Coatings

The coatings industry involves the application of a thin layer of material to a substrate to improve its properties such as corrosion resistance, wear resistance, and thermal protection. Coatings are widely used in various industries, such as automotive, aerospace and construction. The coatings industry has specific requirements for the particle size and morphology of the powder used in coatings to ensure consistent coating quality and performance. The powder used in coatings should have a narrow size distribution and spherical particle morphology to ensure uniform and dense coatings.

Why Powders?

Metal powders are used as the primary raw material in the production of coatings. The metal powders are mixed with other materials such as solvents, binders, and additives to form a coating solution. The coating solution is applied to the substrate using various techniques such as spray coating, electrostatic coating, and dip coating. Metal powders used in coatings should have a specific particle size and morphology to ensure uniform and dense coatings. 


ATO Lab Plus ultrasonic metal powder atomizers produce high quality metal powders with excellent flowability, narrow size distribution and spherical particle morphology. These powder properties ensure uniform and dense coatings, which are essential for coating applications. The high flowability of ATO metal powders makes it easier to mix and disperse the powders in coating solutions, resulting in consistent coating quality. The narrow size distribution of ATO metal powders ensures a uniform and homogeneous coating layer, and the spherical particle morphology improves packing density and substrate adhesion.


The alloys used in coatings depend on the specific application and requirements. Some commonly used alloys in coatings are aluminum, zinc, magnesium and copper alloys. These alloys provide excellent corrosion resistance, wear resistance and thermal protection. Special alloys such as nickel-chromium alloys and titanium alloys are also used for high temperature applications.

Examples of Metal powder applications
in Coatings industry

Corrosion-resistant coatings

High-purity metal powders with exceptional corrosion resistance, like those found in aluminum and zinc alloys, are needed for these coatings. For uniform and dense coatings, the powder should have a narrow size distribution and spherical particle morphology.

Wear-resistant coatings

These coatings need materials that are hard and resistant to wear, like alloys made of nickel and tungsten carbide. For uniform and dense coatings, the powder should have a narrow size distribution and spherical particle morphology.

Thermal barrier coatings

Low thermal conductivity materials, like ceramic-metal composites, are necessary for these coatings. For uniform and dense coatings, the powder should have a narrow size distribution and spherical particle morphology.
