Recent advances in aerospace engineering involve both enhanced aerodynamic design and use of advancedmaterials. This project focuses on advanced materials and their durability but also enables use of thesematerials as test structures for validating aerodynamic designs. More specifically, we will study 3D printedparts that will be used for wind tunnel testing. These parts are often damaged from 'hangar rash' that issurface-related damage from normal handling. To overcome this, the parts will be electroplated with thinmetallic coatings. An array of testing and characterization will be done to evaluate the effectiveness of a fewcandidate coatings in terms of their bond strength, scratch resistance and surface finish characteristics.Altogether, the project will also examine the effect of process variables on the properties and effectiveness ofthe coatings. The impact of this research will be increased durability of 3D printed structures used for windtunnel testing, leading to cost savings and less environmental impact. Secondly, this research will have benefitof understanding surface engineering required for 3D printed parts that may eventually be used in a realaerospace application.

航空航天工程的最新进展包括改进的空气动力设计和先进材料的使用。该项目专注于先进材料及其耐久性，但也允许将这些材料用作验证空气动力学设计的测试结构。更具体地说，我们将研究用于风洞测试的3D打印部件。这些部件通常是由于“机库皮疹”而损坏的，这是正常操作时与表面相关的损坏。为了克服这一点，这些部件将被电镀上薄金属涂层。将进行一系列测试和表征，以评估几种候选涂层的结合强度、耐刮擦性和表面光洁度的有效性。此外，该项目还将检查工艺变量对涂层性能和有效性的影响。这项研究的影响将是提高用于风洞测试的3D打印结构的耐用性，从而节省成本并减少对环境的影响。其次，这项研究将有助于理解3D打印部件所需的表面工程，这些部件最终可能会用于真实的航空航天应用。
