Development of electroplated cu-sn-zn and Cu-Ni-Zn ternary alloys for coinage application

加拿大皇家造币厂（RCM）为加拿大生产流通硬币，并为世界上其他75个国家生产硬币。他们是铸造行业的全球领导者，其突破性的专利多层电镀（MPP）技术是世界上最先进的电镀技术之一，已被超过25个其他国家采用。除了通过该技术节省成本和提高硬币质量外，它还通过更可靠的电磁签名生产具有增强安全特性的硬币。然而，随着金属价格的不断上涨，需要不断创新，以满足不断增长的降低成本的需求。在不影响质量和 ** 耐用性的情况下，** MPP技术的应用进一步降低生产成本的一种可能方法是创造性地用三元合金取代目前使用的二元合金涂层。因此，RCM正在与马尼托巴大学合作，在这项拟议的研究中，开发 ** 新的电镀铜-锡-锌（Cu-Sn-Zn）和铜-镍-锌（Cu-Ni-Zn）三元合金。研究结果将导致生产成本降低，而不会危及可可质量和耐用性，这将 ** 转化为增加铸币税和加拿大的收入。除了RCM之外，电镀还广泛用于其他关键行业的涂层金属产品的制造，包括 ** 汽车，航空航天，生物医疗和能源，这些对加拿大经济至关重要。除了将培训的HQP之外，实现更经济和有效的电镀程序，作为这项拟议研究的贡献，肯定会对这些行业有益。** 研究成果的传播将导致制造程序的改进，这将可能导致成本降低，** 增加来自加拿大以外的业务，创造就业机会和增强加拿大经济，同时也有助于 ** 加拿大在先进电镀技术方面的竞争力。

The Royal Canadian Mint (RCM) produces the circulation coins for Canada and has produced coins for over**75 other countries around the world. They are a global leader in the minting industry and their ground-breaking**and patented multi-ply plating (MPP) technology is one of the most advanced electroplating technologies in the**world, which has been also adopted by over 25 other countries. In addition to the cost savings and improved**coinage quality enabled by the technology, it also produces coins with enhanced security feature through a**more reliable electromagnetic signature. Nevertheless, continuous innovation is required to address the**ever-increasing need to reduce costs as the prices of metals keep rising. A possible approach with the**application of the MPP technology to further reduce production costs, without compromising the quality and**durability, is to creatively replace the currently used binary alloy coating on coins with ternary alloys.**Therefore, the RCM is collaborating with the University of Manitoba, in this proposed research, to develop**new electroplated copper-tin-zinc (Cu-Sn-Zn) and copper-nickel-zinc (Cu-Ni-Zn) ternary alloys. The results of**the research will lead to lower production costs, without jeopardizing coinage quality and durability, which will**translate to increased seigniorage and revenue generation for Canada. Aside from the RCM, electroplating is**widely used in the manufacturing of coated metallic products in other key industry sectors, including**automotive, aerospace, bio-medical and energy, which are vital to the Canadian economy. In addition to the**HQP that will be trained, the realization of more economical and effective electro-plating procedures, as a**contribution from this proposed research, will certainly be beneficial to these industries. Dissemination of the**research results will lead to improved manufacturing procedures, which will potentially result in cost reduction,**increased business from outside of Canada, job creation and enhanced Canadian economy, while also aiding**Canada's competitiveness in advanced electroplating technology.
