Abstract Scope |
As metal additive manufacturing (MAM) advances there are still limitations to the type of materials that can be manufactured. Aluminum alloys are one of the more difficult materials to build with AM. To address this issue there are new alloys of aluminum that are being developed. One of these is A20X, while chemically it is much different than the typical AlSiMg aluminum alloys, it has superior mechanical properties which are currently being studied. The change in chemical composition may aslo affect the roughness and corrosion properties compared to other AM alloys.
In this study we will present the surface roughness of these alloys including SEM images of the as-built surface and compare to that of 316L SS, which is commonly printed across many machines. We will also present results on the susceptibility to corrosion of the as-built and electropolished material. |
