Cold spraying is a deposition method based on the bonding resulting from severe plastic deformation caused by high-speed impact of materials. It has advantages such as low processing temperature, high deposition speed, and small thermal impact. It has shown great potential in the fields of material additive manufacturing and repair of damaged industrial key components. In recent years, cold spraying hybrid manufacturing technology is an emerging technology, among which laser hybrid cold spraying is becoming an important direction and has received increasing attention. This review aims to review and summarize the research progress of laser hybrid cold spraying technology, with a focus on three composite methods: laser pretreatment, laser synchronous composite, and laser post treatment. Summarize each composite method from three aspects: composite principle, composite advantages, and composite effect, and compare the differences between laser composite cold spraying technology and a single technology in terms of microstructure and performance of the deposition layer. By comprehensively summarizing the recent progress of laser hybrid cold spraying technology, this review will provide guidance and reference for further promoting the research and application of laser hybrid cold spraying technology.
