Abstract

Aerosol deposition is a feasible method of fabricating dense ceramic films at room
temperature by the impact consolidation of submicron‐sized particles on ceramic,
metal, glass, and polymer substrates at a rapid rate. Despite the potential usefulness
of the aerosol deposition process, there are issues, such as deposition mechanisms
and structure of the film‐substrate interface, that are not well understood. We have
used complementary structural and microstructural analysis to capture the state of the
substrate surface after the aerosol deposition process. The results reveal that modification
of the substrate surface by the ejected submicron‐sized particles is essential
for the formation of anchoring layer, thereby, a change in internal residual stress
state and surface free energy of the substrate is required to deposit film using AD
process. Our analysis also suggests that the adhesion between the metal substrate and
ceramic particles is possibly contributed by both physical bonding and mechanical
interlocking.
