Analysis of Thermally Oxidized Surfaces of Additive Manufacturing Metal Powders Using Triboelectric Charging

Applied Sciences
In powder-based additive manufacturing (AM), thermal exposure during processing can modify powder surface chemistry and promote oxide growth, even under inert atmospheres from residual oxygen contamination.

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Assessment of chromate and chromate-free conversion coatings for the corrosion protection of aerospace aluminum alloy [PDF]

, 2013
Aerospace aluminum alloys, especially the most commonly used AA 2024 T3 alloy is often susceptible to corrosion in chloride containing environment. These alloys are phase separated, highly complex metal-in-metal composites and tend to have weakness ...

Impact of the Process Atmosphere During Hot Isostatic Pressing on the Near‐Surface Composition of an Additively Manufactured Austenitic High‐Interstitial Steel

Advanced Engineering Materials, EarlyView.
A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.
