| Abstract Scope |
This research explores mechanochemistry to create functional surface treatments. A planetary centrifugal mixer was used to modify BAM particles (aluminum magnesium boride, Al3Mg3B56) and fluorite (CaF2) surfaces. Native BAM particles do not flow easily, inhibiting their use for additive manufacturing; therefore, organic surface treatments are explored to create better flowability. (3-Aminoproply)triethoxysilane was used to create a more hydrophilic BAM surface. Fluorite particles were treated with oleic acid to increase hydrophobicity, and to aid in mineral beneficiation. Both systems were evaluated using Fourier-transform infrared spectroscopy and contact angle goniometry to determine the effectiveness of mixing and surface reactivity. After treatment BAM has shown improved flowability, and the fluorite became more hydrophobic. Mechanochemical processing has proven successful in transforming surface properties, and holds promise for surface engineering in areas of additive manufacturing and mineral processing. |
