Abstract
In order to improve the surface quality of copper after laser surface remelting, this article takes laser frequency, pulse width and current as the research objects, and uses scanning electron microscopy (SEM), laser confocal three-dimensional measurement instrument, and friction and wear measurement instrument to study the surface morphology, surface roughness, and wear resistance of copper under different parameters. The results indicate that the frequency, pulse width, and current of laser surface remelting can directly affect the surface quality of the sample, but the influence of frequency and pulse width is more significant. When the laser remelting frequency is 10 Hz, the pulse width is 10 ms, and current is 100 A, the sample exhibits good surface morphology, roughness, and wear resistance. The relevant research in this article can provide a good reference for laser surface treatment of copper-based materials.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
