AbstractThe hardness and microstructure of as-deposited and annealed Cr-Zr-O coatings have been comparatively investigated to clarify the effects of annealing treatment. The as-deposited coating comprises of nano-sized columnar grains of (Cr, Zr)(2)O-3 that is formed due to the solution of Zr atoms in Cr2O3. Such a kind of structure is benefit for the hardness. The interface between the as-deposited coating and substrate is well-bonded and a sandwiched structure forms during the deposition process. After annealing at 800 degrees C, a high density of nanosized voids were formed in the coating. The sandwiched structure at the interface is damaged and the bonding of interface becomes weak. As a result, the modulus and hardness of the Cr-Zr-O coating decrease significantly after annealing.
