Abstract
Aluminum foam material has unique properties that make them useful in applications to the automobile, construction and railroad industries. In this study, aluminum was plasma-treated using nitrogen gas to improve fracture behavior between aluminum and aluminum foam material. SLS specimens were used for fracture tests. They were performed using plasma-treated and untreated aluminum/aluminum foam specimens. It was shown that the fracture strength and the tincture toughness of aluminum/aluminum foam were improved ${\sim}86%\;and\;{\sim}250%$, respectively when the aluminum was plasma-treated using nitrogen gas.
