Clarifying the cracking behavior and crack suppression of Zr-based conversion coatings on AA6016 Al alloy
Source abstract
Abstract
In this work, ZrCC with various additives were prepared on AA6016 Al alloy, and their cracking behavior under multiple thermal aging protocols were systematically investigated. The results demonstrated that dehydration was the dominant mechanism responsible for coating cracking. The incorporation of Cu2+ ions and aminosilane modulated the coating growth kinetics, reducing its water content and effectively mitigating cracking formation. Furthermore, the enhanced interactions between Cu and Zr species within the coating further promoted crack suppression. This study provides new mechanistic insights into ZrCC cracking and offers viable strategies for suppressing crack formation, contributing to the development of high-performance industrial coating systems.
