Spherical Chromium Oxide Powder, Cr₂O₃ Thermal Spray Powder, Plasma Spray Powder, HVOF (High-Velocity Oxy-Fuel) Spray Powder; features high sphericity, excellent flowability, high hardness, wear and corrosion resistance, and produces low-porosity coatings.
This spherical chromium oxide thermal spray powder offers high sphericity and stable flowability, ensuring smooth powder feeding. Coatings produced with this material are characterized by high hardness, a dense structure, and excellent resistance to wear, erosion, and corrosion (including resistance to acids, alkalis, and solvents). It is compatible with both plasma spraying and HVOF (High-Velocity Oxy-Fuel) processes, making it a classic ceramic material for industrial wear-resistant and anti-corrosion applications.
Based on chromium(III) oxide (Cr₂O₃), this ceramic thermal spray powder undergoes a spheroidization process, resulting in rounded particle morphology and uniform apparent density. This ensures consistent powder delivery without clogging the spray gun. The resulting coatings are highly hard and dense, offering superior resistance to wear, erosion, and chemical attack (acids, alkalis, and solvents), as well as a low coefficient of friction. It is widely used for surface protection on components such as plungers, valves, shafts, papermaking rollers, chemical processing equipment, and mechanical seals, effectively extending the service life of these parts. Suitable for applications such as mechanical seal rings, paper mill rolls, chemical valves and fittings, hydraulic plungers, metallurgical rollers, textile godet rolls, aerospace wear parts, and power plant anti-erosion components; also used for shaft repair. Compatible with HVOF (High-Velocity Oxy-Fuel) and plasma spray coating processes.
