Oxide Ceramic Powder
Cr2O3, Al2O3, Y2O3, YAG, 8YSZ and TiO2 ceramic powders for thermal spray coatings.
Oxide ceramic powders refer to a category of high-hardness, corrosion-resistant powder materials with metal oxides as the matrix. They are widely used in thermal spraying and plasma cladding processes, and can be applied to prepare ceramic coatings with wear resistance, corrosion resistance and electrical insulation properties.
Among them, chromium(III) oxide (Cr2O3) powder is one of the most extensively used oxide ceramic powders. It integrates excellent abrasive wear resistance, chemical corrosion resistance and electrical insulation performance, and is suitable for the surface protection of key components such as mechanical seals, valves and roller tables.
Our portfolio also includes alumina (Al2O3) variants, yttria (Y2O3), YAG, 8YSZ thermal barrier coatings and titanium oxide - covering applications from semiconductor processing equipment to aero-engine turbine blades.

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.
