摘要:
The present invention is an invention relating to the technique of forming an inorganic film which realizes an inorganic film excellent in durability and of the low cost, making the previous wax or polymer processing unnecessary. The apparatus of the present invention consists of a charged water producing tank 1, a magnetic field treating tank 2 and a film forming tank 3. The charged water producing tank 1 is provided with a raw water supplying port 11, a charged water b taking out port 12, and a ceramic particle-filled part 13 in which an infinite number of ceramic particles 14 containing at least silicon and aluminum as a dissolving out component are filled therein. The magnetic field treating tank 2 is provided with a charged water feeding port 21 and a magnetic field-treated water c taking out port 22, in which an S poll 23a and an N poll 23b for forming an electromagnetic field are arranged, and the tank has a passage water path 24 for passage of charged water b therebetween. The film forming tank 3 is provided with a magnetic field-treated water c feeding port 31 and a treated waste water d taking out port 32, and is provided with a nozzle 34 for spraying pressurized magnetic field-treated water c to a surface of a work 33 arranged in the tank.
