  • Publication number: 20250125327
    Abstract: A method including melting a metallic material, converting the metallic material into an aerosolized metal spray, reducing a temperature of the aerosolized metal spray from a first temperature to a second temperature by generating a temperature gradient for transmission of the aerosolized metal spray, and transmitting the aerosolized metal spray through or using the temperature gradient. In the method a substrate is coated with the aerosolized metal spray prior to solidification of the aerosolized metal spray to form a solidified metal-to-substrate bond, which is a mechanical and an electrical bond.
