| Abstract Scope |
Dry Aerosol Deposition (DAD) is an emerging technique for depositing dense ceramic coatings
at room temperature without requiring post-treatment. In this study, natural aluminosilicate
mineral is used as a low cost feedstock with DAD to enhance the surface mechanical properties
of low carbon steel and add corrosion-erosion protection. Process parameters were optimized to
produce coatings with thicknesses on the order of 10 microns that exhibit strong adhesion and
uniform coverage. Comprehensive characterization was performed using profilometry, atomic
force microscopy and scanning electron microscopy to evaluate surface roughness,
microstructure and coating integrity. A nano-micro-mechanical system was used for nano-
indentation and scratch testing to show how DAD coatings effectively improve surface hardness
while preserving the elasticity of the substrate. This talk will describe how parameters such as
substrate surface roughness affect coating quality and performance. Preliminary corrosion
experiments via electrochemical impedance spectroscopy will also be presented. |
