The invention relates to a preparation method for multicolor oxide film, comprising that an anode oxide film forming step is repeatedly carried out. The anode oxide film forming step comprises: oxidizing color anode, and forming a protective layer and laser carving on a color anode oxide film. The color anode oxidation comprises anode oxidation, dyeing and hole sealing are carried out in turn on the surface of a base material so as to obtain a color anode oxide film. The protective layer is used for separating electrolyte oxidized by a color anode and a color anode oxide film formed previously. The laser carving is used for removing at least one part of color anode oxide film formed previously so as to cause the surface of parts of base material to be exposed. The integral corrosion resistance and abrasion resistance of the oxide film on the surface of the base material, which is prepared according to the method of the invention, are high, and no other macromolecule materials need to be coated, so that the texture of the oxide film is kept.

The liquid to be atomized is uniformly sprayed on the inner surface of a hollow rotating cylinder, for example by means of one- or two-fluid-nozzles and is thus distributed on bores provided in the cylinder wall. The rotation of the cylinder causes the liquid to flow outwards through the bores. Droplets are generated when the liquid flows out of the bores by laminary decomposition of the jet. The flow rate in each bore lies in the range 1.0<+E,dot V+EE B (a3 rho 5/ sigma 5)0.25<16 to prevent the droplets from becoming too large and to satisfy the condition of an adequate flow laminarity, i.e. for the value of the Reynolds number for the continuous liquid flow in the boress not to exceed Re delta 400. +E,dot V+EE B represents the flow rate of the liquid in each bore, a represents the centrifugal acceleration at the outer surface of the cylinder, rho represents the density of the liquid and delta indicates the surface tension of the liquid. The large number N>200 of bores having the diameter DB in the cylinder wall causes the flow rate of liquid through each bore to be relatively low, so that a continuous laminary flow in each bore is ensured even at low viscosities and technically useful total flow rates. Preferably cylindrical bores with a minimum length at least three times larger than the bore diameter are provided in the cylinder wall, with a narrow spacing in the range defined by 1.1<t/DB<5, so that a number of bores as large as possible may be arranged in the wall of the cylinder.
