Hi, I’m Laila Kaira, a researcher at FAMU-FSU College of Engineering. My project focuses on characterizing the mechanical and tribological properties of titanium-hafnium nitride (TiHfN) coatings deposited by plasma-enhanced atomic layer deposition (PE-ALD). Using wear tests with a 3mm ruby ball under nitrogen environments, I evaluate wear rates, delamination, and fatigue resistance to determine suitability for extreme environments. This work aims to improve coatings for applications such as hydrogen storage, microelectromechanical systems (MEMS), and biosensors. Future work includes testing additional compositions, adjusting PE-ALD parameters, and evaluating coating performance under different aging conditions.
