One of the most effective means of increasing automotive fuel efficiency and thereby decreasing greenhouse gas and other harmful emissions is vehicle weight reduction. This can be accomplished through the increased use of advanced high strength steels for structural components and body closures. The use of these materials permit the use of thinner sheet steel cross-sections while maintaining or enhancing passenger safety. However, reducing sheet metal thickness demands enhanced corrosion protection to maintain the structural integrity and meet consumer durability expectations. The continuous galvanizing process is the most cost-effective and widely practiced means of achieving this objective. Advanced steels use higher amounts of alloying elements which make galvanizing difficult as they form oxides, causing the bare spots and other coating defects. However, this is not always the case in practice. The renewal term of the IRC will focus on the interactions of the continuous galvanizing process atmosphere and bath with alloys in the complex and technologically important manganese-silicon series of alloys to develop comprehensive models of the interactions between these surfaces with the objective of developing alloy development guidelines such that both the required mechanical properties can be met while ensuring that the steels can be successfully galvanized. We will also study the newer generation of zinc-based aluminium-magnesium coatings and their interactions with advanced steel surfaces. This term of the IRC will train a total of eleven students for Canadian industry and will provide the steel industry with a set of tools which can be used to maintain and increase their competitive advantage in the highly competitive steel industry.

提高汽车燃料效率并从而降低温室的最有效手段之一 气体和其他有害排放是减轻车辆的重量。这可以通过增加来实现 使用先进的高强度钢作为结构组件和身体封闭。这些材料的使用 在维护或增强乘客安全性的同时，允许使用薄板钢横截面。然而， 减少钣金厚度需要增强腐蚀保护以维持结构完整性和 满足消费者耐用性期望。连续的镀锌过程是最具成本效益的， 实现这一目标的广泛实践手段。 高级钢使用更高量的合金元素，这使得它们在形成时变得困难 氧化物，导致裸露的斑点和其他涂层缺陷。但是，实际上并不总是这样。这 IRC的更新项将集中于连续镀锌过程大气和 与合金浴中的浴中，在复杂且技术上重要的锰 - 硅质系列合金系列中开发 这些表面之间相互作用的全面模型，目的是开发合金 开发准则，可以满足两种所需的机械性能，同时确保 钢可以成功镀锌。我们还将研究基于锌的新一代 铝制涂料及其与晚期钢表面的相互作用。这个IRC这个术语将 总共培训11名学生的加拿大行业，并将为钢铁行业提供一套工具 可以用来维持和提高其在竞争激烈的钢铁中的竞争优势 行业。
