为了了解奥氏体不锈钢均匀表面的涡流阵列检测技术的检测能力，对比分析了2个奥氏体不锈钢工件均匀表面的检测结果，并与传统的溶剂去除型着色渗透检测技术的检测结果进行了对比。结果表明：对于奥氏体不锈钢均匀表面的检测，涡流阵列检测技术能够在一定程度上对表面开口浅缺陷进行深度评估，其表面开口浅缺陷和埋藏浅的近表面缺陷的检测能力也优于溶剂去除型着色渗透检测技术；对于表面开口应力腐蚀开裂和孔蚀的检测，前者的缺陷分辨力略低于后者，但缺陷显示对比度和缺陷检出率却高于后者。

To know the detectability of eddy current array testing technology for the uniform surface of the austenite stainless steel, the testing results of the uniform surfaces of 2 austenite stainless steel work piece were analyzed and compared with the ones of solvent-removal dye penetrate testing. The result shows that, for the testing of the uniform surface of austenite stainless steel, eddy current array technology can be used to estimate the depth of the surface-breaking shallow defect, and has better detectability for the surface-breaking shallow defects and the subsurface defects with a small buried depth than that of solvent-removal dye penetrate testing technology; the former has the lower defect resolution power but higher contrast and defect detectability than the latter for the surface-breaking stress corrosion cracking.
