Thermische Beschichtungszusammensetzung

摘要

An abrasive coating is prepared by plasma spraying a top coating over a bond coating medium. The resultant structure has an improved resistance to corrosion, and a lower thermal conductivity. The coating provides substantially enhanced engine efficiency and improved durability. The coating consists of from eleven to fourteen weight percent (11 to 14 wt.%) yttria and the balance essentially zirconia.
