Mechanical Properties of Aluminum/Alumina Mixture by Process of Cold Spray

摘要: Cold Spray technology has been used in repairs and strengthening of surfaces of various metals and metal alloys, but little is known about the mechanical properties of the deposits made to repair these objects. This research is being conducted to find out if using Cold Spray as repair substance, will it have similar properties/behaviors as the metal it is filling in. In this report the authors will test the mechanical properties of Cold Sprayed aluminum and alumina mixtures. This research will result in the knowledge of what mixtures of aluminum and alumina have a higher tensile strength and the most ideal mechanical properties. Some findings that have been made in this research have been that a mixture of aluminum 2024 and silicon carbide requires a high pressure system which is unavailable at this time. We also have found in our microhardness testing, the strongest points of the deposit are the center and the edges of the deposit. The weaker part of the deposit lies in the high point of the deposit.
