| Abstract Scope |
Ni<sub>1-x</sub>Co<sub>x</sub> leading edge guards have been shown to reduce the degradation rate of propellers and rotor blades in sandy environments. While this legacy alloy has been successfully used to protect the core material, an alloy of a wide multi-element composition space could potentially outperform the binary. 100+ ternary compositions of CoNiCr and CoNiV have been fabricated via arc melting to begin mapping out the space of erosion-resistant alloys. Microhardness measurements and their standard deviations provided an initial method to screen out alloys with intermetallic phases and served as an initial surrogate model for erosion resistance. Currently, a custom automated sandblaster allows higher-fidelity screening of samples and more direct erosion measurements, while Bayesian optimization supports future alloy design extensions and testing efficiency. Results, difficulties, and correlations between measurements will all be discussed, alongside considerations for the integration of new alloys with existing systems. |
