The bonding of metallic alloys and composite materials in the form of a hybrid structure is a line of great interest for the current industry. The different machinability of both materials requires a specific machining process. Abrasive water-jet machining (AWJM) is an excellent technology for the simultaneous machining of both materials. However, defects at the micro and macro-geometric level have been detected in several scientific articles. In this review, a detailed study of the two main defects in metals, composite materials and hybrid structures has been developed. The conclusions of several scientific articles have been exposed for a better understanding of the topic in articles between 1984 and 2020. The influence of the cutting parameters on the reduction in kinetic energy of the water jet and the order of stacking of the materials in the hybrid structure is the main objective in order to minimize these defects. Cutting parameter optimization studies, predictive model proposals, process-associated defects and evaluation methodologies have been discussed. The aim of this article is to set a solid background on AWJM machining in hybrid structures and on the influence of cutting parameters on generated defects and machining strategies to obtain the best results at a macro and micro-geometric level.

金属-碳纤维杂化材料的磨料水射流加工研究进展

以混合结构形式结合金属合金和复合材料是当前工业界非常感兴趣的一条生产线。两种材料的可加工性不同，需要特定的加工过程。磨料水射流加工（AWJM）是同时加工两种材料的一项出色技术。但是，在几篇科学文章中已经检测到微观和宏观几何层面的缺陷。在这篇综述中，已经对金属，复合材料和混合结构中的两个主要缺陷进行了详细研究。为了更好地理解1984年至2020年之间的文章中的主题，公开了几篇科学文章的结论。切削参数对水射流动能的降低以及混合结构中材料堆叠顺序的影响是主要目的，目的是使这些缺陷最小化。已经讨论了切削参数优化研究，预测模型建议，与过程相关的缺陷和评估方法。本文的目的是为混合结构中的AWJM加工以及切削参数对产生的缺陷和加工策略的影响奠定坚实的背景，以便在宏观和微观几何水平上获得最佳结果。
