| Abstract: |
| In order to give the appearance of the metal surface and improve the surface finish and cleanliness, reinforce metal corrosion resistance, by means of the interface reactions of nickel plate surface, insoluble coordination compound films were formed with a metallic luster of various colors changing in accordance with the reaction time. The films are functional finishing layers , possessing not only decorative properties, but also improving the brightness and clealiness of the metal surface. The results of the photoelectron spectrometer ( XPS and AES) analyses show that the thicknesses of the films are about 300, 175, 80 and 120 nm. Mo existed as +6, +4 in the film, and P existed as +5. The elemental compositions in golden-yellow film were caculated on the AES depth profile curves : M0 26. 60-/o ,P 11. 80-/o , Na 5. 30-/o , 0 56. 3 0-10 . |
