Abstract:
An improved abradable coating particularly useful to control clearances between relatively moving members in a sealing relationship includes a base portion and an abradable coating portion which is the fusion and interaction product of a mechanical mixture of a plurality of powdered materials comprising a nickel-graphite powder and a nickel-chromium-base alloy powder. One method for making such a seal member includes applying a strippable bond coat of predominantly nickel between a base portion of the member and a subsequently thermal deposited coating.
