| Abstract Scope |
ARL has been researching how shot peening can be used during the Cold Spraying process to increase the hardness and density of deposits where nitrogen is used as the carrier gas. During Cold Spray operations, using helium as the carrier gas allows for better consolidation of material, resulting in more favorable mechanical properties. Though the properties obtained with helium are better than those obtained using nitrogen, the high cost of helium makes the process less economically available. Shot peening is a widely used method for improving surface hardness through increasing dislocation density and grain refinement. This presentation will cover the methods used for shot peening assisted cold spray and show how these methods can be used to increase the hardness and density of niobium deposits sprayed using nitrogen carrier gas to the levels obtained when using helium. |
