摘要

Abstract

Cold spraying technology has a number of unique characteristics,most notably the solid-state metal powder deposition.This property confers the technology with significant technical advantages and application potentials in the domains of coating preparation,high-efficiency and high-speed repair,and additive manufacturing.Nevertheless,when applying for high-strength nickel-based superalloy materials,this technology remains confronted with significant technical challenges,including high coating porosity,inadequate strength,and an absence of plasticity.In this paper,the critical deposition conditions and influencing factors of cold-sprayed superalloys are systematically reviewed,focusing on the microstructure characteristics of deposited materials and their correlations with properties(especially tensile properties),and summarizing the main methods of microstructure and performance optimization,such as post-spray heat treatment,post-spray hot isostatic pressing,laser-assisted cold spraying,and in-situ shot peening-assisted cold spray deposition.In the future,for expanding the engineering applications of cold-sprayed high-temperature alloys,it is necessary to modify the particle deformation conditions and expand the deposition window,to develop the hybrid treatment methods to improve the coating property,as well as lowering the process costs.These measures will provide a theoretical basis and technical guidance for its applications in the fields of aerospace.
