利用电子背散射衍射技术研究了Al2O3基体上冷喷涂铝涂层的显微组织演变。从动态回复和动态再结晶的角度讨论了粉末纯度和基体加热对喷涂态和退火态涂层中晶粒平均取向差和小角度晶界分布的影响。
Electron backscatter diffraction is used to study the microstructural evolution of cold‐spray aluminum coatings on Al2O3 substrates. The influence of powder purity and substrate heating on the kernel average misorientation and the distribution of low‐angle grain boundaries in as‐sprayed and annealed coatings are discussed in terms of dynamic recovery and dynamic recrystallization.
