(DURIP) KINETIC SPRAY DEPOSITION SYSTEM FOR RESEARCH ON AGILE MANUFACTURING OF NEXT-GENERATION STRUCTURAL AND PROPULSION SYSTEM MATERIALS
Abstract
Members of the Department of Materials Science and Engineering (MSE) at UCI, the Advanced casting Research Center (ACRC)), and the Institute for Design and Manufacturing Innovation (IDMI) are currently collaborating with ARL, ARO, ONR, AFOSR, DLA and SERDP on several fundamental research programs with relevance to the materials and structures needs of the defense industry. The kinetic spray deposition (Cold Spray) system instrumentation requested under this proposal enables additive deposition and manufacturing through solid-state consolidation of materials. Particles are accelerated to high speeds with a gas jet nozzle, impact a substrate, undergo extreme plastic deformation, and bond to the substrate or previously deposited material while remaining in the solid state – i.e., without undergoing melting and solidification. The requested instrumentation would provide critical capabilities enabling: (1) the development of an improved understanding of the fundamental materials behavior during cold spray deposition and linkages between intrinsic material characteristics and controllable processing parameters; (2) exploration of the potential uses of cold spray deposition for near-net shape additive manufacturing of materials and topologically complex structures via solid-state consolidation; and (3) the development of approaches to deposit coatings and multilayers of emerging compositionally complex alloys and refractory materials that are not amenable to existing coating deposition approaches (such as thermal spray).
