High-Power 355 nm Ultraviolet Laser marking alumina black

With the continuous change of consumption concepts and the country's vigorous promotion of low-carbon environmental protection, the requirements for various electronic product manufacturing industries are getting higher and higher. Dear merchants, do you hope that the anti-counterfeiting ability of your products on the basis of environmental protection cannot be imitated? Do you want to increase the added value of your products? Do you want to improve your product grade and brand sense? Come to learn about alumina blackening and mark the distinctive logo to give you a different experience.

Nanosecond UV laser marking anodized aluminum

The mechanism of blackening of anodized aluminum is to further oxidize the anodic aluminum layer with a thickness of 5-20um and change the surface material in a short period of time by focusing a high-energy density laser. The principle of blackening of aluminum is based on nano The effect is that the size of the oxide particles is nanometer-sized after laser processing, so that the light absorption performance of the substance is increased, so that visible light is irradiated on the substance and absorbed, and the reflected visible light is very small, so that it is black when viewed with the naked eye. At present, the mobile phone LOOG and adaptation information on the market use laser marking technology.

The relationship between the corresponding effects and time of different pulse widths of alumina blackening is as follows:

Compared with M1+, M6+ has higher blacking efficiency; it can adapt to materials with thin oxide layer and poor oxidation; and the marking effect is consistent.
