Introduction of a new generation thermal barrier coating for turbine nozzle guide vanes
Based on numerous experiments, the technology of application of the multilayer thermal barrier coating on the nozzle guide vanes and flame tubes of aircraft engines was developed at the enterprise. New coating has a heat-resistant metallic sublayer applied by HVOF method, and a ceramic upper layer applied by plasma method. The in-house developed control program enables the use of robotic system for application of all the layers. The conducted tests show that the service life of the coating can increase by 1.5 -2 times.
