Summary	Graphene is an advanced nanomaterial characterized as a single plane of carbon atoms. Although first officially fabricated in 2004, it is likely that graphene had been produced, without knowing it, for centuries, e.g., evidence exists of the presence of carbon nanotubes (rolled up tube of graphene) in wootz steel (commonly known as Damascus steel) forged in late 16th century India. In all this time, however, an intentional application that made use of graphene's amazing properties has yet to be commercialized. One avenue for the application of graphene is in composites where the properties of graphene are used to improve the properties of the composite bulk. Graphene combined with metal feedstock used in cold spray and in 3D-printing may improve properties like adhesion and wear resistance in the case of aluminum cold sprayed coatings or both wear and corrosion resistance in the case of 3D-printed stainless steel. This study hopes to elucidate the effects of adding graphene in these additive manufacturing techniques including any changes to mechanical properties, adhesion strength, corrosion behavior, and wear resistance. In doing this, the study aims to highlight the advantages and disadvantages of fabricating graphene laden metal matrix composites in naval applications.
