Abstract
Radiation shield and methods for manufacturing a radiation shield are provided herein, the method includes identifying a substrate for the radiation shield; identifying at least one material for cold spraying on the substrate; applying by cold spray a coating of the at least one material on the substrate thereby obtaining a radiation shield. The radiation shield is lighter, thinner, and more efficient compared to conventional radiation shields.
Claims19
A method for manufacturing a radiation shield, the method comprising:
- identifying a substrate for the radiation shield;
- identifying at least one material including a refractory metal for cold spray deposition on the substrate;
- and
- applying by cold spray deposition a coating of the at least one material on the substrate thereby obtaining a radiation shield.
A radiation shield comprising:
- a substrate having a cold sprayed coating of at least one material,
- the substrate selected from:
- an aluminum alloy, a titanium alloy, a lead alloy, stainless steel, a copper alloy, a brass alloy, and any combination thereof.
A method of forming a radiation shield, the method comprising:
- identifying a refractory metal and an absorbing material having radiation resistance properties;
- propelling a particulate form of the refractory metal onto a substrate at a velocity resulting in adherence of the propelled metal to the substrate to form a refractory layer;
- and
- propelling a particulate form of the absorbing material onto the refractory layer to form an absorbing layer, the refractory layer and absorbing layer having a complementary effect for shielding from particles emitted from a radiation source.
