In this paper, Raman spectral mappings were carried out on Vickers indentation prints introduced on DLC films prepared with different substrate bias voltages (SBV). The mapping results showed clear differences in the intensity ratio, ID/IG, and band

Diamond-like carbon films/coatings (DLC) can be employed in a wide range of applications, but the film quality and performance are strongly dependent on the deposition conditions. In this paper, we attempted to clarify the structural and compositiona

Thin-film metallic glasses (TFMGs) are an optimal material for nanoimprint technology. In this study, we prepared Ti–Cu–Zr–Ni–Hf–Si TFMG films by Ar ion bombardment using unbalanced magnetron sputtering (UBMS) and investigated the effect of

The effects of the size and volume fraction of the precipitated crystalline phase induced by friction stir processing (FSP) on the hardness in Zr–Al–Ni–Cu bulk metallic glass (BMG) was examined. The microstructure in the friction zone (FZ) exhi
