Research Progress of Low Damage Machining Technology for SiCp/Al Composites

摘要:

SiCp/Al复合材料具有优异的性能，在尖端的空天装备中应用广泛，但由于其组成相碳化硅颗粒和铝合金之间存在的巨大性能差异，使得加工过程中极易出现加工损伤，严重影响SiCp/Al复合材料产品的精度和使役性能，制约着SiCp/Al复合材料的工程化应用。本文围绕SiCp/Al复合材料低损伤加工技术，从加工损伤的形成机理、加工损伤的影响因素、低损伤加工工具和加工工艺三个方面对国内外相关的研究进展进行分析，总结目前针对SiCp/Al复合材料低损伤加工技术研究现状和不足之处，并指出发展趋势和方向。

Abstract:

SiCp/Al composites have excellent properties and are widely used in advanced aerospace equipment. However, due to the great difference in physical and mechanical properties between SiC particles and aluminum alloy, it is easy to be damaged in the process of processing, which seriously affects the accuracy and service performance of SiCp/Al composites products and restricts its engineering application. This paper focuses on the low damage processing technology of SiCp/Al composites, analyzes the related research progress at home and abroad from three aspects: the formation mechanism of processing damage, the influencing factors of processing damage, low damage processing tools and low damage processing technology, summarizes the current research status and shortcomings of low damage processing technology for SiCp/Al composites, and brings forward the development trend and direction.
