Morphological Investigation of Al-Cu-Fe Quasi-Crystalline Thin Film on Ti-۶Al-۴V Alloy

Magnetron sputtering was used in the current study to deposit the quasicrystal (QC) coating on the Ti-۶Al-۴V alloy. After the sputtering process, a continuous argon flow at ۷۰۰°C was used for two hours to anneal the Al-Cu-Fe coated samples. The microstructure and morphology of mixed powders and Al-Cu-Fe QC coatings were examined using scanning electron microscope (SEM) analysis and X-ray diffraction (XRD). The Al۶۲.۵Cu۲۵Fe۱۲.۵ powder mixing was used as the target of the magnetic sputtering process. Al-Cu-Fe thin layer's deposition on the Ti-۶Al-۴V alloy surface took place with no cracks and a thickness of approximately ۴۰۰۰ nm. As shown by calculations, five facet shapes had a size of nearly ۶۴۳ nm. The XRD patterns confirmed the presence of Al۳Fe, AlTi۲, and Al۶۵Cu۲۰Fe۱۵ phases after the post-heat treatment coating.
