Abstract
A method of depositing an anti-wear coating on a mechanical part by thermal spraying of the AC-HVAF type, said coating being made of a copper-based alloy containing 30% to 42% by weight of nickel and 4% to 6% by weight of indium.
Claims
exact text as granted — not AI-modified1 . A method of depositing an alloy of copper, nickel, and indium by thermal spraying to constitute an anti-wear coating on a mechanical part, wherein said coating is deposited by thermal spraying of the AC-HVAF type.
2 . A method according to claim 1 , wherein said coating is a copper-based alloy containing 30% to 42% by weight of nickel and 2% to 8% by weight of indium.
3 . A method according to claim 2 , wherein said coating is a copper-based alloy containing 34% to 38% by weight of nickel and 4% to 6% by weight of indium.
4 . A method according to claim 3 , wherein said coating is a copper-based alloy containing 36% by weight of nickel and 5% by weight of indium.
5 . A method according to claim 1 , wherein said mechanical part for coating is a part made of titanium or titanium alloy.
6 . A method according to claim 1 , wherein said coating is deposited on at least one part taken from two parts of a gas turbine that are liable to come into contact with each other.
7 . A method according to claim 1 , wherein said coating is deposited on a fan or compressor blade root of a turbomachine, and/or the fan or compressor disk in which said blade root is engaged.Join the waitlist — get patent alerts
