Coatings For The Food & Beverage Industry

For the food and beverage industry, chromium oxides and carbide thermal spray coatings are especially effective to combat corrosion, prevent wear and tear and extend the service life of parts. These coatings are generally meant for equipment and materials that come in contact with food.

Chromium Oxide Spray Powders

Chrome oxide powders are used in wear-resistant applications due to their resistance to abrasion, corrosion, oxidation, fretting, and erosion.  They also employ high resistance to acidic and caustic solutions. Typical applications for chromium oxide spray powders include shafts, pump parts, seals, and capstans.

Chromium Carbide Powders

Chromium carbide powders provide a dense, well-bonded, resilient coating well suited to handle fretting and abrasive wear. These coatings withstand high temperatures – up to 1500 degrees – and resist corrosion and oxidation.

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.
