Diamond film application field and prospects

Due to its relatively low cost and the ability to grow a continuous polycrystalline film on a substrate, it has a very important and broad application prospect as shown below. Table 1 Important Application Fields of CVD Diamond Films Table 2 D.Dsand Market Statistics and Forecasts World CVD Diamond Market (Unit: Million US Dollars) Note: Statistics from International Resouceinc Research Report According to a company estimate, 1986 The annual value of infrared materials is between 7,000 and 75 million US dollars, and in 1991 it was 1.1 to 120 million US dollars. In 1992, diamond infrared materials accounted for 10% of the total infrared materials. Finally, we will see almost all far infrared observation windows and missile hoods. Diamond film coating technology will be used. Diamond film coated tools will not only compete with PCD tools in the future, but will also affect the uncoated carbide and ceramic tool market. Diamond film tools, thermal and optical applications account for more than 80% of the total market, but the application of diamond films in military optics cannot be ignored. Experts predict that by 2020, the market for diamond film direct products will exceed 10 billion US dollars, equivalent to several times the HT-HP synthetic diamond market. Although the key technologies for some processing and preparation of diamond films have not been solved, resulting in the actual market scale being lower than the predicted results, it is clear that the resolution of certain problems will make the diamond film market double or even order of magnitude. increase.
