Surface Treatments of Advanced Parts Made by Additive Manufacturing

加法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想象不到的方式设计功能部件。利用AM的逐层加工的零件可以结合内部通道和复杂的几何形状。然而，在某些情况下，后处理，以实现特定的表面光洁度和尺寸精度是交付AM零件达到规格的关键。当零件具有设计复杂且没有视线的通道时，这是不可能的。FZ Engineering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项获得专利的后处理技术，用于AM生产的部件，将印刷部件转换为可应用的、尺寸完美的表面处理部件。下一代AM部件将是微观结构可控的。这种由多晶织构转变而来的转变，增强了零部件的机械性能和耐腐蚀性，使其能够为越来越苛刻的应用生产零部件。这种溶解行为的改变将导致表面发生意想不到的变化，并在使用FZ Engineering的专利工艺处理时去除材料。因此，这项计划的目标是从3种不同的合金中生产这种组织可控的部件，并将它们集成到FZ Engineering的表面精加工过程中。具体地说，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；以获得针对这些专业部件的传统工艺的稳健迭代。AM的设计自由与具有新微结构的部件的融合，有可能进一步颠覆这个行业。这项工作的交付将使FZ在这个不断增长的行业中进一步增强竞争优势。

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.
