Abstract
Blended thermal spray powders are characterized by the presence of a ZrO.sub.2 component and a ceramic coated plastic component. The ceramic coated plastic component is made by attrition milling ceramic fine particles with plastic core particles, causing the ceramic fine particles to bind to the surface of the plastic core without the use of a binder. Abradable coatings formed by thermal spraying the powders have superior high-temperature properties such as heat resistance and yet abrade readily to form abradable seals.
