| Abstract Scope |
The high-power impulse magnetron sputtering (HiPIMS) generates high-density plasma through higher instantaneous pulse currents, resulting in thin films with fewer defects, higher density, and better crystallinity. In this experiment, a combination of HiPIMS and radio frequency (RF) power sputtering system was used to deposit TiZrNbSiMo high-entropy alloy thin films with varying titanium content on 316 stainless steel substrates. The composition of thin films were analyzed using electron Probe Microanalyzer (EPMA). Subsequently, potentiodynamic polarization corrosion tests were conducted on the high-entropy alloy thin films in Ringer's solution using a potentiostat to evaluate their corrosion resistance. The biocompatibility of the thin films was verified using MG63 cells. This study found that the corrosion resistance of TiZrNbSiMo high-entropy alloy thin films can reach 18 times that of 316 stainless steel, and they also possess excellent biocompatibility. Therefore, TiZrNbSiMo high-entropy alloy thin films have high potential for applications in the field of biomedical implants. |
