Abstract
Cold Spray Additive Manufacturing is a technology capable of mass manufacturing components with complicated geometry and coating substrates in hard-to-reach areas. In addition, cold spray also has the ability of conducting a green manufacturing process, with zero waste of renewable feed material, and zero gas and chemical emission. This paper investigates solely cold spray as an additive manufacturing technology with cork as the natural material. CFD results were used to predict the physical behavior of air and the cork particles. After unsuccessful coatings, final results showed that when moisture is added, cork is successfully cold sprayed, and agglomeration is experienced. Following these results, high speed camera and Hopkinson bar tests concluded that pressure is the only significant parameter that drastically effects the disposition quality of the cork coating. This is the first reported result of cork powder being cold sprayed, in addition to groundbreaking results of successfully coating an Aluminum substrate without a binder. Key words: cork, powder, additive manufacturing, natural materials, cold spray, binder, deposition efficiency, coating, high speed camera, Hopkinson bar.
