Abstract Plain Waterjet (PW) technology is an ideal process to remove damaged multi-layer coatings efficiently without damaging the substrate material. This paper proposes a mathematical model that calculates the jet footprint to remove multi-material coatings using a rotational multiple plain water jet nozzle accurately, with the new approach of considering the wear resistance properties of each material layer to provide a high efficiency coating removal. It has been proven that this enables controlled multi-layer aerospace coating removal avoiding alteration (i.e. erosion) of the substrate for both flat and curved target surfaces leaving them free of any coating residuals.

用于控制去除多材料涂层的旋转式多水射流建模

摘要 普通水射流（PW）技术是一种有效去除损坏的多层涂层而不损坏基材的理想工艺。本文提出了一种数学模型，该模型使用旋转式多水射流喷嘴准确计算去除多材料涂层的射流足迹，并采用新方法考虑每个材料层的耐磨性，以提供高效的涂层去除。已经证明，这可以实现受控的多层航空航天涂层去除，避免平面和弯曲目标表面的基材发生变化（即侵蚀），使它们没有任何涂层残留物。
