Mining Industry Thermal Spray Coatings

Few tasks are tougher than digging and drilling deep into the earth. Mining usually occurs in remote locations, under strict timelines, in challenging conditions. Extracting, separating, and processing critical ores, minerals and elements can grind down even the toughest machines. Astro Alloys Inc. supplies high-quality, long-lasting thermal spray coatings that effectively and efficiently protect and preserve hard-working mining equipment from the most demanding conditions and applications.

Thermal spray coatings for mining applications enhance the material properties of parts to help resist wear and tear, prevent corrosion and rusting, and improve overall endurance and performance. Durable and reliable mining thermal spray coatings also prolong the life of mining equipment and parts, which decreases downtime for repairs and maintenance, saves you money, and increases productivity.

Thermal Spray Powders For The Mining Industry

For the mining industry, Astro Alloys manufactures high-performing, long-lasting chromium carbide, tungsten carbide, and ceramic thermal spray especially effective to combat corrosion, prevent wear and tear, and extend the service life of mining parts subjected to extreme and harsh working conditions.

Chromium Carbide Powders

Chromium carbide thermal spray powders result in a dense, well-bonded, very hard coating that is well suited for fretting and abrasive wear, and hard surfacing.  These coatings stand up to high temperatures and can offer resistance to corrosion, heat, and oxidation in temperatures up to 1500F.

Tungsten Carbide Powders

Astro Alloys offers Praxair tungsten carbide thermal spray powders, known for their hardness and wear resistance. Tungsten carbide thermal spray powder creates a dense, hard, and tough coating. Tungsten carbide powders are commonly used in applications involving sliding wear erosion, impingement, abrasion, and fretting wear.

Ceramic Spray Powders

Astro Alloys offers a broad range of advanced ceramic spray powders, manufactured by Praxair. These ceramic thermal spray coatings include low thermal conductivity thermal barrier coating (TBC) powders to high purity aluminum and yttrium coatings.
