本文介绍了一种水射流装置对聚合物-颗粒涂层系统的冲蚀研究。两个已建立的磨损模型的修改版本被应用到这个系统，这些是基于一个简单的硬度控制的磨损模型和体积韧性控制的磨损模型。涂层的机械性能进行了修改，其体积性能的特点是使用压痕硬度技术。采用水射流试验装置研究了相同涂层的水动力冲蚀特性。涂层的侵蚀进行了定性观察，也被量化的临界水射流压力。修改后的磨损模型，然后应用到这个系统中，在涂层的体积力学性能，和模型进行了严格的评估和评价。
This paper describes a study of the erosion of a polymer-particle coating system by a water jet apparatus. Modified versions of two established wear models were applied to this system; these were based on a simple hardness controlled abrasion model and a bulk toughness controlled abrasion model. The mechanical properties of the coatings were modified and their bulk properties were characterized using an indentation hardness technique. The hydrodynamic erosion characteristics of the same coatings were examined using a water jet apparatus. The erosion of the coatings was observed qualitatively and was also quantified in terms of a critical water jet pressure. The modified wear models were then applied to this system, in terms of the bulk mechanical properties of the coatings, and the models were critically evaluated and appraised.
