Hot Isostatic Pressing of Additively Manufactured Space-Use Components in Aluminum and Titanium

Burloak Technologies 是一家精密工程组件和支持服务的供应商。该公司最近创建了一家世界领先的增材制造工厂，专注于航天领域的零部件。 在航天工业中，热等静压 (HIP) 是铸造和增材制造 (AM) 部件的重要后处理操作。在热等静压过程中，金属处于高温高压下，以消除内部孔隙并改善材料性能。航天工业目前正在使用为低性能铸件建立的相同基本 HIP 工艺和控制定义。对于高度关键和高性能的增材制造硬件来说，这些做法远非最佳。这限制了航天工业增材制造的创新可能。 Burloak 很快将在其奥克维尔工厂完成加拿大唯一的商业 HIP 船舶的安装。 该联盟提案的目标是在 Burloak 和 McMaster 之间建立合作伙伴关系，开发“以航天为中心”的 HIP 工艺规范，重点关注航天工业的两种战略合金； Al10SiMg 和 Ti-6Al-4V。 拟议的工作将确定由上述材料增材制造的组件的最佳时间-温度-压力循环。 它还将利用 Burloak 最先进的 HIP 容器的气体淬火能力来开发涉及更少加工步骤的更有效的处理方法。 拟议的工作将致力于开发新型铝合金，这些合金专门设计用于利用增材制造工艺和 Burloak HIP 容器的特定功能。 这将使 Burloak 能够消除几个昂贵的热处理步骤。 拟议的工作将巩固 Burloak 在航天工业增材制造领域的地位。 它还将填补加拿大航天零部件供应链的一个关键空白。 目前，由于当地缺乏 HIP 设施和专业知识，导致加拿大所有航天部件都被运往海外进行加工。 这给与太空相关的受控物品带来了安全风险，并导致成本和交货时间大幅增加。 因此，该提案将有助于加拿大航天工业的发展。 它还将在这个关键且不断扩展的领域培训 3 名总部人员。

Burloak Technologies is a supplier of precision engineered components and support services. It recently created a world leading additive manufacturing facility which is focused on components for the space sector. In the space industry, Hot Isostatic Pressing (HIP) is a vital post-process operation for cast and Additive Manufactured (AM) components. During HIP the metal is held at high temperatures and pressures to eliminate internal porosity and improve the material properties. The space industry is currently using the same basic HIP processes and control definitions established for low performance castings. These practices are far from optimum for highly critical and high-performance AM hardware. This limits the innovation possible with AM for the space industry. Burloak will soon complete installing Canada's only, commercial HIP vessel at its Oakville facility. The goal of this Alliance proposal is to create a partnership between Burloak and McMaster to develop "space-centric" HIP process specifications focusing on two strategic alloys for the space industry; Al10SiMg and Ti-6Al-4V. The proposed work will identify the optimal time-temperature-pressure cycles for components that are additively manufactured out of the above materials. It will also exploit the gas quenching capabilities of the state-of-the-art HIP vessel at Burloak to develop more efficient treatments that involve fewer processing steps. The proposed work will pursue the development of new Al alloys that are specifically designed to take advantage of AM processes and the specific capabilities of the Burloak HIP vessel. This would permit Burloak to eliminate several expensive heat-treatments steps. The proposed work will solidify Burloak's position in AM for the space industry. It will also fill a critical gap in Canada's space component supply chain. Presently, the absence of local facilities and expertise on HIP results in all Canadian space components being shipped overseas for processing. This poses a security risk to space-related controlled goods, as well as, resulting in a substantial increase in cost and lead times. The proposal will, therefore, aid the development of Canada's space industry. It will also train 3 HQP in this critical and expanding sector.
