在硬切削领域，由于白层对零件的性能和寿命有重要影响，近年来对白层的研究越来越广泛和深入。然而，白层的性能，特别是其腐蚀性能，还没有得到很好的理解和明确的定义。本研究通过制作刀具磨损过程中不同亚表面微观组织（无明显变化、暗层、白层）的试样，利用电化学方法分析其电化学性能。结果表明，有白层和无白层试样的电化学性能差异明显。在3.5 wt.% NaCl溶液中，有白层的样品的电化学阻抗明显低于无白层的样品，其阳极稳态开路电位明显高于无白层的样品。也就是说，有白色层的试样在该溶液中容易发生腐蚀。结果表明，电化学法是一种可靠、方便、几乎无损的白层检测方法。
In the field of hard cutting, researches on white layer have become more extensive and in-depth in recent years, because white layer has an important influence on the performances and life of components. Nevertheless, properties of white layer, especially its corrosion properties, have not been well understood or clearly defined. In this study, specimens with different subsurface microstructures (no obvious change, dark layer, and white layer) were produced in the process of tool wear to analyze their electrochemical properties using electrochemical methods. It was found that electrochemical properties were distinct between specimens with and without white layer. A specimen with white layer had obviously lower electrochemical impedance and more anodic steady-state open-circuit potential than that without white layer in 3.5 wt.% NaCl solution. That is to say, specimens with white layer were prone to corrosion in this solution. The results also manifest that electrochemical method can be a reliable, convenient, and nearly nondestructive method to detect white layer.
