A method for preparing a bactericidal film having a titanium carbonitride carrier layer on metal comprising preprocessing, polishing, plating a bactericidal film carrier layer and a bactericidal film. The surface of the polished metal is smooth. During the plating process, as silver ions do not react with carbon and nitrogen, through changing the number of carbon and nitrogen atoms, various desired colors of the bactericidal film may be achieved. Subsequently, a nano silver sputtering target is initiated, which enables silver ions with bactericidal effect to be uniformly distributed in the titanium carbonitride film layer, thus forming a colored bactericidal film with bactericidal effect. The workpiece is hung on the hanging rack during the plating process, which allows the rotation and revolution of the workpiece to be simultaneously achieved, thus realizing a uniform plating during the target's sputtering while avoiding damage to the workpiece due to local high temperature.

In the present invention, film forming performed under reduced pressure conditions on the surface of a grain-oriented electromagnetic steel sheet which is passed through the inside of a film forming chamber after finish-annealing. A plurality of stages of inlet-side reduced pressure chambers arranged on the inlet side of the film forming chamber have an internal pressure which becomes closer to the internal pressure of the film forming chamber as the inlet side reduced pressure chambers approach the film forming chamber. A plurality of stages of outlet-side reduced pressure chambers arranged on the outlet side of the film forming chamber save an internal pressure which becomes closer to atmospheric pressure as the outlet-side reduced pressure chambers are distanced from the film forming chamber. The inlet-side reduced pressure chambers and the outlet-side reduced pressure chambers comprise: partition plates which define each reduced pressure chamber and in which are formed a sheet-passing hole having a shape through which the grain-oriented electromagnetic steel sheet can pass; and sealing pads arranged on the upper and lower sides of the sheet-passing hole in the partition plates. Due to this configuration, harm to the grain-oriented electromagnetic steel sheet after finish-annealing is suppressed.

A housing for an electronic device can include a metallic component at least partially defining an external surface of the device. The metallic component can have an average grain size less than 45 nanometers in a first region that extends from the external surface to a depth of at least 100 microns below the external surface, and an average grain size greater than 45 nanometers in a second region adjacent to the first surface.

A method and a vacuum-coating system (10) for coating a strip-shaped material (11), in particular made of metal, are disclosed. Thereby, the strip-shaped material (11) is moved over a conveying section (12) in a transport direction (T) and vacuum-coated within a coating chamber (14) in which a vacuum is applied. When viewed in the transport direction (T) of the strip-shaped material (11), at least one trimming shear (38) is arranged upstream of the coating chamber (14), with which the strip-shaped material (11) is trimmed at at least one strip edge, preferably at both strip edges, in order to produce a constant width for the strip-shaped material (11) over its longitudinal extension.
