Abstract
Coatings comprising iron alloys that include iron and at least another metal (e.g., cobalt and/or nickel) for wireless recharging devices are generally described. The coatings may be directly applied to a substrate, such as a print circuit board.
Claims18
An article, comprising:
- a coil;
- and
- a metallic coating comprising an iron alloy deposited on the coil,
- wherein a crystal structure of the iron alloy comprises hexagonal close packed unit cells,
- wherein at least a portion of a surface of the coil is free of the metallic coating.
2 more elements
A circuit board, comprising:
- a plurality of traces on the circuit board, and
- a metallic coating comprising an iron alloy deposited on a first trace of the plurality of traces;
- wherein a crystal structure of the iron alloy comprises hexagonal close packed unit cells,
- wherein a portion of the first trace is free of the metallic coating.
1 more element
A method of fabricating a coil on a circuit board, the method comprising:
- forming a first trace on the circuit board;
- and
- coating the first trace with a metallic coating comprising an iron alloy,
- wherein a crystal structure of the iron alloy comprises hexagonal close packed unit cells,
- wherein at least a portion of the first trace is free of the metallic coating.
2 more elements
The method of 13, wherein at least one surface of the first trace is free of the metallic coating.
