On November 24th, 2010, the Ningbo International Auto Parts & Accessories (Import) Import & Export Fair kicked off at the International Automobile City, with more than 500 domestic auto parts manufacturers and more than 300 purchasers from 28 countries and regions. And more than 200 foreign trade companies and foreign procurement office representatives attended the meeting. China Railway Auto Service Co., Ltd., a subsidiary of the China Railway Group, even throws a 200 million yuan purchase order at the scene.
As the annual event of the auto parts industry in the Yangtze River Delta, the Ningbo International Auto Parts & Accessories (Import) Import & Export Fair has been successfully held for three sessions, directly or indirectly resulting in a transaction volume of more than one billion US dollars. With the help of the International Auto Parts Import and Export Fair On a platform, Ningbo has gradually become the east gate of domestic auto parts companies and the status of the global auto parts procurement center has gradually emerged.
China Iron & Steel Auto Parts Co., Ltd. has purchased a large purchase order of RMB 200 million to entrust Ningbo Automobile City with concrete implementation, and will purchase auto parts, tires, and automobile accessories, etc., for the use of subordinate automobile repair networks. Next year, the procurement of China Railway Auto Parts will expand to 500 million yuan. In addition to China Railway Auto Parts, Shanghai Dongfang Auto Parts City and Geely Group also announced the procurement of commodities catalog on the day before. The total purchase amount exceeded RMB 500 million.
As an important R&D and production base for the domestic auto parts industry, in recent years, the Ningbo auto parts industry has developed rapidly, with an average annual growth rate exceeding 20%. Ningbo now has more than 3,000 auto parts manufacturing companies, accounting for 40% of Zhejiang Province, of which 624 above-scale enterprises.
Oxide powder for thermal spray refers to a type of powder material that is used in thermal spray processes. Thermal spray is a coating technique where a material in powder form is heated and propelled onto a substrate, forming a coating.
Oxide powders are commonly used in thermal spray applications due to their high melting points, excellent wear resistance, and thermal insulation properties. They can be used to create protective coatings on various surfaces, such as metals, ceramics, and plastics.
Some common types of oxide powders used in thermal spray include:
1. Aluminum oxide (Al2O3): This oxide powder is widely used for its high hardness, wear resistance, and thermal insulation properties. It is commonly used for coating applications in industries such as aerospace, automotive, and electronics.
2. Zirconium oxide (ZrO2): Zirconium oxide powder is known for its high melting point and excellent thermal barrier properties. It is often used in thermal spray coatings for gas turbine engine components, where thermal insulation is critical.
3. Chromium oxide (Cr2O3): Chromium oxide powder is used for its high hardness, corrosion resistance, and wear resistance. It is commonly used in applications where high temperature and abrasive wear resistance are required.
4. Titanium oxide (TiO2): Titanium oxide powder is known for its high refractive index and excellent UV resistance. It is often used in thermal spray coatings for optical and decorative applications.
These oxide powders can be applied using various thermal spray techniques, such as flame spraying, plasma spraying, or high-velocity oxy-fuel (HVOF) spraying. The choice of oxide powder and thermal spray technique depends on the specific application requirements and desired coating properties.
