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.

提高汽车燃油效率从而减少温室气体排放的最有效方法之一 气体等有害排放物是减轻车辆重量的。这可以通过增加 使用先进的高强度钢制造结构部件和阀体封闭件。这些材料的使用 允许使用较薄的钢板横截面，同时保持或提高乘客安全。然而， 减小板材厚度需要加强防腐保护，以保持结构完整性和 满足消费者对耐用性的期望。连续镀锌工艺是最具成本效益和 广泛采用的实现这一目标的手段。 先进钢使用更多的合金化元素，这使得它们在形成时很难镀锌 氧化物，造成裸露斑点和其他涂层缺陷。然而，在实践中并不总是这样。这个 IRC的续期将侧重于连续镀锌工艺气氛和 在复杂的和具有重要技术意义的锰硅系列合金中用合金来开发 这些表面之间相互作用的综合模型，以开发合金为目标 开发指南，以便既能满足所需的机械性能，又能确保 钢可以成功地镀锌。我们还将研究新一代的锌基 铝镁涂层及其与先进钢表面的相互作用。IRC的这一任期将 为加拿大工业共培养11名学生，将为钢铁行业提供一套工具 可以用来保持和增加他们在竞争激烈的钢材中的竞争优势 工业。
