Morphology, composition and crystallography are three common objects for microanalysis in material science. The developments of 3D techniques in material microanalysis facilitate researchers to explore in 3D space. 3D chemical analysis is of important in 3D microanalysis family but need to be improved and promoted. Combining 2D imaging in lateral with sputtering in depth, layered SIMS imaging can be reconstructed in 3D. Detailed 3D-SIMS analysis of interfaces between phases, such as concentration change and inhomogeneity of diffused species near interface, provide diffusion information between coating and substrate with new view. Such 3D-SIMS technique become a useful and popular tool to generate full-view images in 3D space for various specimens with layered or complex structure from inorganic, organic and biological research. It provides a wealth of composition information and gives deep insights that cannot easily be attained in other interfacial analysis.

Normal approach in 3D-SIMS can display the species in layered or complex structure. However, detailed analysis of interfaces between phases, such as concentration change and inhomogeneity of diffused species near interface, attract more attention that need to be explored. For example, diffused interface is expected to be a sign of solid bonding for the safety of coating service life. New 3D imaging approach is developed to separate the diffused species through the interface. In terms of the ion imaging of CsAl+ in diffusion region, diffused Al at the interface between the ceramic coating and Zircaloy substrate were investigated in both as-deposited and annealed states.

The new analytics toolkit to resolve diffused species is a key evaluation to develop coating layer on alloys. The new method based on 3D-SIMS analytics is expected to provide diffusion information between coating and substrate with new view. It will continue to advance and gives more information about the formation of diffusion interface which facilitate the interface analysis from variety of research interest.
