Abrasion Resistance of Alumina-Titanium Dioxid Coating at High Temperature

Abstract:

Nano-structured and micron Al2O3-13%TiO2 coatings were deposited by air plasma spraying.Wear properties of the coatings under different temperature trough SRV friction and wear testing machine were studied, the results shows that the friction coefficient of nano and micron Al2O3-13%TiO2 coatings both have rising trend.with the temperature increases.The wear volume of micron coating is 1.8-2 times that of the nano coating..The nanometer Al2O3-13%TiO2 coating slide with ZrO2 is still compact and has no large crack after abrasion.
