Definitions

  • the present invention relates to an armoring part for a vehicle.
  • Vehicles with special protection are used to protect persons and valuables from bullets released from handguns and long guns (ballistic protection).
  • Such vehicles are conceived to prevent penetration of bullets coming from all directions.
  • armoring parts are installed in the vehicles, e.g. in side panels including body sills with A-, B-, C-, (D-) pillars and doors, front and rear parts, roof area, and floor assembly.
  • an armoring part for a vehicle includes a steel plate made of at least partially hot formed and press hardened armor steel and having a hardness of 380 to 760 Vickers (HV), and a coat applied on at least one side of the steel plate and made of a metal material which is softer than a metal material of the armor steel, the coat being a thermally applied layer and having a hardness of 10 to 230 Vickers (HV).
  • An armoring part for a vehicle in accordance with the present invention is of reduced thickness and lighter weight, compared to a conventional armoring part for a vehicle, while still maintaining superior ballistic properties.
  • the present invention resolves prior art problems by combining a steel plate of armor steel with high hardness and strength with a coat of softer metal material compared to the metal material of the armor steel. Tests have shown that superior ballistic properties could be realized with both hard-core projectiles and soft-core projectiles bullets.
  • the coat is applied upon the steel plate on the outer side of the armoring part.
  • an armoring part for a vehicle in accordance with the present invention has at least the same resistance and bombardment classifications as a conventional armoring of same type without coat, while the wall thickness of the steel plate of armor steel can be reduced between 10% and 35%, typically by 20% in an armoring part according to the present invention.
  • the reduction in wall thickness is a weight saving. This has a positive effect on special protective vehicles in terms of economy and ecology.
  • the coat can be joined to the steel plate by a form fit and/or force fit.
  • the coat is a thermally applied layer that can be sprayed onto the steel plate.
  • a thermally applied layer can be produced by coating with a material that is in a solid, grainy, or powdery state.
  • Coating involves thermal spray techniques, e.g. flame spraying, arc spraying, or plasma spraying processes.
  • the coat can be made of aluminum or an aluminum alloy.
  • An example of an aluminum alloy is Al99.5.
  • the coat can be made of zinc or a zinc alloy.
  • the steel plate can have a thickness of 5.0 mm to 10.0 mm, in particular a thickness of 7.0 mm to 9.5 mm.
  • a thickness of the steel plate of 7.3 mm to 8.4 mm.
  • the coat can have a thickness of 0.01 mm to 0.4 mm, in particular a thickness of 0.025 mm to 0.25 mm.
  • a thickness of the coat of 0.05 mm to 0.2 mm.
  • the armoring part for a vehicle has a three-dimensional shape. Shape and geometry can be best suited to the use of the armoring part in a vehicle.
  • the steel plate of an armoring part for a vehicle in accordance with the present invention is at least partially hot formed and press hardened.
  • Currently preferred is a complete hot forming and press hardening of the steel plate.
  • the used armor steel may undergo heat treatment with subsequent quench hardening.
  • the armoring part for a vehicle may be provided with a cathodic coat of dipping varnish.
  • the application of the cathodic coat of dipping varnish is advantageously realized after the vehicle has been manufactured and/or after manufacturing the vehicle with further components, such as armor components.
  • the armor steel can be made of a steel alloy which contains at least the following alloying components, expressed in weight-%:
  • the steel allow may contain the further alloy components, expressed in weight-%:
  • An armoring part for a vehicle which includes an armor steel made from the afore-described steel alloy in combination with a coat in accordance with the present invention exhibits superior properties in terms of resistance to penetration, even when subjected to multiple attacks with projectiles, or in terms of bullet resistance. Armor steel can now be used with lesser wall thickness because of the combination with the coat, while still being in compliance with demanded resistance and bombardment classifications.
  • the steel plate can have a hardness of 380 to 760 Vickers (HV).
  • HV Vickers
  • the steel plate can have a hardness in a range from 475 to 665 Vickers (HV).
  • HV Currently preferred is a hardness of the steel plate of 520 to 620.
