Definitions

  • the invention relates to a thermo-kinetically deposited cermetic layer or such a layer composite for or as ballistic protection systems.
  • the thermally sprayed support layer has the task of breaking projectiles, especially those with hard metal character but also others.
  • the ballistic protection system itself comprises a base material and / or a substrate on which the cermetic layer and / or the cermetic layer composite is applied as a ballistic protective layer or as a ballistic-acting protection by high-speed flame spraying (HVOF, HVOLF).
  • HVOF high-speed flame spraying
  • liquid fuels are also preferred.
  • this protective structure When exposed to a protective structure with a projectile or with splinters, this protective structure experiences essentially a strong punctual load.
  • the protective structure assumes the task of reducing this burden and to prevent the impinging bullet from further penetration or penetration.
  • the ceramic breaks the bullet or eroded, while a so-called liner material, eg. As aramid or elastomers or other tough materials that stops or retains remaining fragments.
  • Another ballistic protection concept or protection module describes the DE 10 2009 043 492 B4 , Here, a ceramic tile and its support are tightly enclosed by a shrink tube, creating a compressive stress, the local ballistic Weaknesses in such ceramic composites prevented.
  • a protective device against projectile-forming charges shows the DE 10 2009 040 305 B4 on.
  • the protective device consists of strips of material consisting of different materials. These are superimposed lying facing the direction of action as a sandwich.
  • the DE 10 2008 028 318 A1 discloses a bullet-resistant transparent laminate.
  • the protective device after the DE 10 2010 054 568 A1 protects especially against multi-missiles.
  • metal and / or ceramic body are doped.
  • the invention has the object to show a ballistic-acting protection system that is easy to manufacture, projectiles and the like can break and is characterized by a low weight.
  • the invention is based on the idea to use thermo-kinetically deposited cermetic layers or laminates as a ballistic or ballistic-acting protective layer on (on) a base material.
  • Cermets for their part, are composites of ceramic materials in a metallic matrix binder phase and are characterized by particularly high hardness and wear resistance.
  • the thermally sprayed overlay layer has and accomplishes the task of breaking the projectiles, for example those with carbide character but also with a soft core (for example, lead, iron, etc.), and the like.
  • Special hard-material layers are used which, among other things, have very high hardnesses.
  • thermo-kinetically applied layer systems or layer composites of cermetic materials can be applied to very dense layers on the different substrate materials.
  • the spraying of the layer (s) allows the use of robotic burners.
  • the use of robot-guided burners in turn allows the coating of complex three-dimensional component structures and curved surfaces.
  • a method for applying a metallic corrosion protective layer of self-adhering but non-self-fluxing powders such as cermets, etc. by means of flame spraying discloses DE 35 15 314 A1 , Before the protective layer is sprayed onto the base material, a self-fluxing, corrosion-resistant metal powder is cold-sprayed on. This corrosion-resistant metal powder creates the corrosion protection layer.
  • a device for producing a hard metal or cermet mixture describes the DE 20 2007 012 740 U1 ,
  • HVOF High Velocity Oxygen Fuel
  • burners with extremely high kinetic energy of the supersonic fast hot particle jet.
  • gaseous fuels such as e.g. Propane, propene or acetylene operated.
  • a special coating method is used as a special variant of the HVOF process group for the ballistic protective layers described here, in which additionally a liquid fuel, eg kerosene, is used as energy carrier (HVOLF burner).
  • HVOLF burner a liquid fuel, eg kerosene
  • the HVOLF process is used to process the cermets (ceramic hard material particles in metallic matrix), such as Cr 3 C 2 / NiCr and WC / Co.
  • the group of ultra-hard WC / co-materials can be processed very well with the process, since the thermal load of the powder can be kept low.
  • liquid fuel increases the energy density in the combustion chamber and, above all, the kinetic energy of the particle-laden hot gas jet without the gas temperature increase. In this case, speeds of the powder particles of up to 1000 m / s are achieved. These high particle velocities lead to very dense, homogeneous layers with low porosity and at the same time high adhesion to the substrate. In addition to the high hardness, the layers have high corrosion resistance and wear resistance. Due to the intense heat and mass transfer in the coating process as well as the (extremely) high kinetic impact, process- and cooling-induced residual stresses develop in the laminate, which are used to advantage in a targeted process.
  • the HVOLF process permits a high material throughput, ie a high production output, which makes the process particularly suitable for large-area coatings and for producing high layer thicknesses.
  • a high material throughput ie a high production output
  • the use of intelligent robot systems and controls with optimized trajectories enables the coating of partially complex shaped components and curved open spaces.
  • the layers used preferably consist of the highest possible proportion of ceramic hard material powder and a small proportion of metallic or refractory metallic binder phase, from which just one or the desired hard-tough layer composite results as a support layer.
  • Such a layer composition in combination with a high hardness, a good adhesion and a high compression bias forms a combination of the protective layer function for breaking the projectiles.
  • manufacturing technology the ability to complex component geometries, such as corners, radii, edges, fillets, etc., reliably, evenly and reproducibly coat.
  • Fig. 1 is a simplified protection system 1, comprising at least one base material or substrate 3, on which a cermetic layer or a cermetic layer composite 2 is sprayed. Even the cermetic layer can form the ballistic protective layer.
  • Fig. 2 shows by way of example applied to the substrate 3 layer material 2 in an enlarged view.
  • Fig. 3 indicates a simplified illustrated device 10 for coating the substrate 3 at. 11
  • a HVOF burner or HVOLF burner
  • HVOF burner injects molten particles 12 - cermetic materials - onto the substrate 3, which then solidify into a layer 2 on the surface 4 (interface) of the substrate 3.
  • the layer 2 was slightly separated from the substrate 3.
  • the layer 2 is directly or via adhesion support on or on the substrate 3) but also known coolant incl. circulation / integration in the burner 11th
  • the substrate 3 (material) and the layer material 2 should preferably be matched to one another become.
  • the substrate material is steel
  • the layer material should be applied in a different thickness than other substrate materials.
  • the process parameters for a thicker layer and a lighter substrate 3 are used differently than for thin layers and a denser material.
  • the cermetic layer or the layer composite 2 may be a proportion of hard material phase in% by weight of, for example, 60-98, the remainder being binder phase (particle 12).
  • the hard material phase can consist inter alia of a carbide, such as tungsten carbide, chromium carbide, titanium carbide, tantalum carbide, niobium carbide, vanadium carbide, silicon carbide, etc., as well as mixtures of these.
  • a carbide such as tungsten carbide, chromium carbide, titanium carbide, tantalum carbide, niobium carbide, vanadium carbide, silicon carbide, etc., as well as mixtures of these.
  • Co Cobalt
  • CoCr CoCr30W12C2.5 (STELLITE), CoNi32Cr21Al8Y0.5, CoMo28Cr18 (TRIBALOY)
  • nickel (Ni) or nickel alloys as well as iron (Fe) or iron alloys can also be used as the binder phase.
  • a so-called adhesive layer can be provided, but this is not necessarily a condition.
  • e.g. NiCr, NiAl and the like are used as such an adhesive layer.
  • This layer then serves to better adhere the protective layer 2 to the base material 3, that is, the layer increases the adhesion of the cermetic layer 2 to the base material 3.
  • the thickness of this primer layer applied to the base material 3 may be in a range of max. a few hundred micrometers, but can also, as already mentioned, be omitted.
  • the surface of the base material 3 may be untreated. If a pretreatment is desired, the surface can be pretreated, for example, by sandblasting, water jetting, machining, erosion, laser ablation and / or laser processing, etc. This measure causes an additional roughening of the surface and generally serves to promote the micromechanical clamping of the layers.
  • the thermally applied layer can be sprayed directly onto the structure to be protected.
  • a protection system 1 or such protective systems 1 (not shown in detail) on the object to be protected, releasably secured, for example screwed or the like.
  • a combination of the two possibilities extends the field of application or the individual adaptation of the ballistic protection to the requirements or conditions.
  • the objects / vehicles etc. to be protected can be adapted to the individual protection requirements and, in the case of a subsequent connection of the protection systems 1, also on site. Due to the lower weight of the protection system 1 also requirements for various transport conditions can be met.
