Recently, the Korea Electric Research Institute (KERI), an electric power professional research organization affiliated with the National Institute of Science and Technology of the Ministry of Science, Technology, and Information Technology of Korea, said that the research team of the Electrical Medical Device Research Center has developed a surface treatment of titanium using femtosecond lasers. Technology.
Femto second laser refers to a laser system technology. The resulting pulse has a very short time, which is equivalent to only one gigasecond, which is also a research pride of Keri Results. The pulse repetition rate and average output rate are high, and long-term operation can ensure a stable output rate, which is expected to be used in the industrial field of ultra-fine processing.
One of the key factors for the commercialization of femtosecond lasers is the processing speed. In order to use femtosecond lasers for fine processing, the existing technology mainly processes materials at a slow speed, but this method requires a lot of time and is used in industrial applications. There are still considerable difficulties.
The technology developed by KERI not only maintains the precision of femtosecond lasers, but also ensures fast processing speed. It is the best surface treatment system. The research team uses a lens with a wide field of view and a mirror surface that rotates at high speed. In combination, the femtosecond laser can also perform stable surface treatment over a wide area.
When KERI applies a femtosecond laser to the surface treatment of titanium, it can not only improve the inherent properties of titanium, but also produce functional surfaces. Generally speaking, titanium material is light in weight, high in strength, non-toxic, and can be applied to the human body. Its application in the medical field has become more common. Using femtosecond laser can prepare nano-sized tissue structure on the surface of titanium, so that its surface has hydrophilic or hydrophobic properties, making it a better therapeutic material.
It is worth mentioning that this technology developed by KERI is expected to have considerable effects in the field of dental implants or in vivo medical devices. Hydrophilic titanium after femtosecond laser treatment can be prepared into dental implants with high affinity to the human body and stable fusion with human bones, thereby greatly shortening the treatment cycle of patients; in contrast, titanium after hydrophobic treatment The material can be prepared as a medical device for transplantation in vivo, which can help reduce the foreign body reaction (resistance of the body and the body).
Chief researcher Zheng Baoshu, who participated in the research and development, said that in order to achieve the world's leading level of femtosecond laser technology, KERI is conducting research in different basic subject applications. The use of this technology for titanium surface treatment has great potential in the field of medical devices. So much attention. Through joint research in the fields of laser, materials, optics, and processing, the advantages of femtosecond lasers are maximized, and the best surface treatment system is constructed.
At present, the technology has been transferred to a material company, and it is ready for commercialization. In order to achieve true rooting of the technology, the KERI research team will continue to provide technical advice and necessary support.
