<p>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.
