Abstract

A cold spray process is a powder consolidation method that is capable of producing fully dense coating and bulk materials using accelerated particles that are deformed during high velocity impact onto a substrate. The process is seen as a viable method for additive manufacturing because of its high deposition rates and controllable spray jet. A process is developed to investigate the potential of the new cold spray additive manufacturing technique to make a copper-steel canister for the CANDU reactor spent fuel disposal. The thickness of a copper shell could be fabricated to be as thin as 3-10mm with the new method. This paper presents information on the process, and details the various strategies employed during the canister fabrication, structure and properties of copper layer and interface. Results indicate that cold spray can be used as a novel additive manufacturing technique for making bulk multilayer parts.
