The goal of the proposed partnership is to enable a new collaboration between Syncrude Canada Ltd., Unicast Inc. and the University of British Columbia on the development of a novel bi-metallic composite materials for high-impact high-abrasion applications. Canada is among the world leaders in the extraction of materials and commodities that are critical for global manufacturing and technology sectors. The first step in the extraction of valuable materials (e.g., graphite, nickel, copper, titanium, uranium) is a mining operation, where mineral-rich ores are extracted and subsequently crushed. The crushing operations can be achieved using several methods, with the most common being an impact crusher (horizontal or vertical). Fracturing of rocks or ores in such crushers occurs as a result of impact of hammers on the rocks during feeding through the crusher. The crushing environment represents some of the harshest conditions a material can be exposed to: 1) extremely high impact loads, 2) high operating temperatures, 3) high mechanical dynamic loads, and 4) high abrasion wear. As a result, development of materials capable of surviving such conditions is critical to ensure adequate performance and economy of operation for the rock crushing operation. This Alliance project focuses on the development of bimetallic hammers made of abrasion resistant high chromium white irons (HCWI) mated to tough high manganese steel (HMS) shanks. Additional breakthrough is expected when tungsten carbide (WC) reinforcements will be metallurgically bonded to the HCWI material, thereby further enhancing its lifespan, performance and abrasion resistance. Industry and academic HQP will engage in material development, casting, characterization and in-service evaluation of the novel hammers. The expected outcomes of the project have a direct and immediate implication for both Syncrude Canada Ltd and Unicast Inc., leading to improved performance of the crushers, enhanced economy of operation, as well as making a fundamental scientific contribution to the development of advanced bi-metallic materials.

拟议合作伙伴关系的目标是促进 Syncrude Canada Ltd.、Unicast Inc. 和不列颠哥伦比亚大学之间的新合作，开发用于高冲击高磨损应用的新型双金属复合材料。 加拿大在对全球制造和技术行业至关重要的材料和商品开采方面处于世界领先地位。提取有价值材料（例如石墨、镍、铜、钛、铀）的第一步是采矿作业，提取富含矿物的矿石并随后进行粉碎。 破碎操作可以使用多种方法来实现，最常见的是冲击式破碎机（水平或垂直）。在这种破碎机中，岩石或矿石的破裂是由于在通过破碎机进料期间锤子对岩石的冲击而发生的。 破碎环境代表了材料可能面临的一些最恶劣的条件：1) 极高的冲击载荷，2) 高工作温度，3) 高机械动态载荷，以及 4) 高磨损。因此，开发能够耐受此类条件的材料对于确保岩石破碎作业的足够性能和运行经济性至关重要。 该联盟项目的重点是开发由耐磨高铬白口铁 (HCWI) 制成的双金属锤，与坚韧的高锰钢 (HMS) 柄相匹配。当碳化钨 (WC) 增强材料通过冶金方式粘合到 HCWI 材料上时，预计将取得进一步的突破，从而进一步提高其使用寿命、性能和耐磨性。行业和学术总部将参与新型锤的材料开发、铸造、表征和在役评估。 该项目的预期成果对 Syncrude Canada Ltd 和 Unicast Inc. 都有直接和直接的影响，从而提高破碎机的性能，提高运营经济性，并为先进双破碎机的发展做出基础性的科学贡献。金属材料。
