Abstract

Cobalt-based functional gradient coating was prepared on alumina ceramic by microwave sintered with Co-based self-fluxing alloy powder and alumina ceramic powder as raw materials.Effects of different powder ball-milling time and sintering temperature on microstructure and bonding interface of coating were investigated

and relative density of the coating was measured.The results reveal that after balling for 24hours

the coating prepared at 1 300℃possesses homogeneous microstructure and desirable bonding interface as well as high relative density.
