Abstract

As new additive manufacturing techniques are developed and optimized, the effects of these techniques on the resulting material properties must be characterized. One such property that is important in engineering design is corrosion resistance. The goal of this study is to assess the influence of Powder Bed Laser Fusion (PBLF) printing parameters and other traditional manufacturing processes on the corrosion resistance of AISI 4340 alloy steel parts. Corrosion performance was tested using atmospheric exposure, lab-scale environmental chambers and electrochemical techniques. Scanning electron microscopy, 3D digital microscopy and elemental analysis were employed to characterize the extent and morphology of corrosion degradation.
