Tribological behavior of the kinetic sprayed Ni_(59)Ti_(16)Zr_(20)Si_2Sn_3 bulk metallic glass

摘要

Gas atomized amorphous Ni_(59)Ti_(16)Zr_(20)Si_2Sn_3 feedstock particles were fed into warm gas dynamics and they were successfully overlaid onto the mild steel substrate. Through the X-ray diffractometry and differential scanning calorimetry, it could be confirmed that thermally activated processes such as crystallization and in-flight particle oxidation were effectively suppressed during the modified kinetic spraying process. In order to evaluate the tribological behavior of the kinetic sprayed Ni_(59)Ti_(16)Zr_(20)Si_2Sn_3 BMG coating, a partially crystallized coating and a fully crystallized coating were prepared by isothermal heat treatments.
