Abstract
Protective barrier includes a soft metal that inhibits or delays thermal or grinding attack tool penetration. The soft metal, which may be disposed between other layers and otherwise delays thermal attack by expanding or “puffing” during attack. The soft metal can inhibit mechanical attack by rapid ablation and wear of a cutting wheel or blade. The protective barrier may additionally include an oxide or carbide layer.
Claims15
A barrier system, comprising:
- a substrate;
- and
- a barrier layer applied to and coated upon the substrate;
- an additional barrier layer between and in contact with the substrate and the barrier layer, wherein the additional layer is formed of an additional barrier material selected from a group consisting of carbides and oxides;
- and
- an outer layer covering the barrier layer, the outer layer selected from a group consisting of metals, ceramics, paints, polymers and epoxies;
- wherein the barrier layer comprises a metal;
- and
- wherein the metal is selected from a group consisting of zinc, lead, tin, aluminum, gallium, thallium, indium, antimony, bismuth and copper.
A container for securing an item, comprising:
- an enclosure at least partially defining an interior space;
- wherein the enclosure includes a barrier system, the barrier system comprising:
- a substrate;
- and
- a barrier layer applied to and coated upon the substrate;
- an additional barrier layer between and in contact with the substrate and the barrier layer, wherein the additional layer is formed of an additional barrier material selected from a group consisting of carbides and oxides;
- and
- an outer layer covering the barrier layer, the outer layer selected from a group consisting of metals, ceramics, paints, polymers and epoxies;
- wherein the barrier layer comprises a metal;
- and
- wherein the metal is selected from a group consisting of zinc, lead, tin, aluminum, gallium, thallium, indium, antimony, bismuth and copper.
A method of forming a protective enclosure, comprising:
- disposing a barrier system between an object and a point of entry to the object, the barrier system comprising:
- a substrate;
- and
- a barrier layer applied to and coated upon the substrate;
- an additional barrier layer between and in contact with the substrate and the barrier layer, wherein the additional layer is formed of an additional barrier material selected from a group consisting of carbides and oxides;
- and
- an outer layer covering the barrier layer, the outer layer selected from a group consisting of metals, ceramics, paints, polymers and epoxies;
- wherein the barrier layer comprises a metal;
- and
- wherein the metal is selected from a group consisting of zinc, lead, tin, aluminum, gallium, thallium, indium, antimony, bismuth and copper.
