Heat and mass transfer phenomena in the application of wired-based nickel/tungsten carbide overlays

这项研究和培训项目的重点是开发一种新技术，以创造用于油砂作业、采矿、伐木和重型设备制造的耐磨金属表面。现有技术可以采用镍基与碳化钨硬质颗粒相结合的强化材料来获得合适的性能；然而，现有的技术既缓慢又昂贵。该项目将首次以系统、科学的方式研究现有焊接技术（气体金属电弧焊）的延伸，以创建保护性的镍/碳化钨涂层。该方法将涉及阿尔伯塔大学现有的实验能力，这在世界上是独一无二的。理论工作和数学建模，以及金相和磨损测试也将进行。所获得的结果将立即用于合作公司（Syncrude），并将广泛适用于其他公司和行业。此建议将涉及一名硕士学生和四名本科生的培训。

This research and training project focuses on developing a new technology to create wear-resistant metallic surfaces used in operations of oil sands, mining, logging, and manufacturing of heavy equipment. Existing technologies can obtain appropriate performance using a combination of nickel matrix and tungsten carbide hard particles as reinforcement; however, existing technologies are slow and expensive. This project will study for the first time in a systematic, scientific way the extension of an existing welding technology (Gas Metal Arc Welding) to create a protective nickel/tungsten carbide coating. The approach will involve an experimental capability available at the University of Alberta and that is unique in the world. Theoretical work and mathematical modeling, as well as metallography and wear testing will also be performed. The results obtained will be of immediate use to the partner company (Syncrude) and will have a broad applicability to other companies and industries. This proposal will involve the training of one MS student and four undergraduate students.
