Title: Corrosion properties of powder bed fusion additively manufactured 17-4 PH stainless steel

Abstract

The corrosion susceptibility of a laser powder bed fusion (LPBF) additively manufactured alloy, UNS S17400 (17-4 PH), was explored compared to conventional wrought material. Microstructural characteristics were characterized and related to corrosion behavior in quiescent, aqueous 0.6 M NaCl solutions. Electrochemical measurements demonstrated that the LPBF 17-4 PH alloy exhibited a reduced passivity range and active corrosion compared to its conventional wrought counterpart. Lastly, a micro-electrochemical cell was employed to further understand the effects of the local scale and attributed the reduced corrosion resistance of the LPBF material to pores with diameters ≥ 50 µm.

True active surface area as a key indicator of corrosion behavior in additively manufactured 316L stainless steel

Journal Article Cho, Seongkoo ; Buchsbaum, Steven F. ; Biener, Monika ; ... - Materials & Design

Laser powder bed fusion (LPBF) additively manufactured (AM) 316L stainless steels (SS) possess much more complex surfaces than their wrought counterparts which affects the corrosion behavior. Surface roughness, a typical metric for assessing corrosion of conventionally manufactured metals, is often ineffective as an independent parameter in characterizing corrosion of the AM metals for their higher surface roughness ranging from 5 to 50 µm. This study experimentally shows that the true active surface area (A_TA) is a proper parameter for quick assessment of localized corrosion response of AM 316L SS. Through the potentiodynamic polarization testing on surrogates under full immersion in 0.6 M NaCl solution, the pitting corrosion susceptibility was evaluated. While no consistent correlation to surface roughness was displayed, the pitting breakdown potential (E_p) showed a clear statistical trend atmore »« less

Effect of applied potentials on environmental cracking behavior of 17-4 PH stainless steel weldments

Journal Article Raja, K S ; Rao, K P - Corrosion

The effects of anodic, cathodic, and open-circuit potentials (OCP) on the environmental cracking behavior of 17% Cr-4% Ni (17-4 [UNS S17400]) precipitation-hardenable (PH) stainless steel (SS) welds subjected to different thermal treatments were studied. Sheets of 17-4 PH SS 1.5 mm thick and in solution-treated condition were full-penetration welded autogenously using the gas tungsten arc welding process (GTAW). Weldments were given one of two postweld heat treatments: direct aging and solution treatment + aging. Samples were aged at 480 C for 1 h, 510 C for 4 h, and 600 C for 4 h. Environmental cracking tests were conducted usingmore »« less

Porosity, roughness, and passive film morphology influence the corrosion behavior of 316L stainless steel manufactured by laser powder bed fusion

Journal Article DelRio, Frank W. ; Khan, Ryan M. ; Heiden, Michael J. ; ... - Journal of Manufacturing Processes

The development of additively-manufactured (AM) 316L stainless steel (SS) using laser powder bed fusion (LPBF) has enabled near net shape components from a corrosion-resistant structural material. In this article, we present a multiscale study on the effects of processing parameters on the corrosion behavior of as-printed surfaces of AM 316L SS formed via LPBF. Laser power and scan speed of the LPBF process were varied across the instrument range known to produce parts with >99 % density, and the macroscale corrosion trends were interpreted via microscale and nanoscale measurements of porosity, roughness, microstructure, and chemistry. Porosity and roughness data showed that porositymore »« less

Pitting behavior of type 17-4 PH stainless steel weldments

Journal Article Raja, K S ; Rao, K P - Corrosion

Electrochemical methods of measuring pitting potentials (E{sub pit}) were used to study the pitting resistance of type 17% Cr-4% Ni (17-4, UNS S17400) precipitation hardenable (PH) stainless steel (SS) weldments. The main objectives were to evaluate the pitting resistance of the base metal, the heat-affected zone (HAZ), and the weld metal portions of 17-4 PH SS welds welded autogenously using the gas tungsten arc welding (GTAW) process. Effects of different preweld and postweld heat treatments (PWHT) and of the weld heat input on pitting resistance were studied. Results showed a solution-treated base metal had a relatively lower pitting resistance. Inmore »« less

Pitting Corrosion in 316L Stainless Steel Fabricated by Laser Powder Bed Fusion Additive Manufacturing: A Review and Perspective

Journal Article Voisin, T. ; Shi, R. ; Zhu, Y. ; ... - JOM. Journal of the Minerals, Metals & Materials Society

Abstract 316L stainless steel (316L SS) is a flagship material for structural applications in corrosive environments, having been extensively studied for decades for its favorable balance between mechanical and corrosion properties. More recently, 316L SS has also proven to have excellent printability when parts are produced with additive manufacturing techniques, notably laser powder bed fusion (LPBF). Because of the harsh thermo-mechanical cycles experienced during rapid solidification and cooling, LPBF processing tends to generate unique microstructures. Strong heterogeneities can be found inside grains, including trapped elements, nano-inclusions, and a high density of dislocations that form the so-called cellular structure. Interestingly, LPBFmore »« less
