项目摘要
Abrasive wear and corrosion of equipment and consumables have a very large impact on Canadian industry. There is a strong market demand for welding electrodes for iron-based alloy overlays that can resist both abrasive wear and corrosion. Our long-term goal is to better understand the welding metallurgy for wear and corrosion resistant overlays. The objective in this application is to efficiently design a new self-shielding, high-Cr, metal-cored welding wire for overlay that is resistant to wear and corrosion. The technical objectives of the project are to study and control the weld microstructure so that the overlay will meet the requirements: (a) the wear resistance measured by ASTM standard is 0.19g max, and (b) the corrosion resistance measured by ASTM standard is no worse than that of the conventional chromium carbide overlay plates. This proposed research and training project will apply a systematic metallurgical approach to the critical industrial need for cost effective overlay to counter both wear and corrosion. The experimental core for this project involves accelerated alloy selection and wire design and microstructure characterization at University of Alberta, wire fabrication at a SSAB associated facility, and wear and corrosion testing of experimental overlay at a commercial lab. The industrial sponsor, SSAB, has made its R&D and production systems available for this project. The physical metallurgy lab at the University of Alberta has specialized equipment for measuring phase transformations in steels, mechanical properties, metallography, crystal structures, and electron microscopy. The experimental tasks will be performed within a theoretical framework of interactions between chemical composition, process parameters, phase transformations, crack resistance, hardness, and corrosion resistance. The outcome of this project will directly benefit the industrial partner SSAB through the establishment of chemical composition, process windows, and providing the currently unavailable overlay wire for their business.
设备和消耗品的磨损和腐蚀对加拿大工业有很大的影响。对于用于铁基合金覆层的焊接电极存在强烈的市场需求,所述焊接电极可以抵抗磨料磨损和腐蚀。我们的长期目标是更好地了解耐磨和耐腐蚀堆焊层的焊接冶金学。本申请的目的是有效地设计一种新的自保护、高铬、金属芯焊丝,用于耐磨和耐腐蚀的堆焊。本项目的技术目标是研究和控制焊缝显微组织,使堆焊层满足以下要求:(a)按ASTM标准测得的耐磨性最大为0.19 g;(B)按ASTM标准测得的耐腐蚀性不低于传统的碳化铬堆焊板。这个拟议的研究和培训项目将采用系统的冶金方法来满足关键的工业需求,即成本效益高的堆焊层,以对抗磨损和腐蚀。该项目的实验核心包括在阿尔伯塔大学进行的加速合金选择和线材设计以及微观结构表征,在SSAB相关设施进行的线材制造,以及在商业实验室进行的实验覆盖层的磨损和腐蚀测试。工业赞助商SSAB为该项目提供了其研发和生产系统。阿尔伯塔大学的物理冶金实验室拥有专门的设备,用于测量钢的相变、机械性能、金相学、晶体结构和电子显微镜。实验任务将在化学成分,工艺参数,相变,抗裂性,硬度和耐腐蚀性之间相互作用的理论框架内进行。该项目的成果将通过建立化学成分、工艺窗口以及为其业务提供目前不可用的覆盖线,使工业合作伙伴SSAB直接受益。
