Laser cleaning machine laser surface treatment technology is a method of improving the surface properties of workpieces by designing and laser improving the surface of the workpiece. Laser technology can quickly heat up and play a greater role in modifying the surface of materials. The laser surface modification technologies used in magnesium alloys are mainly laser melting, laser alloying and laser cladding.

Magnesium alloys have low density, high specific strength and specific stiffness, good thermal conductivity, good electromagnetic shielding properties and damping shock absorption capabilities. They are widely used in aerospace, automobile, computer, communication and other industries. However, due to the poor wear resistance and corrosion resistance of magnesium alloys, the surface treatment technology of magnesium alloys needs to be solved urgently. Laser surface treatment technology just solves this problem perfectly.

Analysis of solutions for applying laser surface treatment technology of laser cleaning machine to magnesium alloys:

1. Laser surface treatment technology of magnesium alloys: laser surface cladding

Magnesium alloy laser cladding surface treatment does not require harsh environmental conditions such as vacuum, so the size of the workpiece is less restricted. Laser cladding technology is a rapid solidification process that uses a high-energy density laser beam to quickly melt alloys with different compositions and properties with the substrate surface, forming an alloy layer with completely different compositions and properties from the substrate on the substrate surface. The generated surface alloy layer isolates the substrate from the corrosive medium, and the corrosion properties of the material are determined by the alloy layer.

2. Laser surface alloying of magnesium alloys

Laser cleaning machine laser surface alloying is to melt the film layer and part of the substrate pre-coated on the substrate surface, or inject certain powders while the surface is melted, and the film layer or surface is rapidly solidified after liquid mixing in the molten pool, thereby forming a thin layer of alloy with desired properties on the surface to improve the performance of the substrate.

3. Laser surface treatment technology of magnesium alloy: laser surface melting

Laser melting of laser cleaning machine uses high-power density laser to interact with metal in a very short time, instantly heating the local area of the metal surface to a very high temperature and melting it, and then using the cold metal matrix to absorb heat and transfer heat to make the molten metal surface quickly solidify, thereby changing the surface structure and performance of the parts. Laser melting improves the surface hardness, wear resistance, corrosion resistance, strength and high temperature performance of metal materials and parts.
