Chromium Carbide-Based Powder Series
Cr3C2-NiCr powders for high-temperature wear, oxidation and erosion resistance.
Our chromium carbide-based thermal spray powders are engineered for high-temperature and corrosive service environments, with full compatibility with High-Velocity Oxygen Fuel (HVOF) spraying, plasma surfacing and laser cladding processes.
Led by the core grade Cr3C2-25NiCr, this series delivers exceptional high-temperature wear resistance, oxidation resistance and erosion resistance, maintaining stable long-term operation under coupled high-temperature and corrosive conditions.
It is extensively applied to metallurgical high-temperature rollers, power boiler tubes, aero-engine hot-end components and other high-demand high-temperature scenarios where conventional coatings degrade rapidly.

How to Specify & Apply
Identify the Service Envelope
Determine the dominant wear mode (abrasion, erosion, adhesion, corrosion, oxidation), operating temperature and impact load. This narrows the grade selection to 2-3 candidates.
Match the Process
Each grade is validated for specific deposition processes. The "Application Process" field above shows HVOF, HVAF, APS, PTA, LMD, OFS or CAW compatibility.
Choose the Particle Size
Particle size controls deposit density and surface finish. Fine cuts (15-30um) for thin dense coatings; coarser cuts (45-90um) for thick build-up and high deposition rate.
Request a Sample
Most grades ship with a 1-2 kg sample for in-house process qualification. Our engineers will support parameter development on your equipment.
