Abstract: PROBLEM TO BE SOLVED: To provide a thick coating which can be used for a brush seal, has a long life and is free from crack. SOLUTION: This coating for a brush seal, in which a brush bristle is formed with a super alloy, has a nickel - chromium matrix which has a standard particle size of abut 44-15μm and contains a hard carbide phase of about 40-60vol% essentially made of a chromium carbide, and the nickel - chromium matrix contains, by nominal composition, about 80% Cr and about 20% Ni. The chromium carbide phase preferably and further contains either one of a titanium carbide, a tungsten carbide, a vanadium carbide and an optional mixture thereof.
