Abstract
Plasma electrolytic oxidation (PEO) is a promising technology to improve the durability of aluminum alloys. However, herein we find that PEO process reduces the fatigue strength of the aluminum substrate, and the reduction varies with the PEO coating process. Detailed surface and sub-surface characterizations are conducted to understand the mechanism. Our study provides in-depth understanding on the effect of PEO coating on the properties of the base material, thus has important implications on their applications.
