The effect of laser treatment modes on the colors of the steel 04H18H10

The purpose of the study of this article is to identify the effect of laser treatment modes on the color of the steel 04X18H10. The research methods were reduced to determining ranges for each of the parameters with an example of the desired color. The influence of laser radiation parameters: the power and frequency of laser radiation, the speed of the laser beam, the resolution of the fill of the marked object - contributes to obtaining a certain shade of the color palette according to the RAL standard. The result of the study was the data obtained, according to which it is safe to say that the speed of movement of the laser beam has a direct effect on the resulting semitone color. At high values of this parameter, the colors become closer to dark halftones, whereas a decrease in speed leads to the opposite effect, it is possible that at low speeds of the laser beam, a slower heating of the object occurs, which leads to light halftones, and with a gradual increase in speed and, accordingly, a possible increase in surface heating temperature, colors begin to form a dark tone. The results obtained by changing the fill resolution parameter make it clear that an increase in this indicator directly affects the saturation of the resulting color with its increase, whereas a decrease in the number of fill lines causes a drop in the color saturation of the marked object. Conclusion . In this paper, the influence of the factors responsible for obtaining various shades of colors during laser marking of metal is considered, a basic palette of colors is obtained for its subsequent expansion and use for artistic purposes.
