Surface Treatments of Advanced Parts Made by Additive Manufacturing

增材制造颠覆了现代制造业；这个蓬勃发展的行业使工程师能够以以前无法想象的方式设计功能部件。利用增材制造逐层加工的零件可以合并内部通道和复杂的几何形状。然而，在某些情况下，后期处理，以实现特定的表面光洁度和尺寸精度是将增材制造零件交付到规格的关键。当零件具有复杂设计的通道，没有视线时，这是不可能的。FZ工程公司是一家魁北克初创公司，他们利用了这一特定的工业需求；他们拥有6项专利的增材制造零件后处理技术，将打印的部件转化为适用的，尺寸完美的，表面处理的部件。下一代增材制造组件将采用微结构控制。这种从多晶纹理的转变，为组件提供了增强的机械和腐蚀性能，允许为越来越苛刻的应用生产组件。当采用FZ工程的专利工艺处理时，这种溶解行为的变化将导致表面不可预测的变化和随之而来的材料去除。因此，本提案的目的是用3种不同的合金生产这样的微结构控制部件，并将它们整合到FZ工程的表面处理工艺中。具体来说，材料去除率和表面变化将被表征，并集成到FZ的预测模型中；以获得对这些特殊零件的常规加工的稳健迭代。AM的设计自由与具有新微结构的零件相结合，有可能进一步颠覆这个行业，这项工作的交付将使FZ在这个不断发展的行业中进一步扩大竞争优势。

Additive manufacturing has disrupted modern manufacturing; this booming industry is enabling engineers to design functional components in previously unimagined ways. Parts utilizing the layer-by-layer processing of AM can incorporate internal channels and complex geometries. However, in some circumstances, post processing, to achieve specific surface finishes and dimensional accuracy are key in delivering AM parts to specification. This can be impossible when parts have channels with complex designs, without line of sight. FZ Engineering are a Quebec Startup who have capitalized on this specific industrial need; they have 6 patented post-processing technologies for AM produced parts, transforming printed components to application ready, dimensionally perfect, surface treated components.The next generation of AM components will be microstructure-controlled. This shift, from polycryalline textures, gives components enhanced mechanical and corrosion performance allowing the production of components for more and more demanding applications. This change in dissolution behavior will result in unpredicted changes at the surface and consequent material removal when processed by FZ Engineering's Patented Processes. Therefore, the aim of this proposal is to produce such microstructure-controlled components from 3 different alloys, and integrate them into FZ Engineering's surface finishing process. Specifically, the rate of material removal, and surface changes will be characterized, and integrated into FZ's predictive model; to obtain a robust iteration of their conventional processing for these specialist parts. The merging of AM's design freedoms in tandem to parts with new microstructures, has the potential to further disrupt this industry the delivery of this work will enable FZ to further grow their competitive advantages in this ever growing industry.
