Abstract
This study investigates the corrosion behavior of Inconel 625 fabricated by Wire Arc Additive Manufacturing (WAAM). Studies revealed that changes in microstructure occur from the bottom surface of the deposited layer to the top surface as follows: (i) bottom layer: fine cellular grains, (ii) middle layer: cellular dendritic structure and (iii) top layer: coarse dendritic structure. The results show that the electrochemical parameters of the samples in each region are similar to wrought Inconel 625. While corrosion performance of the deposited sample along the height is not uniform, the corrosion resistance of the top region is found to be better than that of the other regions, which can be attributed to the less precipitation of metal elements caused by the denser grain arrangement.
