Abstract: | An agglomerated Cr2O3/wt.%TiO2 powder has been fabricated by the spray drying process under different parameters. The spray-dried powder has well-agglomerated
particles of spherical shape. In the conditions of the high slurry feed rate and low binder concentration in the slurry, the
powder has large cavities inside some particles and ruggedness over their surface. The optimum plasma spray feed rate has
been found by examining the spraying behavior of the powder and melted state of particles. The plasma spray coating has been
performed under different process variables such as spraying distance and plasma power. These parameters strongly affect the
characteristics of the coated layer: microstructure, hardness, and bond strength. |
