Abstract
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). Applied on at least one side of the steel plate is a coat which is made of a metal material which is softer than a metal material of the armor steel. The coat is a thermally applied layer and has a hardness of 10 to 230 Vickers (HV).
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A three-dimensionally formed armoring part for a vehicle, comprising:
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, said coat being a thermally applied layer and having a hardness of 10 to 230 Vickers (HV).
2 . The armoring part of claim 1 , wherein the coat is joined to the steel plate by a form fit and/or force fit.
3 . The armoring part of claim 1 , wherein the coat is made of aluminum or an aluminum alloy.
4 . The armoring part of claim 3 , wherein the aluminum alloy is Al99.5.
5 . The armoring part of claim 1 , wherein the coat is made of zinc or a zinc alloy.
6 . The armoring part of claim 1 , wherein the steel plate has a thickness of 5.0 mm to 10.0 mm.
7 . The armoring part of claim 1 , wherein the steel plate has a thickness of 7.0 mm to 9.5 mm.
8 . The armoring part of claim 1 , wherein the steel plate has a thickness of 7.3 mm to 8.4 mm.
9 . The armoring part of claim 1 , wherein the coat has a thickness of 0.01 mm to 0.4 mm.
10 . The armoring part of claim 1 , wherein the coat has a thickness of 0.025 mm to 0.25 mm.
11 . The armoring part of claim 1 , wherein the coat has a thickness of 0.05 mm to 0.2 mm.
12 . The armoring part of claim 1 , further comprising a cathodic coat of dipping varnish.
13 . The armoring part of claim 1 , wherein the armor steel is made of a steel alloy which contains at least the following alloying components, expressed in weight-%:
Carbon (C)
0.2-0.5
Manganese (Mn)
0.3-2.5
Nickel (Ni)
0.5-3.0,
and further alloy components, remainder iron (Fe) and impurities resulting from smelting.
14 . The armoring part for a vehicle of claim 13 , wherein the further alloy components include, expressed in weight-%:
Silicon (Si)
0.1-0.3
Phosphor (P)
<0.05
Sulphur (S)
<0.02
Aluminum (Al)
<0.08
Copper (Cu)
<0.12
Molybdenum (Mo)
0.1-1.0
Boron (B)
0.001-0.01
Nitrogen (N)
<0.05
Chromium (Cr)
0.1-1.0
Titanium (Ti)
<0.1
Cobalt (Co)
<2.0
Niobium (Nb)
<0.08.
15 . The armoring part for a vehicle of claim 1 , wherein the steel plate has a hardness of 475 to 665 Vickers (HV).
16 . The armoring part for a vehicle of claim 1 , wherein the steel plate has a hardness of 520 to 620 Vickers (HV).
17 . The armoring part for a vehicle of claim 1 , wherein the coat has a hardness of 15 to 115 Vickers (HV).
18 . The armoring part for a vehicle of claim 1 , wherein the coat has a hardness of 20 to 100 Vickers (HV).Join the waitlist — get patent alerts
