Abstract
The present disclosure provides methods for enhancing adhesion between an additively manufactured aluminum alloy and an epoxy primer. The methods include performing a surface preparation process on a metal substrate including an aluminum alloy including a columnar structure including an α-aluminum matrix at least partially surrounded by a silicon phase. The methods include dispersing a sol-gel on a surface of the metal substrate. The methods include dispersing a primer on the sol-gel to form a sol-gel coating on the metal substrate.
