Color Laser Marking Of Stainless Steel
Jan 05, 2018

Laser marking has been from the beginning of the high speed development to a stable development stage, in the domestic application is more extensive, then in order to seek business development a new point of growth, the emergence of new technology of stainless color marking marking of stainless steel in the field of development, create another the era of laser marking, the metal material surface can produce a variety of colors.

The principle of color rendering of stainless steel:

There are three kinds of color: one is to generate colored oxide; two is chemically and electrochemically or under the action of laser generated colorless transparent oxide thin film on the surface of stainless steel, produce interference effect, can show color in the surface; three is a mixed state at the same time there is colored oxide and oxide film.

The relationship between color change and laser energy in laser color marking of stainless steel:

Laser heat effect on the surface of stainless steel under the action of laser.  Through the thermal effect of laser, it is concluded that the density of the laser energy is proportional to the thickness of the film. With the increase of laser energy, the surface of the stainless steel color according to the following order changes color: Orange - red - Purple - Blue - Green - Blue - Green - Green - yellow - Orange - red.

Stainless steel marking advantage:

May want to edit text pattern, very convenient and easy to operate: the absolute environmental protection, no pollution, the stainless steel products industry, the application of color laser marking can add mark image color, can enhance the large stainless steel products, the added value of products and enhance the international competitiveness of stainless steel products in china.
