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的是在Syncrude Canada Ltd.，Unicast Inc.和不列颠哥伦比亚大学开发一种新型的双金属复合材料，用于用于高影响力高浸润应用的新型合作。 加拿大是提取对全球制造业和技术领域至关重要的材料和商品的领导者之一。提取有价值的材料（例如石墨，镍，铜，钛，铀）的第一步是采矿作业，在其中提取富含矿物质的矿石并随后被压碎。 可以使用几种方法来实现压碎操作，其中最常见的是冲击器（水平或垂直）。这种破碎机中岩石或矿石的破碎是由于锤子在通过破碎机进食过程中对岩石的影响而发生的。 破碎环境代表了可能暴露于材料的最恶劣条件：1）极高的冲击负荷，2）高工作温度，3）高机械动态载荷和4）高磨损磨损。结果，能够生存这种条件的材料的开发对于确保岩石破碎操作的适当性能和运营经济至关重要。 该联盟项目的重点是由耐磨性高铬铁（HCWI）制成的双金属锤子的发展，并与坚硬的高锰钢（HMS）小腿配合。当将碳化钨（WC）钢筋兑换到HCWI材料上时，预计会有额外的突破，从而进一步增强其寿命，性能和耐磨性。行业和学术HQP将参与新型锤子的物质开发，铸造，表征和在职评估。 该项目的预期结果对Syncrude Canada Ltd和Unicast Inc.都有直接而直接的影响，从而改善了破碎机的性能，增强的运营经济性，并对先进的Bi-Metallic材料的发展做出了基本的科学贡献。
