During operation, parts of the high temperature section of land-based gas turbine units are subjected to an aggressive gas environment, which affects adversely the durability of components and assemblies. When analyzing operational fractures of the ZhS32-VI alloy blade roots after operation as parts of land-based gas turbines, we found that cracks developed in the places of active sulfide-oxide corrosion. In this paper, it is shown that the presence of silver accelerates the corrosion of turbine blade roots. It is proposed to use TiN-based technological barrier layers to protect the blade root surfaces from sulfide-oxide corrosion. [ABSTRACT FROM AUTHOR] |
