Definitions
- the invention relates to a method for producing a protective layer on walls of combustion plants, heat exchangers or similar plants, which are exposed to hot gases, in particular flue gases and are loaded in a predetermined temperature range, and in which a plasma spraying process is used a powder of metallic, carbide, oxide ceramic or silicide materials or mixtures of these materials is applied to the previously cleaned, metallic walls to form the protective layer.
- Such protective layers should e.g. be applied to cooling walls of waste heat boilers on steel converters. These walls are exposed to particularly high loads. On one side flow approx. 1 00 ° -
- DE 23 55 532 C2 discloses a method for powder deposition welding of metals and alloys on a preheated metal base prepared by sandblasting, in which the metal liage is previously heated to at least 100 to about 650 ° C.
- the base material is heated very strongly when the protective layer is applied, which leads to an undesirable structural change.
- the melting temperature is between 980 and 1060 ° C, depending on the spray powder used. Due to the high heat input, this also occurs Warping of the walls to be coated. When installing these walls, problems and additional costs may arise due to the dimensional inaccuracies.
- the protective layer has a thickness of approximately 8 to 10 mm for build-up welding and 1 to 2 mm for flame spraying.
- DE-AS 26 30 507 is also a process for the production of
- the present invention has for its object to propose a generic method in which these problems do not occur and in particular the distortion of the workpieces and crack-forming stresses in the base material are avoided.
- the base material of the walls is activated in such a way that disturbances are generated in the metallic lattice, as a result of which the adhesive forces are increased.
- the powder is then applied to the walls under atmospheric conditions after the plasma spraying process, the surface of which thereby maintains approximately room temperature.
- the composition of the powder is determined depending on the existing base material and the later operating conditions, in particular the specified temperature ranges.
- tensile stresses of between 50 and 800 N / mm 2 , preferably between 500 and 800 N / mm 2
- These stress states are calculated by means of the thermal expansion coefficients of the base material on the one hand and of test workpieces made of different powders on the other hand. The mathematical determination can then be checked in accordance with DIN 50121.
- a heat-resistant and shock-resistant protective layer against hot gas corrosion and / or mechanical wear is generated on flat or curved walls of combustion plants, heat exchangers, in particular of waste heat boilers on steel converters.
- an 80 KW plasma spraying device with an internal powder supply has proven to be particularly suitable. It becomes powder with a grain size of less than 75 ⁇ m, preferably 20 to
- the surface of the walls to be treated can be roughened and activated with high-grade corundum, preferably with high-purity white high-grade corundum.
- the surface is only heated to approximately 40 ° C. at most 60 ° C. by the plasma jet and the powder particles melted therein. As a result, warping of the wall surfaces can be excluded in particular.
- a powder containing a Ni alloy is expediently used.
- the stress temperature of the walls treated with a protective layer can be in the range between 300 and 1800 ° C., preferably 600 and 1000 ° C.
- the voltage behavior in the transition zone of the base material and the applied protective layer in the temperature range between 0 and approximately 1200 ° C. is shown as an example in a voltage-temperature diagram. This is based on the measured, average linear thermal expansion coefficients of the two material partners.
- the tensile state slowly builds up again after the stress, ie in the diagram, the drawn line of the stress curve is traversed in the opposite direction.
- the so-called 0 state can naturally also be 400 ° or 800 ° C instead of 700 ° C.
