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.
Guangdong spotted tires found 30% failed
The Guangdong Provincial Administration for Industry and Commerce recently sampled 78 tires in the circulation of tires and monitored the quality of tires. It was found that the intensity of performance and unqualified marks accounted for more than 30% of the total number of samples tested. To this end, the Guangdong Administration for Industry and Commerce issued guidelines for the purchase and use of tires for automobiles and motorcycles.
According to the consumer guidelines issued by the Guangdong Administration for Industry and Commerce, the quality of automobile tires, retreaded tires and motorcycle tires is directly related to the personal safety of the citizens. To avoid safety incidents, consumers should pay attention to the following issues when purchasing and using tires:
1. The unqualified samples with the same name and tire of the same model shall not be sold without quality rectification. Consumers should not purchase the relevant tire products.
2. According to the vehicle hub specifications, select the tires of the corresponding specifications.
3. Choose a tire that has a complete package. The purpose is to trace the company after a quality problem. The complete package includes the production company, address, and telephone.
4. Choose the tire with a complete logo. Tire marks generally contain information such as specifications, hierarchy, speed grades, standard rims, maximum loads and corresponding air pressure, no inner signs, directions for use, retreaded tire signs, number of retreads, and "CCC" mark. At the same time, you should carefully check the appearance of the tire surface defects. Special attention should be paid to the consistent inside and outside packaging.
5. Use the tire correctly. The tire should be inflated according to the air pressure on the tire mark, and the tire should be periodically pressurized. When the tire wears to the mark of wear, new tires should be replaced in time to avoid safety accidents.
