Color marking effect of stainless steel
In traditional laser marking, stainlesssteel is usually marked with infrared rays. This is because the laser produces an oxidation reaction on the surface of the stainless steel, forming an oxide layer, which makes the mark appear bright silver or dark gray.
However, with the advancement oftechnology, color marking can now also be achieved on stainless steel to increase the personalization and decorative effect of the product. This kind ofcolor marking is usually achieved through special chemical additives and laserparameters.
A common method is to use chemicaladditives to form a color-reactive layer on the surface of stainless steel, and then use laser to peel off the color-reactive layer to form colored marks. This
method can achieve different colors, such as black, blue, red, etc., with good appearance and scratch resistance.
Another method uses the interaction betweenlasers and chemical additives to create colored patterns directly on the surface of stainless steel. This method can achieve more colors and designs,
but requires precise control of laser parameters and chemical additive ratios.
All in all, the color marking effect ofstainless steel can be achieved through special chemical additives and laser parameters. This kind of color marking can increase the personalization and decorative effect of the product, bringing more choices and creativity to stainless steel products.
