Thermal Spraying Powders

Thermal Spraying Powders

SAM is a leading supplier of both advanced raw materials for the production of thermal spray powders, and of ready-to-spray powders for a number of specialty applications. Our main products include:

Raw materials for making thermal spray powders

• Rare-earth oxides for stabilized zirconias used in thermal barrier coatings (TBCs), e.g. yttrium oxide (Y2O3), ytterbium oxide (Yb2O3), gadolinium oxide (Gd2O3), dysprosium oxide (Dy2O3)
• High purity (5N) yttrium oxide for the semiconductor industry
Hafnium oxide (HfO2)
Yttrium metal for MCrAlY bond coats
Chromium carbides (Cr2C3) for corrosion resistance, tungsten carbides (WC) for wear resistance
• Special non-oxides e.g. titanium boride (TiB2), zirconium boride (ZrB2), chromium nitride (CrN2)

Ready-to-spray powders

• Substoichiometric oxides e.g. TiOx
• YSZ suspensions and other zirconia-based suspensions for Suspension Plasma Spraying (SPS)
• Fused and crushed YSZ
• Rare-earth silicates for environmental barrier coatings (EBCs)
• Specially mixed oxides: LSM, LSCF
