Title: Surface treatment method and apparatus for metallic material
Inventor: NINOMIYA SUSUMU
IPC: C23C22/78
Filed: 2001-10-16
Abstract: PROBLEM TO BE SOLVED: To form a thin, strong layer excellent in rust prevention and corrosion resistance on the surface of a metallic material. SOLUTION: After immersed in liquid sodium 8, a metallic material M with the liquid sodium 8 adhered to the surface thereof is immersed in a reaction liquid 15 (e.g. water). By this step, sodium adhered to the surface of the material M reacts with water to be alkalinized, instantly producing sodium hydroxide and thus forming a passive film on the surface (texture) of the material M. The passive film is chemically very stable and can keep the corrosion of the material M very little.
