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

拟议的伙伴关系的目标是实现加拿大辛克鲁德有限公司、Unicast公司和不列颠哥伦比亚大学之间在开发用于高冲击、高磨损应用的新型双金属复合材料方面的新合作。在对全球制造业和技术部门至关重要的材料和大宗商品的开采方面，加拿大是世界领先者之一。开采有价值的材料(如石墨、镍、铜、钛、铀)的第一步是采矿作业，即开采富含矿物质的矿石，然后粉碎。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(卧式或立式)。这种破碎机中的岩石或矿石的破碎是由于锤子在通过破碎机时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)高的工作温度，3)高的机械动态载荷，4)高的磨损磨损。因此，开发能够在这种条件下存活的材料对于确保岩石破碎操作的足够性能和经济性至关重要。该联盟项目专注于双金属锤子的开发，该锤子由耐磨高铬白口铸铁(HCWI)与坚韧的高锰钢(HMS)刀柄配对而成。碳化钨(WC)增强体将通过冶金方法粘结到高强度碳化钨材料上，从而进一步提高其寿命、性能和耐磨性，预计将取得进一步突破。工业界和学术界HQP将从事新型锤子的材料开发、铸造、表征和使用中的评估。该项目的预期结果对加拿大辛克鲁德有限公司和Unicast Inc.都有直接和直接的影响，从而改善破碎机的性能，增强运营经济性，并为先进双金属材料的开发做出基础性的科学贡献。

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.
