Ceramic chromium oxide spray alloy powder is a high-performance coating material mainly used in thermal spraying technology. It has high hardness, wear resistance, high-temperature oxidation resistance, and other characteristics.
The main component of ceramic chromium oxide spray alloy powder is Cr2O3, that is, chromium trioxide. This powder is suitable for two different spraying methods: supersonic spraying and plasma spraying. When using this powder, it is necessary to strictly follow the corresponding spraying process requirements, and the particle size of the powder can be adjusted as needed. The characteristics of this powder include high hardness, wear resistance and high-temperature oxidation resistance. It can maintain its performance at temperatures up to about 900°C, so it is very suitable for occasions requiring high-temperature wear resistance and high-hardness coatings. Ceramic chromium oxide spray alloy powder is widely used in various industrial fields due to its excellent physical and chemical properties, especially under harsh working conditions such as high temperature, high pressure, high speed, and high automation, to provide long-term and stable operation protection for mechanical equipment. The use of these powders not only improves the service life of the equipment but also reduces maintenance costs. It is one of the indispensable materials in modern industry.
