Summary

 
Object and purpose of research.This paper studies the samples made of powder materials using additive technologies. The purpose of this work was to study the effect of high-temperature oxidation and salt corrosion upon failure rate of this material
Subject matter and methodsThe paper investigates the changes in the rate of oxidation and salt corrosion reaction with the environment for four powder materials and nine cast alloys. The assessment is performed by comparison of these parameters for powder and cast alloys.
Main results.Oxidation and salt corrosion rates at the temperatures of 400–900°C for investigated powder and cast alloys practically coincided.
Conclusion.The study has shown that cast materials operating in marine atmosphere can be substituted by powder ones
