Abstract

1290657 End face seals LEYLAND GAS TURBINES Ltd 1 June 1971 [26 June 1970] 31069/70 Heading F2B [Also in Division F4] A rubbing seal for engagement with a hot face of a matrix of a rotary thermal regenerator comprises a ferritic steel base member 1 and a rubbing surface layer 4 including nickel oxide. The base member is attached by welding or brazing to a metal bellows 2. In manufacturing the seal a bonding layer 3 of a nickel aluminium compound is first deposited on to the base member by flame deposition; the rubbing seal layer is then deposited on to the bonding layer 3 by flame deposition of a powder including nickel oxide. Preferably the powder comprises a mixture of nickel oxide and calcium carbonate, or a mixture of nickel oxide, metallic nickel and calcium carbonate.
