PROJECT DETAILS:

This project aims to develop and implement new techniques for evaluating and improving the flow properties of water-atomized metal powders (Rio Tinto Metal Powders—PMRT). These powders and their blends are used as raw materials in advanced manufacturing processes, such as powder metallurgy (PM), additive manufacturing (AM), and metal injection molding (MIM). Improving the flow properties of these powders and their blends will enable the manufacture of high-performance products for the transportation and energy sectors. Furthermore, the completion of this project will position PMRT as one of the leading suppliers of steel powders to manufacturing companies. These companies are increasingly turning to PM, AM, and MIM processes with the clear goal of improving their overall competitiveness. As part of this project, water-atomized powders—whose production cost is significantly lower than that of gas- or plasma-atomized powders—will be used. Furthermore, these powders will be used in PM/AM/MIM processes, which allow for the fabrication of parts in their near-net-shape and thus with minimal material loss. These two characteristics, combined with the potential for recycling, would benefit both industry and the environment.

Finally, this research project will help train highly qualified technical personnel in the fields of materials science and advanced manufacturing to meet the growing demand from the manufacturing industry in Quebec and Canada.
