Color Laser Marking|Laser Marking on Stainless Steel

Want to do high-precision laser marking on stainless steel? This section explains how to set the key process parameters of laser power, frequency, and speed. It also compares anodic oxidation coloring with thermal effect coloring, and shows how different parameter settings produce different results.It is suitable for people in metal processing, electronic components, and medical instruments to get practical technical guidance.

The key to the process is precise control of the laser parameters, and the effect depends on three key factors: material composition, the configuration of the processing parameters, and environmental control.For common 304 stainless steel, it is recommended to use fiber lasers with a power of 20-50W. By adjusting the pulse frequency to 10-100kHz, and the scanning speed to 300-1500mm / s, a nanometer-level oxidized layer can be formed on the surface, which can produce a variety of colors, including yellow, gold, and blue.

In practice, one must be aware of the differences in the reactions of different materials. Stainless steel with a high chromium content is easily colored red, while low-carbon steel tends toward bronze.By adjusting the focal length (recommended range: ± 0.5 mm), the laser energy density can be changed, and by using a combination of argon and nitrogen as the auxiliary gas, color saturation can be increased.When the power is 30 W, the speed is 800 mm / s, and the Q frequency is 25 kHz, the results are stable blue-purple marks with color difference values Δ E <1.5.

We recommend that customers regularly calibrate their galvo mirrors and that they keep the environment at 25 ± 3 degrees centigrade and 40-60 % relative humidity to ensure color consistency.For complicated patterns that require multiple colors, a layering technique can be used, with a 5-10 minute cooling period between each layer.Finally, a polishing process of 2,000 grit is used to make the colors brighter and more lasting.
