Cr2O3-25TiO2 Powder

$23.00

Thermal spray coatings of pure chromia (chromium oxide, Cr2O3) possess high hardness, abrasion and corrosion resistance. However, these coatings are also often associated with high brittleness. The addition of TiO2 (titanium dioxide) provides ductility and promotes coatings that are denser and smoother than those of pure chromia.

Cr2O3-25TiO2 powder is a Cr2O3 25 wt.% TiO2 powder that produces coatings characterized by very good resistance against abrasion, heat and corrosion combined with very good fracture toughness for a ceramic coating.
