Study of the Removal of Jet Engine Coatings by Water Jet Technology

这个项目是因为喷气发动机使用几年后，由于性能恶化，需要从喷气发动机上去除涂层。这种涂层已经通过传统的研磨或化学浴去除，这些技术既耗时又不环保。水射流工艺提供了一种快速、有效和经济的工艺，只需使用普通水。该项目的主要目标是开发一个数学模型，预测四喷嘴旋转喷嘴的路径和深度。此外，将进行研究，以优化喷气发动机涂层剥离工艺参数，而不破坏基板，考虑表面完整性和材料去除机制。最后，将在一个真实的应用中演示该技术

This project arises from the necessity to remove the coating from the jet engine after a few years of use as their properties get deteriorated. This coating has been removed by traditional milling or chemical baths, techniques that are time consuming and not environmentally friendly. The Water Jet process offers a fast, effective and economical process just using plain water.The main objectives of this project will be to develop a mathematical model that will predict the path and depth of a four-jet swivel nozzle. Moreover, a study will be done to optimize the parameters of jet engine coating striping process without damaging the substrate, considering the surface integrity and material removal mechanisms. Finally, the technology will be demonstrated in a real application
