Paper Title:
Spherical Indentation on Glass-Coated Al2TiO5-Mullite Composites
  Abstract

A glass layer with high hardness and fatigue resistance is coated on the aluminum titanate (Al2TiO5) – mullite (3Al2O3⋅2SiO2) composites to improve wear and fatigue resistances. Mullite is added to aluminum titanate to constraint the decomposition of aluminum titanate and exhibit high mechanical strength as well as high elastic modulus. The aluminum titanate composites with various quasi-ductilities through controlling the contents of mullite in the substrate layers are prepared in this study. The results of the load-displacement curves and the resulting contact damages on the surface of glass coating layer by spherical indentation indicate that mullite addition and the glass coating is effective.
