Development and characterization of composite materials for high-impact high-wear applications.

拟议的合作伙伴关系的目标是使加拿大合成原油有限公司之间的新合作，单播公司与不列颠哥伦比亚省大学合作，开发一种新型双金属复合材料，用于高冲击高磨损应用。 加拿大是世界上提取对全球制造业和技术部门至关重要的材料和商品的领导者之一。提取有价值材料的第一步（例如，石墨、镍、铜、钛、铀）是一种采矿作业，其中提取富含矿物质的矿石并随后将其粉碎。 破碎操作可以使用几种方法来实现，最常见的是冲击式破碎机（水平或垂直）。在这种破碎机中的岩石或矿石的断裂是由于在通过破碎机进料期间锤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，开发能够经受住这种条件的材料对于确保岩石破碎操作的足够性能和操作经济性至关重要。 该联盟项目的重点是开发由耐磨高铬白色铸铁（HCWI）与坚韧高锰钢（HMS）柄相匹配制成的锤头。当碳化钨（WC）增强材料与HCWI材料进行热塑性结合时，预计会有进一步的突破，从而进一步提高其寿命、性能和耐磨性。工业和学术HQP将从事材料开发，铸造，表征和在服务中评估的新锤。 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，从而改善破碎机的性能，提高运行的经济性，并为先进双金属材料的发展做出基本的科学贡献。

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.
