Структура и свойства термобарьерных покрытий, полученных различными способами

Abstract

spray barrier coating and electric arc physical vapor deposition barrier coating, for which the initial state and after the long-term operation were evaluated. In the work process the theory of the coatings at high temperatures, the base material of Nickel superalloy, the deposition methods and the analysis methods for the coatings evaluation are used. In the work result the evaluation of each type of coatings system in its initial and final state is presented after being subjected to the operation. The work effectiveness concludes that the thermal barrier coating system generated by the electric arc physical vapor deposition method, is more effective in protecting the superalloy ZhS6F at high temperature conditions.
