  • Production method for forming an antibacterial film on the surface of an object
    Patent number: 8968529
    Abstract: A production method combining cathode arc and magnetron sputtering methods to form an antibacterial film on the surface of an object. Inside the vacuum chamber, both a cathode arc target source and a magnetron sputtering target source are configured. On the cathode arc target source, at least one of a zirconium, titanium, or chromium target is installed. On the magnetron sputtering target source, a silver target is installed. Argon and nitrogen are filled into the vacuum chamber to respectively ionize the silver target and one of the zirconium target, titanium target, or chromium target. Remote control is used to adjust the ionization proportion between one of the zirconium, titanium, or chromium target and the silver target to be 90-99%:1-9%. The surface of the object is formed with one of the zirconium nitride-silver mixed antibacterial film, titanium nitride-silver mixed antibacterial film, or chromium nitride-silver mixed antibacterial film.
