1. A cold sprayed metal coated article comprising:
a polymeric material having at least one surface;
an electrochemical insulating layer on the at least one surface, wherein at least a portion of the electrochemical insulating layer comprises a non-conductive polymer, a cemented carbide alloy, or a combination thereof, and a metal-metal oxide composite; and
a cold sprayed aluminum or aluminum alloy coating present on the electrochemical insulating layer;
at least one additional conductive layer, the at least one additional conductive layer sandwiching at least a portion of the aluminum or aluminum alloy coating between the at least one additional conductive layer and the electrochemical insulating layer; and
the cold sprayed metal coated article having one or more of electromagnetic interference shielding, electromagnetic emission shielding, or lightning strike protection.
