這裡所說的plasma spraying可能就是指涂层

Method for producing an abradable seal
Document Type and Number: United States Patent 5780116
Link to this Page: http://www.freepatentsonline.com/5780116.html
Abstract: A gas turbine abradable seal is prepared by

an oxidation resistant metallic material and boron nitride. The resultant structure comprises a metallic matrix encompassing a lubricating amount of boron nitride, with porosity of less than about 15 percent and a fabricated surface roughness of less than about 600 microinches. The reduced surface roughness and substantially reduced permeability of this seal provide substantially enhanced engine efficiency, and improved durability.

可磨耗密封装置
本想答成：可磨耗密封涂层，但既然chance排除了“涂层”的可能性，只好按seal的本意（密封装置；密封垫）来解释。
