Marcado ultraestable de alta precisión con láser de nanosegundos en acero inoxidable

En 1999, Ann Marie Carey hizo un intento preliminar de marcar con láser en color los tazones de niobio, lo que hizo factible el marcado con láser en color de artesanías de metal y joyería.

El marcado de color láser hace que el efecto de presentación del patrón sea más diversificado. El objeto marcado se despide del color monocromático, se mejora la jerarquía de colores, la imagen es realista y se mejora la calidad del producto. Es una innovación a la artesanía tradicional. Desde entonces, el ámbito de aplicación del marcado láser en color ha seguido ampliándose y también se ha convertido en un nuevo medio tecnológico para mejorar el valor añadido de los productos.

Láser ultravioleta RFH 355NM

The reason why human eyes can distinguish different colors is actually because when light shines on the surface of an object, it reflects light of different wavelengths. These different wavelengths of light are captured by the cells of the naked eye and processed by the brain to distinguish them. The feeling of different colors. Returning to stainless steel, the various colors that can be obtained after laser treatment are the same.

Laser color marking adds new colors to stainless steel

Analyzing the principle of color development of stainless steel from physical properties, the changes before and after laser processing of stainless steel are nothing more than three ways:

1. Generate colored oxides

2. Under the action of chemistry, electrochemistry or laser, a very thin colorless and transparent oxide film is formed on the surface of stainless steel. The oxide film produces interference effects and can show colors on the surface.

3. There is a mixed state of colored oxide and oxide film at the same time

Nanosecond UV laser marking

The stainless steel material for laser color marking will generate colored oxides on the surface under the action of the laser heat source, or a colorless and transparent oxide film will appear in various colors due to the light film interference effect. This is stainless steel color marking The basic principle is that under the action of laser, the surface of stainless steel has a laser thermal effect, and the laser energy is different, and the surface of stainless steel also shows different colors.
