The influence of parameter setting of laser surface treatment technology in instrument manufacturing on the treatment effect

As an important processing method in modern industrial production, laser surface treatment technology has the advantages of high precision, fast efficiency, and good surface treatment effects, and is widely used in the fields of surface modification, surface strengthening, and surface repair of metals, non-metals, and composite materials. The setting of laser surface treatment process parameters has a direct impact on the treatment effect, and this paper will discuss it in detail.

1. Overview of laser surface treatment technology

Laser surface treatment technology is a technology that utilizes the interaction between laser beams and the surface of materials to change the microstructure of the material surface, thereby achieving the purposes of surface strengthening, surface modification, and surface repair. The main technologies of laser surface treatment include laser cladding, laser surface quenching, laser surface strengthening, and laser surface modification.

2. Parameters of laser surface treatment technology

The parameters of laser surface treatment technology mainly include laser power, laser scanning speed, laser scanning spacing, scanning trajectory, cooling method, and so on.

Laser power: The laser power directly affects the size of the laser beam's energy, thereby affecting the effect of laser surface processing. Too high a power will lead to overheating of the material surface, causing oxidation, melting, deformation, and other phenomena; too low a power is difficult to achieve the ideal processing effect.

Laser scanning speed: The laser scanning speed affects the time of the laser beam on the surface of the material, thereby affecting the effect of laser surface processing. Too fast a scanning speed will lead to uneven surface treatment of the material, while too slow a scanning speed may cause the material surface to overheat, thereby producing adverse effects.

Laser scanning spacing: The laser scanning spacing directly affects the coverage area of the laser beam on the surface of the material, thereby affecting the effect of laser surface processing. Too small a scanning spacing will lead to uneven surface treatment of the material, while too large a scanning spacing may result in poor surface treatment effect of the material.

Scanning path: The scanning path directly affects the way the laser beam covers the surface of the material, thereby affecting the effect of laser surface processing. Different scanning paths can produce different processing effects, such as linear scanning, circular scanning, and sawtooth scanning, etc.

Cooling method: The cooling method directly affects the cooling effect of the laser beam on the surface of the material, thereby affecting the effect of laser surface processing. Cooling methods include natural cooling and forced cooling, etc.

Three, the impact of laser surface processing parameters on processing effect

Laser power: The setting of laser power directly affects the size of the laser beam's energy, thereby affecting the effect of laser surface processing. Too high a laser power will lead to overheating of the material surface, causing oxidation, melting, deformation, and other phenomena; too low a laser power is difficult to achieve the ideal processing effect.

Laser scanning speed: The setting of laser scanning speed directly affects the time of the laser beam on the surface of the material, thereby affecting the effect of laser surface processing. Too fast a laser scanning speed will lead to uneven surface treatment of the material, while too slow a laser scanning speed may cause the material surface to overheat, thereby producing adverse effects.

Laser scanning spacing: The setting of laser scanning spacing directly affects the coverage area of the laser beam on the surface of the material, thereby affecting the effect of laser surface processing. Too small a laser scanning spacing will lead to uneven surface treatment of the material, while too large a laser scanning spacing may result in poor surface treatment effect of the material.

Scanning path: The setting of the scanning path directly affects the way the laser beam covers the surface of the material, thereby affecting the effect of laser surface processing. Different scanning paths can produce different processing effects, such as linear scanning, circular scanning, and sawtooth scanning, etc.

Cooling method: The setting of cooling method directly affects the cooling effect of the laser beam on the surface of the material, thereby affecting the effect of laser surface processing. Cooling methods include natural cooling and forced cooling, etc.

In summary, the setting of laser surface processing parameters has a direct impact on the processing effect. Therefore, in actual operation, it is necessary to reasonably set parameters such as laser power, laser scanning speed, laser scanning spacing, scanning path, and cooling method according to factors such as material properties and processing requirements, in order to achieve the ideal processing effect.
