Abstract

Contains information about the composition, properties, purpose, effectiveness glass-enamel coating for protection of cast parts hot tract of gas turbine engines of iron-nickel alloys, from high-temperature gas corrosion. The coating retains its high temperature resistance, head-resistance, durability of cou-pling in the process of multistage heat treatment: hardening at temperature 1120°C – 3 hours, aging at 750°C – 15 hours, and during operation at temperature of 700 to 900°C, which reduces the oxidation of alloys in 25–30 times.
