Abstract:
1. A method of forming an antibacterial film on a surface of an object, the method comprising: configuring both a cathode target source and a magnetron sputtering target source within a vacuum chamber; installing at least one of a zirconium target, a titanium target and a chromium target onto the cathode target source; installing a silver target onto the magnetron sputtering target source; filling the vacuum chamber with argon and nitrogen so as to respectively ionize the silver target and one of the zirconium target, the titanium target and the chromium target; remotely controlling an ionization proportions between one of the zirconium target, the titanium target and the silver target in the proportions of: zirconium nitride:silver=90-99%:1-9%, titanium nitride:silver=90-99%:1-9%, chromium nitride:silver=90-99%:1-9%; and forming on the surface of the object a film selected from one of zirconium nitride-silver film, titanium nitride-silver film and chromium-silver film.
