摘要

采用电镀镍和包铝两步法制备的功能分级 Ni2Al3 涂层可以改善低碳钢的硬度和其他表面性能特征。然而，涂层与基体之间的附着力是影响这些性能的重要因素。本研究的主要目的是介绍一种测定 Ni2Al3 涂层附着力的测试方法，包括两种工具，即微划痕测试仪（MST）和 WS-2000 自动划痕测试仪，用于测量涂层附着力和观察划痕形态。结果显示，MST 的附着力约为 14 N，相当于 WS-2000 的 56 N。随着载荷的增加，划痕逐渐变大、变深。最后，表面形态出现裂纹，表明涂层已经失效。

MEASUREMENT OF ADHESION PROPERTIES OF Ni2Al3 COATING WITH A MICRO SCRATCH TESTER AND AUTOMATIC SCRATCH TESTER

A functionally graded Ni2Al3 coating, prepared with a two-step method of nickel electroplating and pack aluminizing, can improve the hardness of low-carbon steel and other surface performance features. However, the adhesion between the coating and the substrate is an important factor affecting these properties. The primary purpose of this study was to introduce a test for determining the adhesion of the Ni2Al3 coating, which included two tools, namely a micro scratch tester (MST) and a WS-2000 automatic scratch tester, used for measuring the coating adhesion and observing the scratch morphology. Results show that the adhesion is about 14 N according to the MST, which is equivalent to 56 N obtained with WS-2000. As the load increases, the scratches gradually become larger and deeper. Finally, the surface morphology shows cracks, indicating that the coating has failed.
