METHOD AND DEVICE FOR JOINT OXYDATION AND HEAT TREATMENT OF WORKPIECES |
| 摘要 |
Disclosed is a method for joint oxydation and heat treatment of workpieces at temperatures </=1300 DEG in the treatment chamber of an oven containing a neutral or reactive gas in a temperature range above 570 DEG . In order for the process to be reproducible and to produce homogeneous oxide layers, the PH2O/PH2 ratio is adjusted after transformation of the workpiece structure such as found at the ambient temperature into the structure wanted during the heat treatment in such a way that the line FeO + H2 =Fe + H2O is exceeded and an oxide layer is formed from FeO < 10 mu m. |
