大型重型机械机械零件表面硬化深度的检测对机械零件的强度或质量的保证具有重要意义。当其淬火钢件尺寸较大时，使用维氏硬度计进行破坏性检测是困难的。因此，需要采用无损检测的方法对硬化深度进行评价。硬化区域内的电磁特性低于未硬化区域。然后，通过检测这些电磁特性的差异，可以对硬化深度进行无损检测。本文采用演化策略方法，采用三维非线性电磁有限元法研究了表面硬化深度的高灵敏度检测方法。
The inspection of the surface-hardened depth of the mechanical part in a large-sized heavy industrial machine is important in the intensity or the guarantee of quality of these parts. When the size of its hardened steel parts is large, the destructive testing using the Vickers hardness tester is made difficult. Therefore, the non-destructive inspection method is needed for the evaluation of the hardened depth. The electromagnetic characteristic inside the hardened domain is lower than the non-hardening domain. Then, the non-destructive inspection of the hardened depth is possible by detecting the difference of these electromagnetic characteristics. In this paper, the high-sensitivity inspection method for detecting the surface-hardened depth is investigated by a 3-D nonlinear electromagnetic finite-element method using the evolution strategy method.
