The anodic dissolution of copper in chloride electrolytes with different pH has been investigated by using polarization measurements and digital holography. In acidic and neutral NaCl solutions, the oxidation processes of copper are almost the same: copper firstly dissolves as cuprous ions, which then produces the CuCl salt layer. The dissolution rate in the acidic solution is a little higher than that in the neutral. However, the mechanism is quite different in the alkaline NaCl solution: copper turns passive easily due to the formation of a relatively stable Cu 2 O film which results in pitting, and the dissolution rate of copper decreases before pit initiation.

Laser melting technology is a new surface fabrication technique, and using laser beams to improve the mechanical properties of iron-based amorphous prepared by laser melting has become a hot topic in current materials research. Firstly, nickel-plated carbon nanotubes were used to improve the toughness of iron-based amorphous coatings, and nickel-plated carbon nanotubes were used to prepare iron-based amorphous composite fusion cladding layers. Then, the iron-based amorphous has good strength, strong wear resistance and corrosion resistance and is a good surface modification material. Finally, considering that the preparation of iron-based amorphous coating by laser melting technology can meet the preparation requirements of fast cooling of iron-based amorphous, the organization and mechanical properties of the iron-based amorphous coating are studied and analyzed by using laser melting technology. The results show that the toughness of the amorphous-1.00 wt% nickel-plated carbon nanotube composite clad layer is 7.67 MPa-m which is 33.4% higher than the amorphous clad layer. The composite clad layer with the addition of carbon nanotubes showed a significant increase in toughness without a significant decrease in hardness, and the prepared nickel-plated carbon nanotube/amorphous composite clad layer had better overall mechanical properties. This study improves the mechanical properties of iron-based amorphous coatings, which is important to improve the problems of decreasing service life and stability of equipment and components caused by corrosion and wear.
