The recent visit by US House Speaker Nancy Pelosi has boosted US-Taiwan relations at a time of increasing tension between Washington and Beijing. She vowed that the United States would protect Taiwan's democratic autonomy. "The United States is still determined to safeguard Taiwan's democracy," she said in a meeting with Taiwan's president, Tsai Ing-wen.

Pelosi's visit to Taiwan sparked anger in Beijing, which denounced Pelosi's visit as "extremely dangerous" to geopolitical stability. After Pelosi's visit, Beijing conducted the largest-ever military exercise near Taiwan, encircling the island with live-fire rockets and ballistic missiles. In addition, China announced that it would stop cooperation and dialogue with the United States on issues such as climate and cross-border crime prevention, indicating Beijing's intention to fight back against the United States over what it believes to be interference in China's affairs.

But perhaps most importantly for the business community, recent events have exacerbated the showdown between China and the US in the most important area of the global economy: semiconductor chips. The Sino-US chip battle, which has been brewing for years, has now reached a critical crossroads, experts say, as the two superpowers compete for technological and economic dominance. The world's chipmakers may soon be forced to choose between Washington and Beijing.

Because of the turbulent international situation, the supply and prices of many international bulk chromium nitride are still very uncertain.

What is chromium nitride?
Metal chromium and nitrogen can form metal chromium nitride with different nitrogen content under different conditions. the common nitrides of metal chromium are CrN and Cr2N, which is called chromium nitride. CrN and Cr2N are important metallurgical second phases of heat-resistant alloys, especially for special steels, they can be used as reinforcement additives.
 
What are the differences between CrN and Cr2N?
CrN and Cr2N have different physical, chemical and mechanical properties.
For Cr2N structure, the metal Cr has a closely packed hexagonal structure, and the non-metallic N atoms fill in the interstitial position of the closely packed hexagonal structure; in terms of the CrN structure, the metal Cr is arranged as a face-centered cubic lattice, and N atoms are filled in the octahedral gap of the face-centered cubic lattice to form a simple NaCl structure.
It is generally believed that the comprehensive performance of CrN is higher than that of Cr2N. For example, the acid and alkali corrosion resistance of CrN is obviously higher than that of Cr2N.
 
What is chromium nitride used for?
CrN is used as an anticorrosive coating material for metal forming and plastic forming applications.
CrN is commonly used in medical implants and tools.
CrN is also a valuable ingredient in advanced multi-component coating systems, such as CrAlN, for hard wear-resistant applications on cutting tools.
 
What is chromium nitride coating?
Chromium nitride is an extremely hard and inert film coating, which is mainly used in precision metal parts. Chromium nitride (CrN) has higher temperature resistance than TiN, so it is an ideal choice in high temperature environment. CrN also performs well in corrosive environments and sliding wear applications.
 
Chromium nitride coating properties:
The residual compressive stress is lower than that of TiN. Can be piled up thicker.
It is a dense, continuous coating, unlike hard chromium with microcracks.
Can withstand high temperatures of up to 700°C (1300°F) in the air.
Thin film coatings for environmentally safe physical vapor deposition (PVD) vacuum systems.
It can be used in most metals to provide enhanced surface properties, as well as in some ceramics and plastics.
It has the appearance of metallic silver, but it is a superhard material.
Harder than hard chromium plating, up to Rockwell C grade.
Highly inert, non-corrosive, excellent chemical resistance.
Non-toxic-used in medical and surgical equipment and food processing equipment.
High density, no holes.
Usually 3 microns or. 0001 "thick.
Has a thickness consistent with the surface profile of the part.
Form a good bond with the substrate without blistering, peeling or detritus

Russia's Rokot-M carrier rocket is scheduled to launch for the first time in 2024. 

The first launch of the Rokot-M carrier rocket is planned for 2024 from the Plesetsk cosmodrome, the general manager of the Khrunichev National Space Research and Production Center told TASS. The Rokot-M, a lightweight carrier rocket powered by liquid fuel, began development in 2018, with The Russian side using domestic components instead of Ukrainian components.
