Abstract Scope |
Additive manufacturing can greatly reduce cost and waste in the production of a small number of parts, especially those that are no longer in production, as compared to traditional manufacturing methods. However, as the same machine may be used to print many different powders, the potential for contamination exists. This contamination can then lead to galvanic corrosion, as two dissimilar metals are now in contact, which can greatly accelerate the corrosion of the more active metal. The effect of metal contamination on the degradation of the mechanical properties of AlSi10Mg with various levels of contamination must be determined in various corrosive environments, especially if it will be used in long-term applications. The research presented here will compare the mechanical and physical degradation of parts produced without contamination and with three small levels of contamination, after exposure to three corrosive environments, including saltwater immersion, salt-fog, and acidic salt-fog. |
