Blade tip with cutting surface layer

The stripper lining has a run-up lining (3) made from a thermally injected ceramics layer profiled so that its has cutting edges with interspaces inbetween to collect up the abrasions from the inlet lining. The stripper lining is made from ZrO27Y2O3. The metal engine component can be the bucket vane...

Beschreibung
Zusammenfassung:	The stripper lining has a run-up lining (3) made from a thermally injected ceramics layer profiled so that its has cutting edges with interspaces inbetween to collect up the abrasions from the inlet lining. The stripper lining is made from ZrO27Y2O3. The metal engine component can be the bucket vane tip of an engine paddle. It can be a sealing tip of a labyrinth seal. When making the lining a perforated mask is placed on the component surface being coated. The ceramic material is thermally sprayed through the mask onto the surface at a spray angle of 10 to 30 degs. to form the cutting edges and interspaces. The component surface can be profile-etched.
