Brazing construction for abradable sealing material used in turbine, includes infiltration prevention agent which is filled on non-brazing side upto specific depth so as to restrict infiltration of brazing filler metals

摘要

The abradable sealing material fixed on the base (10), consists of honeycomb seal formed by resin sheets (2). The base is divided into cellular sections having empty sections and partitions such that gap between base and rotating object is sealed. Infiltration prevention agent is filled on the non0-braze side upto specific depth so as to restrict the infiltration of brazing filler metals (7). - An INDEPENDENT CLAIM is also included for brazing method of abradable sealing material.
