Research Status of Surface Modification of Metal Biomaterials by Low Temperature Plasma:

With the development of basic industries and high-tech products, the demand for high quality and efficient surface modification and coating technology has been extended in depth. Under the mutual promotion of this field and related disciplines, breakthroughs have been made in surface modification of metal biomaterials and coating process simulation and performance prediction. As an important part of the development of new metal biomaterials, surface modification and coating technology have penetrated into the traditional industry and high-tech industry sectors, and in turn promoted the further development of surface functional coating technology according to the application requirements. It has become an important research direction of low-temperature plasma surface modification technology to design the material surface, cut the surface performance parameters to meet the specific requirements, and further realize the prediction of the structure and properties of the surface coating. Various plasma vapor deposition is the world famous research institutes and universities to carry out a challenging research topic, overseas has the plasma chemical vapor deposition (PCVD), and other surface modification method was carried out by computer simulation, in view of the PCVD process was simulated, the macroscopic and microscopic multi-level model, the plasma technology and coating of various properties and simulate and predict the adhesion strength of the matrix; Computer simulation of the performance stress of the permeable layer on the metal surface can better control and optimize the process.

Low Temperature Plasma

In the future according to the development of the plasma surface modification technology at home and abroad, combined with the demand and status quo of biomedical engineering, in a batch of advanced applied during the development of metal material surface function cladding, key technologies, including new type of low temperature plasma vapor deposition technology and equipment, surface coating technology and the quality of the research and development of the numerical simulation and optimization control and so on.

To sum up, low-temperature plasma technology is doing a lot of research on surface modification and surface film synthesis of metal biomaterials due to its unique advantages, but most of these studies are still in the development stage or test stage. With the further study of plasma theory and the solution of technological problems, the surface modification technology of low-temperature plasma will certainly improve the biological properties of metal materials, reduce toxic and side effects, and play a positive role in medical application.
