HIGH TEMPERATURE METAL ALLOY MIXTURES FOR FILLING HOLES AND REPAIRING DAMAGES IN SUPERALLOY BODIES

摘要

the mixture of metallic powder and is suitable for filling holes in silicon, cracks and joints with large gaps in high temperature alloys and / or recovery and extension of reforming areas damaged or missing, and it may be (e) at a temperature of about 2000u00b0f.semi solid metal mixture has a viscosity surface tension and high enough to be essentially non flowing at the processing temperature so that it keeps its shape and its point of application without sinking during the treatment. the metal mixture, after treatment, has a solidus temperature of at least 1900u00b0f.
