摘要：
In this paper, air plasma spray Al2O3-13% TiO2 coatings were produced by two type of feedstock powders (agglomerated nanostructured and conventional). Mechanical properties of coatings including hardness, toughness, fatigue, and wear behavior as well as grindability of coatings were evaluated and compared. We report that due to the presence of nanostructure zone in microstructure of air plasma sprayed Al2O3-13% TiO2 nanostructure coatings, a significant gain is observed in toughness, grindability, and fatigue lifetime in nanostructure coating over its counterpart conventional coating.
