Small quantities of needed parts, for equipment that is no longer in production, can be made using additive manufacturing, at less cost and waste than large scale manufacturing methods. Defects caused by processing parameters that create voids and contamination from previously run powders can both produce locations that concentrate mechanical stresses and corrosive ions. Determining how these defects, both voids and contamination, interact with the base AlSi10Mg metal in corrosive environments is important, especially if these parts are planned for long-term applications. The research presented here will compare the behavior of parts produced using optimal parameters to parts with defects from either processing parameters or Inconel contamination in two corrosive environments – saltwater immersion and salt-fog. The various defect sizes and environments will be compared to determine how the processing parameters affect corrosion behavior and how corrosion affects mechanical behavior.
