Solid-state additive manufacturing of GRCop-42/84 copper alloys and their variants for combustion chamber liners

The partner organization, D.I. Self-Composite (DISC) Alloys Inc., specializes in large-format additive manufacturing for metals, with a particular focus on propulsion systems and aerospace applications. Leveraging advanced Cold Spray Additive Manufacturing (CSAM) technology, DISC Alloys has the capability to deposit multiple metals with precision and achieve high deposition rates (20 kg/h), enabling the production of complex, multi-material components.
Through this project, DISC Alloys aims to address a critical industry challenge: the high cost and limited availability of GR-42 and GR-84 copper alloys, which are essential for propulsion systems. These materials, while effective, present supply chain and economic constraints that hinder scalability and innovation in the aerospace sector.
By collaborating with academic expertise, DISC Alloys seeks to develop new materials with comparable or superior thermal and mechanical properties to GR-42 and GR-84. The anticipated outcomes include cost-effective solutions that enhance manufacturability while maintaining or exceeding performance standards.
The project’s success would yield significant social and economic benefits, including increased competitiveness for DISC Alloys in the aerospace market, reduced dependency on expensive and scarce materials, and fostering innovation that strengthens Canada’s position in advanced manufacturing and space technology sectors.
