Abstract
Corrosion problems on turbine blades in Italy are generally associated with the presence of chlorides in the steam. In some cases the scrubbing of the steam with alkaline solutions before is required. To overcome this problem, new materials for turbine blades were tested. Moreover, the presence of corrosion products (iron sulphides, etcc.) in the steam pipelines may cause some plugging in the turbine blading. This phenomenon is worsened when solid particles are present in the steam.
