Military Thermal Spray Coatings

Our national security depends on military vehicles, vessels, armaments, and other defense equipment operating reliably and flawlessly when called into duty. Astro Alloys Inc. proudly manufactures high-quality, long-lasting thermal spray coatings that effectively and efficiently protect and preserve vital military and defense equipment from the punishing conditions of persistent training and potential combat - heavily wooded terrain, deserts, salt air, and seawater.

Thermal spray coatings for military vehicles, vessels, and equipment improve the material properties of parts to help resist wear and tear, prevent corrosion and rusting, and improve overall endurance and performance. Durable and reliable military thermal spray coatings also prolong the life of critical defense components, which decreases downtime for repairs and maintenance, enhances reliability, and increases productivity.

Coatings For The Defense Industry

For high-value defense and military equipment, nickel alloy, ceramic, alumina-titania ceramic, and tungsten carbide thermal spray powders are especially effective to combat corrosion, prevent wear and tear and extend the service life of parts.

Nickel-based Powders

Pure nickel spray powders are available in high, medium, and low hardness. When combined with other elements, nickel thermal spray powders form an extremely hard, resistant layer that protects carbon steels and stainless steel components from the most severe environments of erosion, corrosion, and high temperature. Aircraft and land-based turbines use a wide variety of nickel alloys to enhance the strength and corrosion resistance of critical rotating and stationary components.

Ceramic Powders

Astro Alloys offers a wide variety of ceramic powder coatings, ranging from low-thermal conductivity thermal barrier coating (TBC) powders to high-purity aluminum and yttrium coatings.

Alumina Titania Ceramic Powders

Alumina Titania thermal spray powders feature dense, hard coatings engineered to resist wear due to abrasion, fretting, cavitation, corrosion, particle erosion, and more. By combining aluminum and titanium oxides, a smooth, wear-resistant coating is formed. Alumina-titania powders are ideal for heater plates, thread guides, and tension washers. 

Tungsten Carbide Powders

Tungsten carbide powders are commonly used in applications involving sliding wear erosion, impingement, abrasion, and fretting wear while providing low-temperature wear properties. Applying a tungsten carbide thermal spray powder creates a dense, hard, and tough coating.
