This thesis research investigates the surface properties and performances of gold
nanoparticles, microarc oxidation coating, and epitaxial nano-twinned copper film. The
research aims to understand the critical behavior of material surfaces in order to facilitate
design and development of new materials for tribological applications. The research will
focus on improving of the gun barrel performances. Experimental approaches will be
used for combining analysis with basic thermal energy transfer principles. Results
obtained here will be used for developing new materials to be used in facilitating gun
barrels.
Experimental approach includes scanning calorimetry-thremogravimetric
analysis, tribological testing, and potentiodynamic polarization.
The fundamental understanding obtained here will be beneficial for the gun
barrel design, manufacturing, and military technologies followed by the results of
experiments with different three types of materials.
The results of this research showed that the coatings with microarc oxidation and
nano-twinned structure improved wear resistance from the tribological examinations and
size of AuNPs affected their thermal behaviors measured by differential scanning
calorimetry and thermogravimetric analysis method.
