| titleOfInvention | Tin-free steel having superior seam weldability and its manufacture |
| abstract | PURPOSE: To improve the weldability of a tin-free steel (TFS-CT) obtd. by forming a two-layered film consisting of a metallic chromium layer and a chromium oxide hydrate layer on the surface of a steel sheet by depositing projections in the metallic chromium layer by a prescribed method. n CONSTITUTION: A steel sheet is cathodically electrolyzed in an electrolytic chromating bath to form metallic chromium and chromium oxide hydrate on the surface of the steel sheet. This steel sheet is washed, dried and electrolytically chromated again. Thus, TFS-CT having 30W500mg/m 2 metallic chromium layer contg. deposited projections of chromium and 5W20mg/m 2 chromium oxide hydrate layer is obtd. The relative-specular glossiness at 20° of the TFS-CT is a prescribed value after the upper chromium oxide hydrate layer is dissolved in hot alkali. n COPYRIGHT: (C)1987,JPO&Japio |
