Definitions
- the invention relates to a heat treatment to improve the oxidation resistance in chromium-containing steels, which are used at low temperatures, a component and Ver drive to operate a turbine.
- the object is achieved by a method according to claim 1, a component according to claim 3 and a method according to claim 4.
- the preferably degreased and cleaned components are pre-oxidized in a heat treatment in the temperature range from 873K to 923K + - 10K in an atmospheric furnace (electrically or gas-heated with excess air).
- the pre-oxidation can also take place in controlled atmospheres, for example in process gases with an increased oxygen content;
- the components can be treated in preparation for the preoxidation process with a blasting process (sandblasting, shot peening, etc.) that improves the preoxidation effect by providing diffusion paths in the form of dislocations.
- a blasting process sandblasting, shot peening, etc.
- FIG. 1 shows the procedure or the use according to the prior art
- FIG. 2 contains the procedure according to the invention.
- Figure 1 shows a substrate 4 'made of a chromium-containing steel, which is used directly in operation at temperatures from 673K to 823K.
- an oxidation layer 7 ' is formed on the surface 23' from a lower chromium-rich iron oxide layer 10 'and an outer iron oxide layer 13'. This leads to flaking 16 '.
- the substrate 4 is pre-oxidized at a temperature higher than in use, i.e. here preferably> 873K. During this heat treatment, a pure chromium oxide layer 20 is formed, so that there is no flaking during later operation at 673K to 823K.
