Air Plasma Coatings
Achieve superior protection with our advanced air plasma spray thermal barrier and wear resistant coatings. Ideal for a wide range of materials and applications.
Air plasma spray is a highly efficient and versatile method used for applying coatings on various substrates. The process utilizes electrical energy to ionize a gas stream, producing a high-temperature (10,000C) ‘flame’ to heat and accelerate powder feedstock.
The flame is extremely efficient at heating high melting point, and low thermal conductivity materials, being particularly suited to spraying ceramics or oxides.
What is APS coating?
Air plasma spray is an innovative and versatile technique used for various surface treatments and hard facing applications.
This method utilizes a high-temperature plasma arc to melt and propel particles onto a substrate, creating a protective coating. One of the key materials used in air plasma spray is zirconium oxide, which is known for its exceptional thermal barrier properties. By applying zirconium oxide coatings using air plasma spray, hot parts such as blades and nozzles in gas turbines can be effectively protected from high temperatures and thermal stresses. This technology has been continuously developing to enhance the performance and durability of these critical components.
Another material commonly used in air plasma spray is chromium oxide. Chromium oxide is a high hardness ceramic material that offers excellent tribological properties, including high wear resistance. Coatings made from chromium oxide are widely used in various industries to improve the wear properties of components. The air plasma spray process allows for precise application of chromium oxide coatings, ensuring optimal performance and longevity.
In addition to zirconium oxide and chromium oxide, air plasma spray can also be used to apply materials like tungsten or chrome carbides, aluminum oxide, titanium dioxide, and magnesium zirconate. These materials offer unique properties that can address different issues such as wear, erosion, abrasion, corrosion, and high temperature environments. With air plasma spray, manufacturers have the flexibility to choose the most suitable materials for their specific needs.
Advantages of Air Plasma coating
Air Plasma Spray coatings offer numerous advantages in various industries. One of the main advantages of Air Plasma Spray coatings is their ability to provide superior protection against Thermal fatigue, wear, oxidation and corrosion.
These coatings are extremely durable and can withstand harsh environmental conditions, making them ideal for applications where components are exposed to high temperatures, chemicals, or abrasive materials.
Additionally, Air Plasma Spray coatings can be applied to complex shapes and surfaces, providing a uniform and seamless protective layer. This makes them highly versatile and suitable for a wide range of applications, including aerospace, automotive, and power generation industries. Overall, the advantages of Air Plasma Spray coatings make them a popular choice for improving the performance and longevity of critical components.
