Patent ID: 8402915

Claim:
A composite coating apparatus, comprising: a first device configured for forming nanoscale particles on an electrically conductive workpiece, comprising: a Q-switch laser source configured for providing impulse laser light beams; a first liquid-ejecting member comprising a first chamber for accommodating electrolyte liquid, a first light incident through hole, and a first electrically conductive bottom wall comprising a first liquid ejecting through hole, the first liquid ejecting through hole aligned with the first light incident through hole, the first liquid-ejecting member configured for ejecting the electrolyte liquid from the first chamber through the first liquid ejecting through hole; and a first hollow light guide conduit comprising a first end coupled with the first light incident through hole and a second end spaced from the first liquid ejecting through hole, configured for guiding the impulse laser light beams to the first liquid ejecting through hole; and a second device configured for forming a metallic film on the nanoscale particles, wherein the second device includes: a continuous laser source for providing continuous laser light beams; a second liquid-ejecting member comprising a second light incident through hole, a second chamber for accommodating electrolyte liquid, and a second electrically conductive bottom wall comprising a second liquid ejecting through hole, the second liquid ejecting through hole aligned with the second light incident through hole, the second liquid-ejecting member configured for ejecting the electrolyte liquid from the second chamber through the second liquid ejecting through hole; and a second hollow light guide conduit comprising a first end coupled with the second light incident through hole and a second end spaced from the second liquid ejecting through hole, configured for guiding the continuous laser light beams to the second liquid ejecting through hole.
