Innovative breakthroughs in enabling technologies can revolutionize the Albertan and Canadian landscape, bringing permanent developmental change. Technological advances and innovation apply across a broad spectrum of industrial activities to drive radical change in industry capabilities. Investments in the oil & gas sector will increase over the next 5 years. The aerospace sector is expected to grow over the same period, demanding innovation through research and technology development. Industry and government emphasize the need for novel materials development and manufacturing to keep pace with growth. They also stress urgency in connecting state-of-the-art digital and autonomous technologies to drive radical change and improve infrastructure lifetimes. Our proposed research will tackle these challenges by contributing new high-strength reinforced metal matrix composite materials and nanograin-stabilized high entropy alloys in an additive manufacturing repair paradigm using an autonomous mobile system. It will be built on the multifaceted hybridization of cold spraying and friction stir processing to fabricate wrought material repairs with high strength, structurally and functionally integrated into the repaired structure to ensure longevity. This will be accomplished for extreme environments that are unsuitable or inaccessible for human work using autonomous mobile systems integrated with surface assessment, monitoring, and navigation systems. Use of remote sensing, data communication systems, and machine learning to improve integration of autonomous system dynamics into sensor network architectures will produce state-of-the-art research outcomes for autonomy of high-payload additive manufacturing and materials processing systems hybridized for in field repairs with augmented sensing capability. In line with Alberta's advanced materials & manufacturing technologies and information and communications technologies target areas, outcomes of this project will underpin a paradigm shift in new materials development and autonomous fabrication and processing. This will make substantive contributions to place Canada and Alberta as global leaders in surface engineering, repair, and manufacturing.

使能技术的创新突破可以彻底改变阿尔伯塔省和加拿大的景观，带来永久性的发展变化。技术进步和创新应用于广泛的工业活动，推动工业能力的根本变化。未来5年，石油和天然气行业的投资将会增加。航空航天领域预计将在同一时期增长，这需要通过研究和技术开发进行创新。工业和政府都强调需要新材料的开发和制造来跟上增长的步伐。他们还强调，迫切需要将最先进的数字技术和自主技术结合起来，以推动根本性变革，提高基础设施的使用寿命。我们提出的研究将通过使用自主移动系统在增材制造修复范例中提供新的高强度增强金属基复合材料和纳米颗粒稳定的高熵合金来解决这些挑战。它将建立在冷喷涂和搅拌摩擦加工多方面杂交的基础上，制造高强度的锻压材料修复，使其在结构和功能上与修复结构融为一体，确保使用寿命。这将在不适合或无法进入人类工作的极端环境中完成，使用集成了地面评估、监测和导航系统的自主移动系统。利用遥感、数据通信系统和机器学习来改善自主系统动力学与传感器网络架构的集成，将为高载荷增材制造和材料处理系统的自主性提供最先进的研究成果，这些系统将与增强的传感能力相结合，用于现场维修。根据艾伯塔省先进材料和制造技术以及信息和通信技术的目标领域，该项目的成果将支持新材料开发和自主制造和加工的范式转变。这将为加拿大和艾伯塔省在表面工程、维修和制造方面的全球领先地位做出实质性贡献。
