CORODUR® SP 229

Flux cored wires for Thermal Spray Application

EN ISO 14919 – 6 – 1,6 - 4

MATERIAL REVIEW

Very high bond strength, also on smooth surfaces, self-bonding due to exothermic reaction. Dense coatings with increased resistance against oxidation and high temperature corrosion up to 650°C. Can be applied on clean but not sand blasted surfaces. Best bonding if applied in one pass (about 0,125 mm). Designed for arc spraying but may also be sprayed by wire- and high-velocity-wire-flame-spraying.

APPLICATION

Bond coat for repair of gas turbines.
