Multi-Scale Computational Design and Synthesis of Protective Smart Coatings for Refractory Metal Alloys


Performer: University of Wisconsin System

Project No: FE0007377


Accomplishments


Niobium samples were coated with different ratios of Si-B and Mo-Si-B before undergoing oxidation testing. The presence of Nb2O5 was identified in the mixed oxides of samples at all ratios. Given the same Si:B ratios, the Mo-Si-B coating imparted enhanced oxidation protection to the Nb samples compared to the samples coated with Si-B only. These empirical results, along with computer modeling results, will be used to develop and test new refractory alloy coatings with the goal of increasing their useful operating temperatures.
