Ceramic Blackening Process Exploration | UV Laser Application on Ceramic Materials

In modern industry, ceramic materials are widely used in various fields due to their excellent physical and chemical properties. From precision electronic components to harsh industrial equipment, ceramics, with its irreplaceable advantages, has become one of the most important materials to promote technological progress. However, how to make lasting and clear markings on these materials has always been a challenge in industrial processing. With the development of laser technology, laser ceramic blackening technology came into being, providing an efficient and environmentally friendly solution to this problem.

Comparison of traditional processing methods and laser processing methods

Traditional ceramic blackening technology mainly relies on mechanical engraving or chemical etching and other methods. These methods not only have low precision, low efficiency, easy to damage the material and other issues, but also more supplies, environmental pollution, does not meet the modern concept of green manufacturing.

Laser processing technology, especially solid-state ultraviolet laser technology, non-contact, no consumables, clear marking, high temperature resistance, not easy to fade, processing flexibility and other advantages, to become the ideal choice for ceramic blackening process. The high energy density and short pulse width of solid-state UV lasers enable precise control of the process, realizing fine blackening of ceramic surfaces while maintaining the original physical properties of the material.

GZTECH 15W UV laser marking effect

In ceramic blackening technology, 15W UV laser is a commonly used light source. Its high energy density laser beam can act on the ceramic surface quickly and precisely to form a clear, long-lasting black mark. By adjusting the parameters of the laser, blackening of ceramics of different materials can be realized. At the same time, 15W UV laser also has easy operation, good stability and other characteristics, for ceramic blackening technology provides a strong guarantee. However, in the use of 15W UV laser ceramic blackening, also need to pay attention to the control of the single pulse energy. Single pulse energy is too low may lead to blackening effect is not ideal, while single pulse energy is too high may damage the ceramic surface. Therefore, the actual application needs to be adjusted and optimized according to the specific circumstances.

Comparison of marking with different power UV lasers

White ceramics are mainly alumina, zirconia, etc. Due to their different reference content, the laser marking effect will be different. Taking alumina ceramics as an example, the processing speed comparison of different power lasers under the same effect is as follows:

                                       Comparison of processing speed of different power lasers under the same effect

Under the same efficiency, the effect of different power lasers on ceramic blackening is different. The actual test marking results are as follows:

                                           Different effects of 15W, 10W and 5W marking under the same efficiency

From the above, it can be seen that the power of the laser has an important influence on the processing efficiency and effect. With the increase of laser power, the processing speed under the same effect shows a clear trend of improvement. 5W laser due to low power, its marking blackness is relatively limited, but in some specific scenes can still meet the demand; 10W and 15W UV lasers have higher power and faster processing speed, in order to ensure that the processing speed, at the same time, can achieve a higher quality of marking effect, and become the mainstream choice in ceramic blackening process. The mainstream choice in the process. In the actual application, according to the specific needs of the selection of the appropriate laser model and parameters.
