Sprayable Nanostructured Alumina / Titania S2613P Nanox™ Powder


Thermal Spray Grade Plasma Densified

Alumina/Titania is a ceramic composite material used as a wear resistant coating for machine components.
Nanox™ S2613P feedstock powder is agglomerated nanoparticles with high density and flowability and an average diameter of 30 µm.

Wear Characteristics

SEM studies of wear surfaces reveal a morphology difference between coatings sprayed with conventional versus nanostructured alumina/titania. The wear tracks on conventional coatings are rough (grooves, deformation and microfracture), whereas the wear surfaces on nanostructured alumina/titania coatings are relatively smooth (no grooves, deformation or microfracture). Wear resistance is related to toughness, microhardness, and microstructure. Toughness of nanostructured alumina/titania improves the wear resistance of the coatings. Full spray specifications are available through Technical Applications Bulletin No. S2613P.01.A.\
