Chromium Oxide Thermal Spray Powders
Saint-Gobain Coating Solutions supplies a wide range of chromium oxide-based powders with formulations tailored to meet specific process demands for optimal resistance to corrosion & wear due to abrasion, friction, fretting & erosion.
#306 & 307 Metal-Free Chromium Oxide-Titania Thermal Spray Powder
Saint-Gobain’s sintered 300 series features two blocky shaped powders. The titania present in these formulations yields superior deposit efficiency & finishing characteristics compared to pure chromium oxide. Virtually free of chromium metal, these powders produce an extremely corrosion resistant coating ideal for pumps, shafts, seals, pistons and rolls.
Coarser particle sizes allow for thicker coatings, while medium or fine cuts are used when a thinner coating is required.
#340 & 341 Chromium Oxide with Silica & Titania Thermal Spray Powder
Saint-Gobain’s #340 & 341 are sintered & crushed blocky shaped powders that produce excellent wear & corrosion resistant coatings. The presence of silica & titania increases deposit efficiency & improves finish quality when compared to pure chromium oxide powders.
These powders are used to provide coatings on pumps, shafts, seals & rolls. Powders with larger particle size are ideal for repair work where thick coatings – up to 0.1 inch (2.5 mm) – are required. Smaller sized particles can be used to achieve a finer finish. Contact your Saint-Gobain Coating Solutions representative to determine the optimal thermal spray powder for your application.
#2000 Series Chromium Oxide Thermal Spray Powder
Saint-Gobain’s #2000 Series are fused black powders that feature rounded particles for superior flow characteristics. These powders produce dense, very hard coatings with excellent resistance to wear & corrosion.
These powders, which are backed by Saint-Gobain’s strict control of size & chemistry, deliver excellent deposit efficiencies with high build-up rates for reliable, economical application.
With virtually no chromium metal, these powders are ideal for laser engraving of printing rolls (anilox rolls) & other applications where components, such as pump parts & paper rolls, are exposed to corrosive environments.
Ruby Series of Chromia-Alumina Thermal Spray Powder
The Ruby series features a line of high-purity aluminum oxide-chromium oxide alloy powders that produce coatings with far superior properties than standard chromium oxides.
- High dielectric strength
- Good resistance to impact & wear
- Better release properties
- Excellent deposit efficiency
- Lower coating costs
The near-spherical morphology of RUBY powders ensures good flow properties for significantly faster build-up rates, which results in savings of both cost & time.
