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.

Burloak Technologies是精密工程组件和支持服务的供应商。它最近创建了一个世界领先的增材制造工厂，该设施的重点是太空领域的组成部分。 在太空行业中，热等静止压力（HIP）是用于铸造和添加剂（AM）组件的重要后制过程。在臀部期间，金属保持在高温和压力下，以消除内部孔隙度并改善材料特性。空间行业目前正在使用针对低性能铸件建立的相同基本的髋关节过程和控制定义。对于高度关键和高性能的AM硬件，这些实践远非最佳。这限制了AM为空间行业所做的创新。 Burloak将很快在其Oakville设施中完成加拿大唯一的商业髋关节船。 该联盟提案的目的是在Burloak和McMaster之间建立合作伙伴关系，以开发“以空间为中心”的髋关节工艺规范，重点介绍了该空间行业的两种战略合金； AL10SIMG和TI-6AL-4V。 拟议的工作将确定根据上述材料成分制造的组件的最佳时间温度压力循环。 它还将利用Burloak最先进的髋关节船舶的气体淬火能力，以开发更有效的治疗方法，涉及更少的处理步骤。 拟议的工作将追求专门设计的新AL合金的开发，以利用AM工艺和Burloak Hip船只的特定功能。 这将使Burloak消除几个昂贵的热处理步骤。 拟议的工作将巩固Burloak在AM在空间行业的地位。 它还将填补加拿大太空组件供应链中的关键空白。 目前，缺乏本地设施和有关髋关节的专业知识，导致所有加拿大空间组件都用于海外进行处理。 这对与太空相关的受控货物构成了安全风险，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行业的发展。 它还将在这个关键和不断扩展的部门中训练3 HQP。
