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既涉及增强的空气动力学设计和高级材料的使用。该项目着重于高级材料及其耐用性，但也可以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，我们将研究将用于风隧道测试的3D打印机。这些零件通常会因“机库皮疹”而受到损害，因为正常处理，与伊斯克面相关的损坏。为了克服这一点，这些零件将用薄金属涂层进行电镀。将进行一系列测试和表征，以评估几个辅助涂层在其粘结强度，抗刮擦性和表面表面表面特征方面的有效性。 。这项研究的影响将提高用于风口测试的3D打印结构的耐用性，从而节省成本和较小的环境影响。其次，这项研究将使3D印刷零件所需的表面工程有益，这些零件最终可以在RealaeroSspace应用程序中使用。
