Abstract Scope |
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 Spray 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 fabricated is about 3-10mm with the new method. This presentation presents information on the process, and details the various strategies employed during the die fabrication, structure and properties of steel layer and interface. Sintering is applied to utilize reactions between the particles and obtain steel layer structure with the high hardness. |
