| Abstract: |
| As a high-temperature chemical surface treatment process steam treatment aims to generate an oxide protective film with strong combination, high hardness and density, so as to improve the properties of materials, such as corrosion and wear resistance, air tightness and surface hardness and so on. It features with low-cost, high dimensional precision, solid combination between oxide layer with substrate, aesthetic appearance and environment-friendly. Ordinary carbon steel was steam treated in a self-designed steam boiler. Combination strengLh, thickness, composition and related characteristics of surface oxide film were studied by scratch testing, X-ray, SEM and other means. The results show that the average thickness of the film is lOμm, exceeding 8μm obtained by blackening treatment, and the combination between the film and the substrate is stronger than the one obtained by traditional blackening treatment. Moreover, in the same circumstances, the critical load of the steam treated oxide film decreases with the increasement of the holding time, and the density becomes poor compared with the film obtained by blackening treatment. |
