Definitions
- the invention relates to a cutting edge with a thermally sprayed coating.
- the invention further relates to a method for coating a cutting edge a thermal spray process.
- Thermal spray processes are essentially characterized by the fact that they are in usually evenly applied coatings of high quality and quality enable. Coatings applied by thermal spraying can by varying the spray materials and / or the process parameters to different Requirements are adjusted. The spray materials can always be processed in the form of wires, rods or powder. It post-treatment may also be provided.
- thermal spraying as a general coating process are as process variants basically autogenous flame spraying or high-speed flame spraying, arc spraying, plasma spraying, detonation spraying and known as laser spraying.
- HVOF High Velocity Oxygen Fuel
- At least one side of the cutting edge is included in the production of the coating Spray materials containing hard materials coated. This is done today using First or second generation high speed flame spraying, i.e. With average spray particle speeds below 450 m / s, or by means of plasma spraying.
- the coating of sharp edges proves to be problematic.
- the applied Layers adhere poorly, loosen or stand out at the edges and therefore break out.
- the breaking out on the edge can also be a result of relatively brittle coating occur.
- the susceptibility to corrosion is also problematic the cutting, supported by cleaning the knives.
- the object of the present invention is therefore to provide a cutting edge and a method of to point out the type mentioned at the beginning, by which the service life is made possible or to increase the service life of the coated cutting edge.
- the cutting edge at least partially includes a coating that has compressive stresses.
- the cutting edge coated according to the invention preferably comprises a coating, that extends to the cutting edge of the cutting edge.
- Coatings with compressive stresses can be produced by the coating by means of a thermal spray process with medium spray particle speeds is applied over 450 m / s.
- the high-speed flame spraying of the third is therefore suitable for the invention and fourth generation with average spray particle speeds over 450 m / s.
- Third and fourth generation systems of high speed flame spraying, with which the required speeds can be reached known for example under the names "DJ 2600", “DJ 2700” and "JP 5000".
- the cutting edge can also advantageously be coated by means of cold gas spraying getting produced.
- Coatings of the cutting edges can therefore, for example, by means of high-speed flame spraying with the mentioned systems from Sulzer Metco "DJ 2600 “or” DJ 2700 “, which work with propylene, hydrogen or ethene fuel gases, or the TAFA system "JP 5000", which works with liquid fuel gases like kerosene, getting produced.
- cermets metal-bound Carbides
- WCoCr titanium-bound Carbides
- the cutting edges can be produced using thermal spraying processes in particular powders with particle sizes from 1 ⁇ m to 1 mm, particularly preferably with 5 to 100 ⁇ m.
- the coating is advantageous at medium spray particle speeds over 550 m / s, preferably over 600 m / s, particularly preferably applied between 600 and 700 m / s.
- higher particle speeds ensures that this with the Solidification of the material associated with shrinkage on the substrate and the resulting shrinkage Tensile stresses due to the beam effect with high kinetic energy impacting particles is overcompensated.
- the coating preferably has compressive stresses of up to 600 MPa between 50 and 550 MPa. Compressive stresses in the named areas can be used with the systems of the third and fourth generation of high-speed flame spraying devices easily manufacture.
