Ultrathin films of Al2O3, TiO2, ZnO, HfO2, and ZrO2 were deposited on copper metal using ALD, and their corrosion protection properties were measured using electrochemical impedance spectroscopy (EIS) and linear sweep voltammetry (LSV). Analysis of ∼50 nm thick films of each metal oxide demonstrated low electrochemical porosity and provided enhanced corrosion protection from aqueous NaCl solution. The surface pretreatment and roughness was found to affect the extent of the corrosion protection. Films of Al2O3 or HfO2 provided the highest level of initial corrosion protection, but films of HfO2 exhibited the best coating quality after extended exposure. This is the first reported instance of using ultrathin films of HfO2 or ZrO2 produced with ALD for corrosion protection, and both are promising materials for corrosion protection.}, number={4}, journal={ACS APPLIED MATERIALS & INTERFACES}, author={Daubert, James S. and Hill, Grant T. and Gotsch, Hannah N. and Gremaud, Antoine P. and Ovental, Jennifer S. and Williams, Philip S. and Oldham, Christopher J. and Parsons, Gregory N.}, year={2017}, month={Feb}, pages={4192–4201} }

The coatings separate the metal substrate from the coolant, preventing corrosion and erosion. This is addressing issues in remote or mobile environments where high quality coolant fluids are not available. Previous research demonstrated the effectiveness of alumina and hafnia nanoscale coatings. The current research is investigating additional materials and the optimum thickness and application processes. A prototype application system is being assembled to test with deliverable products. The presentation will describe the latest test results, describe the applications system, and provide the schedule for the program.}, booktitle={2017 eighteenth international vacuum electronics conference (ivec)}, author={Ives, R.
