The Application of Surface Treatment Technology

There are a variety of methods for surface nanocrystallization of materials. There are a large number of surface nanocrystallization technologies. It is a surface layer which can realize the nano-characteristics by means of laser surface treatment technology and nanometer technology. It can be collectively referred to as green laser pointer surface nanocrystallization technology; More generally referred to as laser nano-surface engineering technology, is directly or mainly the use of laser this specific technical means to directly change or add material to change the surface of the solid material is treated, the composition or structure, so that the formation of nano-crystal Grain or a certain nanoparticle composition of the surface layer. Or the use of laser etching, laser embossing, laser hair, laser micro-nano modeling and other means to achieve nano-structure on the surface of the material.

The welding equipment does not need to be in contact with the bonded plastic parts. Stress and thermal stress; minimizes heat damage and thermal deformation, can be different composition or different colors of the resin bonded together; can be welded to the size of small or complex structure of the complex parts, for some complex parts can even «penetrate welding» ; No vibration technology can produce air tight or vacuum seal structure; can be a variety of different plastic welding, and other welding methods have a greater limit; equipment, high degree of automation, can be easily used for complex plastic parts processing. Specializes in welding products with complex shapes (even three dimensions); can weld areas where other methods are not easy to reach. Because of the advantages of laser pen welding, it is particularly attractive to those who seek a cleaner way to weld complex parts of the processors, such as circuit boards containing plastic products, medical equipment.

The application of surface treatment technology has a long history, but the surface engineering technology from concept to development into a complete discipline system time, and now only a few decades, laser technology and nano-technology and surface engineering technology combined with laser surface nano-technology or Also known as laser nano-surface engineering technology. Although the use of a variety of laser surface treatment technology, such as blue laser pointer irradiation, laser remelting, laser cladding and laser shock, has a lot of research data and achieved fruitful results, but specifically targeted for the use of these technologies, The research on surface nanocrystallization is still relatively small and not systematic, and the development of nano-patterning of laser surface is still in the early stage, so there is still a lot of research work in this field.

After the successful development of the high-power laser in the 1970s, the laser surface treatment technology has been put into practical application, and then the laser quenching (laser phase transformation hardening surface modification technology), laser remelting, laser surface alloying, Laser cladding, laser surface amorphization and laser impact strengthening and other methods. These red laser pointer surface treatment technology through the surface of the material to form a certain thickness of the treatment layer to improve the mechanical properties of the material surface, metallurgical properties, physical properties, thereby improving the parts, the workpiece wear, corrosion resistance, fatigue and other properties. Laser due to high power density, good direction, easy energy transfer, can be transmitted in a variety of transparent media and other characteristics. At the same time, the development of laser pulse nanometer pattern is more feasible.

At present, laser welding machine commonly used plastic welding technology mainly vibration friction welding, hot plate plastic welding and ultrasonic welding, mainly used to connect sensitive plastic products (including circuit boards), with complex geometric shapes of plastic parts and a strict clean Requirements of plastic products (medical equipment) and so on. Application of high power laser welding welding plastic parts, the advantages are: welded seam size precision, airtight and watertight; welding firm, you can get high-precision welding parts. The welding equipment does not need to be in contact with the bonded plastic parts, compared with other welding methods, greatly reduce the vibration of the products.
