Abstract
The present invention relates to a composite liner for a shaped charge device. The liner comprises a wrought metal or metal alloy substrate having a desired shape and configuration and a coating deposited on a surface of the wrought substrate. The coating comprises a substantially uniform, substantially homogeneous isotropic material having a relatively fine grain structure and a relatively smooth surface which facilitates forming a metal jet having improved performance and penetration.
Claims22
A liner having a desired shape and a desired thickness for use in a shaped charge device, said liner comprising:
- a first layer formed from a wrought metal or metal alloy;
- and
- a coating deposited on a surface of said first layer, said deposited coating comprising a substantially uniform, substantially homogeneous isotropic material having a relatively fine grain structure.
A shaped charge device comprising:
- a casing;
- a shaped explosive charge within said casing, said charge having a cavity formed in a first end;
- a liner having a desired shape lining said cavity and contacting said charge;
- said liner being formed from a composite material comprising a wrought metal or metal alloy substrate having a first surface contacting said charge and a relatively thin coating deposited onto a second surface of said substrate opposed to said first surface;
- and
- said deposited coating comprising a substantially uniform, substantially homogenous isotropic material having a relatively fine grain structure.
A process for forming a composite shaped charge liner, said process comprising:
- forming a substrate having a desired shape and thickness from a wrought metal or metal alloy;
- immersing said substrate in an electrolytic bath;
- and
- electrolytically forming a coating comprising a substantially uniform, substantially homogeneous isotropic material having a relatively fine grain structure on a surface of said substrate.
