In this research, the Synchrotron X-ray lithography (X-ray LIGA) was implemented to fabricate imitative Stress Corrosion Crack (SCC) for using as a reference specimen of electromagnetic NDT. A pattern of the imitative SCC was created by using X-ray LIGA with controllable shape and size in precise details. The pattern created had a high aspect ratio, which was formed on SU-8 polymer. As a preliminary experiment, the prepared pattern was inserted into a block of pure Nickel formed by an electroplating technique. To develop a reference comparable to stainless steel in terms of electromagnetic response, the technique called “Suspension Electroplating” was implemented to create a block of material from its powder form. A rough magnetic response was then measured by Eddy Current Testing (ECT). The results showed the possibility of creating the desired properties of stainless steel. The SCC pattern will be then inserted to become the reference specimen.

使用X射线LIGA和悬浮电镀技术的不锈钢模拟裂纹

在这项研究中，使用同步加速器X射线光刻（X射线LIGA）来制作模拟应力腐蚀裂纹（SCC），用作电磁NDT的参考样品。通过使用X射线LIGA创建精确SCC的图案，精确控制形状和大小。产生的图案具有高的长宽比，其在SU-8聚合物上形成。作为初步实验，将准备好的图案插入通过电镀技术形成的纯镍块中。为了开发在电磁响应方面可与不锈钢媲美的参考材料，实施了称为“悬浮电镀”的技术，以从粉末形式创建一块材料。然后通过涡流测试（ECT）测量粗略的磁响应。结果表明有可能产生所需的不锈钢性能。然后将插入SCC模式以成为参考样本。
