Effect of Laser Single Pulse Energy on Micro-structural, Mechanical and Corrosion Properties of Amorphous Ni-Fe-P Alloy Prepared by Laser-Assisted Electrodeposition

Investigation of the Enhancement Mechanism of Electrochemically Deposited Ni–Co–W Coatings via Laser Irradiation: Effect of W Contents on Corrosion Resistance

“…Laser irradiation caused an increase in the solution temperature and cathodic overpotential. Subsequently, cathodic metal ion reduction and crystallization rates accelerated …”

“…Second, the vacuoles generated by the laser in the solution cause vacuolar pulsation and collapse jet impacts, which remove impurities from the coating in time while improving the coating flatness. Again, laser irradiation increased the temperature of the electrolyte microregion, accelerating mass transfer and suppressing concentration polarization . The temperature rise also leads to faster formation of new nuclei, refinement of grains, and reduction of round cell-like protrusions.…”

“…The introduction of laser irradiation, which is a multienergy field composite deposition technology that uses a high-energy laser beam coupled with multiple physical fields (electric, stress, temperature fields, etc.) to form a composite effect (thermoelectric, force–electric, and photoelectric effects) for processing, in the ECD Ni–Co–W increased the deposition rate, deposition quality, and overall properties at room temperature . Von Gutfeld et al was the first to introduce laser irradiation in ECD systems and found that laser irradiation caused an abrupt increase in the microzone current density.…”

“…Von Gutfeld et al was the first to introduce laser irradiation in ECD systems and found that laser irradiation caused an abrupt increase in the microzone current density. In previous studies, ,− laser irradiation was discovered to enhance the electrode potential, expedite deposition and reduction, and cause grain refinement. Laser electrochemical deposition (LECD) is an effective composite processing method that improves surface quality and overall performance.…”

“…to form a composite effect (thermoelectric, force−electric, and photoelectric effects) for processing, 13 in the ECD Ni−Co−W increased the deposition rate, deposition quality, and overall properties at room temperature. 14 Von Gutfeld et al 15 was the first to introduce laser irradiation in ECD systems and found that laser irradiation caused an abrupt increase in the microzone current density. In previous studies, 14,16−18 laser irradiation was discovered to enhance the electrode potential, expedite deposition and reduction, and cause grain refinement.…”
