How to mark the different colors on stainless steel by fiber laser marking machine?
STYLECNC focused on laser marking machine for many years, it has rich experience of laser marking machine. Today we will explore how the fiber laser marking machine mark the different colors on stainless steel. We should know that there are 3 different ways to make the stainless steel coloration. First,Generate colored oxide.Second,By the chemical, electro chemical or under the action of laser, a thin layer of colorless transparent film are generated on the surface of stainless steel ,The oxide film thickness by precisely controlled. Because of diffraction effects, oxide films of different thicknesses can be presented in different colors.Third,In the presence of a mixed state of colored oxide and oxide film. The relationship between the color change and the laser energy in the stainless steel color laser marking: Under the laser, the stainless steel table generated the laser heat effect. By the laser heat effect, we will get the relationship between the...
