Hypersonic weapons have become the focus of the “arms race” and thermal barrier coating technology has become the key
[Securities Times] it is reported that US Air Force Secretary Kendall recently told the media that the United States and China are engaged in an “arms race” to develop the deadliest hypersonic weapons, which China has been very actively promoting. In recent years, the three armed forces of the United States have competed to develop and install hypersonic weapons in parallel, The first batch of missiles of the U.S. Army’s long-range hypersonic weapon (lrhw) program is expected to be delivered next year, and the U.S. Air Force’s “air launched rapid response weapon” (arrw) is scheduled for mass production next year. The silent supersonic aircraft x-59 developed by NASA in cooperation with Loma will also make its first flight next year. Russian President Vladimir Putin said in a live television broadcast last month that Russia will obtain a new hypersonic weapon with a flight speed of more than Mach 9 in the near future.
Comments: hypersonic technology is a key technology that can change the global military power balance. China, the United States, Russia and other countries are stepping up research and development. As supersonic weapons fly at high Mach number for a long time, air friction will form ultra-high temperature on the surface, resulting in “thermal barrier”, which will affect the stability of aircraft, The preparation of a very thin layer of thermal barrier coatings (TBCs) on the surface of superalloys has become one of the keys to supersonic weapon technology and has great development potential. Huaqin technology, the first unit of military “stealth materials” of science and Technology Innovation Board held last month, also takes thermal barrier materials as one of the core technologies, and related products are under pre research and trial production.
Guangdong Kingstrong Technology Co.Ltd(300629) (300629): the thermal barrier coating products applied by kangtaiwei, a subsidiary of the company, on model x aircraft have been finalized for mass production and generated revenue.
Guangdong Orient Zirconic Ind Sci And Tech Co.Ltd(002167) (002167): the company’s stabilized zirconia has been successfully applied to thermal barrier coatings for Aeroengines.
