Mining Wear Test Facility

National Research Council Canada, Vancouver, British Columbia
What the facility does

Specializes in characterizing and understanding the wear and tribocorrosion performance of materials in mining and mineral processing

Area(s) of Expertise

The Mining Wear and Corrosion team at the National Research Council Canada (NRC) specializes in the characterization and performance evaluation of wear and corrosion materials for mining equipment, weld cladding for equipment repair, and research on effects and prediction of acid rock drainage and metal leaching. The team has world class experts and is equipped with a full line of lab testing equipment, including many unique test machines developed in-house, to most adequately simulate different wear and/or tribocorrosion situations in mining. Over the past 25 years, the team has run a Mining Materials Wear and Corrosion Consortium and supported many Canadian mining and oil sands companies and their materials suppliers with essential material evaluation data and in-depth insights into industry-relevant issues to assist in selection of the best possible material for a particular application or in the development/improvement of wear resistant materials.

Additionally, the team has extensive expertise in developing weld cladding and wire-arc additive manufacturing technologies for mining operations and sensors for wear monitoring, and in studying the mechanisms of acid rock drainage and metal leaching to enable better prediction and prevention solutions.
