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 Low Pressure Cold Spry 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 low pressure cold spray additive manufacturing technique to make rebuilding of molds and dies. The thickness of a steel 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 die fabrication, structure and properties of steel layer and interface. The low pressure cold spray is shown to be used as a novel additive manufacturing technique for making bulk multilayer parts. |
