Corrosion Behaviors of Li-B-H Films in Air

Abstract:

In the present study, Li-B-H films contained LiBH₄ and Li₂B₁₂H₁₂ were fabricated under different hydrogen pressures (20, 70 Pa) at ambient temperature by pulsed laser deposition (PLD). The corrosion behaviors of the films were studied over a time of 1-24 h in the air at ambient temperature. Fourier transform infrared spectrometry (FT-IR), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) were used to analyze the formed oxidation film. The results indicated that an oxidation film with obvious cracks and holes were formed, which was composed by Li₂B₄O₇ and Li₂CO₃. The films were mainly reacted with H₂O and CO₂, so the oxidation of Li-B-H could be prevented by avoiding exposed to air.
