In this Phase I STTR program, the project team will develop a mathematical model for the hydrogen permeation inhibiting efficiency for various metals and alloys. Experiments based on the Devanathan-Stachurski method will be used to determine the models kinetic parameters, which control hydrogen permeation. The hydrogen entry efficiency and effectiveness of electrodeposited, nanostructured layers of several coatings, such as Ni-P, Ni-B, Ni-P-X, Ni-B-X (X=WC, SiC etc.) composites, that inhibit hydrogen permeation into the hard metals and alloys will also be evaluated. In Phase II, the model will be used to optimize the coating surface properties to a level that essentially stops hydrogen absorption. Furthermore, the model will be developed into a user-friendly interface and, eventually, a software package for use by Air Force engineers to apply for specific aerospace-use materials and conditions. Commercialization activities and economic analyses throughout this program will meet the needs of the first customer, the U. S. Department of Defense, followed by expansion of the technology to meet the needs of third-party clients. BENEFIT: The anticipated result of the proposed STTR program is the development and validation of a hydrogen permeation model based on empirical data collected from Devanathan-Stachurski experimentation. The initial customer for this program is the Department of Defense; government investment in this project is crucial at this stage to the viability of developing coatings that prevent hydrogen permeation and corrosion in aerospace applications. This model will initially be packaged as a user-friendly interface for engineers of the U. S. Air Force. Upon successful demonstration, the model can be available for commercial metallurgical and metal finishing industries, where the model can be used to quantify the hydrogen entry efficiency in their manufacturing and development processes. )
