Corrosion investigations of Additively Manufactured Alloys
Abstract
The purpose of the proposal is to investigate the corrosion behavior of additive manufacturing (AM) alloys and to develop strategies" to improve corrosion performance. In this effort localized corrosion known as pitting, stress corrosion cracking (SCC), and inter g"ranular cracking (IGC) will be addressed. AM alloys will be compared to the traditionally manufactured equivalents to gain an understanding to the elevated corrosion rates that have been observed in AM alloys. Oxide replacement will be investigated as a method to minimize the localized corrosion of AM materials. Oxide replacement works by selectively replacing flawed oxides with stable corrosion blocking oxides. This will be accomplished in two ways: First AM processed parts will be coated as a post processing step to eva"luate and understand the impact of surface oxide replacement, second AM feedstock will be treated and the impact of the powder will" be investigated with the goal of addressing corrosion while eliminating post processing steps.
