研究目的
Investigating the effects of laser irradiation on the copper electrodeposition process and coating quality.
研究成果
The deposition rate may be increased, and the coating quality may be improved by laser irradiation with the proper single-pulsed energy. This is due to an increase in the conductivity and diffusion coefficient of the solution, arising from an increase in the solution temperature and the local stirring induced by plasma bubbles. The grain size and growth direction of the dendrite are also affected by laser irradiation.
研究不足
The study is limited to the effects of laser irradiation on copper electrodeposition and does not explore other metals or materials. The optimal single-pulsed energy for laser irradiation may vary depending on specific conditions.
1：Experimental Design and Method Selection:
A hybrid pulsed laser and electrochemical processing technique was used to deposit a copper coating on a stainless steel substrate. The laser irradiation mechanism was studied by detecting the mechanical and thermal effects.
2：Sample Selection and Data Sources:
Electrodeposition samples were irradiated by lasers with varying single-pulsed energies and compared.
3：List of Experimental Equipment and Materials:
Scanning electron microscope (SEM) for observing the grains of the coating, and a UTM4000 series electronic universal testing machine for measuring the tensile strength and ductility.
4：Experimental Procedures and Operational Workflow:
The electrodeposition samples were irradiated by lasers with varying single-pulsed energies. The grains of the coating were observed, and the tensile strength and ductility were measured.
5：Data Analysis Methods:
The results were analyzed to understand the effects of laser irradiation on the deposition rate and coating quality.
