

铝合金通常用于飞机工业，但它容易腐蚀，需要进行适当的检查。涡流检测是目前应用广泛的航空金属无损检测技术。本文研究了飞机铝板腐蚀损失的估算方法。Al1100、Al2024、Al7075厚度为2mm。用铝板在盐酸中制造人工损伤。采用涡流测试法(ET)检测了腐蚀引起的厚度损失，并与三坐标测量机(CMM)测量结果进行了比较。结果表明，利用涡流集肤深度频率可以估计腐蚀引起的厚度损失。但在实际应用中，可以根据腐蚀速率来推测出镀层深度，这样可以减少检测时间。本研究采用动电位法测定腐蚀速率。它可以用于估计适当的检测间隔的厚度损失。

Eddy current evaluation for thickness loss estimation of aluminum alloys used in aircraft structures

Aluminum alloys are commonly used in the aircraft industry but it tends to corrode and needs to be inspected properly. Eddy current testing is the widely used non-destructive testing (NDT) for aircraft metals. This research studied estimating the thickness loss due to corrosion in an aircraft aluminum sheet metal. The Al1100, Al2024, and Al7075 were 2 mm thick. Aluminum sheet metals were used to create artificial damage in hydrochloric acid. The thickness loss due to corrosion was inspected with eddy current testing (ET) and compared with the measurement from the coordinate measurement machine (CMM). The results showed that the thickness loss due to corrosion could be estimated using the eddy current skin depth frequencies. However, in the practical application, the skin depth could be guessed from the corrosion rate which could reduce the inspection time. In this research, the corrosion rate was measured by using potentiodynamic measurement. It can be used for estimating the thickness loss for an appropriate inspection interval.
