摘要： A chamber component comprises a body and a plasma sprayed ceramic coating on the body. The plasma sprayed ceramic coating is applied using a method that includes feeding powder comprising a yttrium oxide containing solid solution into a plasma spraying system, wherein the powder comprises a majority of donut-shaped particles, each of the donut-shaped particles having a spherical body with indentations on opposite sides of the spherical body. The method further includes plasma spray coating the body to apply a ceramic coating onto the body, wherein the ceramic coating comprises the yttrium oxide containing solid solution, wherein the donut-shaped particles cause the ceramic coating to have an improved morphology and a decreased porosity as compared to powder particles of other shapes, wherein the improved surface morphology comprises a reduced amount of surface nodules.

摘要： An anti-electrolytic corrosion rolling bearing includes an inner ring and an outer ring, rolling elements, and a thermal-sprayed ceramic film having electrical insulating properties, and disposed on one or each of the inner peripheral surface of the inner ring and the outer peripheral surface of the outer ring. The thermal-spray material forming the thermal-sprayed ceramic film contains, as the main component thereof, alumina particles having particle sizes of 5 μm to 60 μm and an average particle size of 30 μm to 60 μm. The thermal-sprayed ceramic film is densified by filling the pores between the alumina particles, with a predetermined amount of glassy melts of a metal oxide having a melting point lower than that of the alumina, such as silica, yttria, titania or zirconia, and having an average particle size of 5 μm to 40 μm.

摘要： A method for forming a vertically cracked thermal barrier coating is disclosed including positioning an article relative to a heat source. The article includes a thermal barrier coating disposed on a first surface of a substrate, and the substrate includes a second surface distal across the substrate from the first surface. Heat is applied locally to at least one discrete portion of the second surface of the substrate. At least one vertical crack in the thermal barrier coating is formed disposed over the at least one discrete portion. An article is disclosed including a substrate and a vertically-cracked thermal barrier coating disposed on the substrate. The vertically cracked thermal barrier coating includes at least one vertical crack in the thermal barrier coating and at least one of a low density of less than 85% of a theoretical density for the thermal barrier coating and a selective crack distribution.
