Surface engineering processes are used to produce functional coatings. They require surface preparation steps to remove surface contaminants and impart physical anchoring points promoting coating mechanical adhesion to a substrate. VLN Advanced Technologies manufactures customized water jet devices for industry specific applications. To broaden its current market, VLN has recently explored the possibility of modifying its patented pulse water jet (PWJ) technology to enable its use as a green surface preparation method. While these studies have clearly demonstrated the potential of the technology, it has been deemed important by VLN to develop a robust fundamental knowledge of the process physics to allow designing and optimizing a commercially suitable PWJ system for surface preparation. This proposal aims to elucidate the process physics through modeling and experimental validation of the various process parts.

表面工程工艺用于生产功能性涂层。它们需要表面处理步骤来去除表面污染物，并赋予物理固定点，以促进涂层与基材的机械附着力。VLN先进技术公司为行业特定应用定制水射流设备。为了扩大目前的市场，VLN最近探索了修改其专利脉冲水射流（PWJ）技术的可能性，使其成为一种绿色表面制备方法。虽然这些研究已经清楚地证明了该技术的潜力，但VLN认为重要的是要发展强大的过程物理基础知识，以便设计和优化商业上适合表面制备的PWJ系统。本方案旨在通过对各工艺部分的建模和实验验证来阐明工艺物理。
