Testing Indicates Coating Can Extend the Life of Steam Turbine Blades
Preliminary tests indicate that Hardide nanostructured chemical vapor deposition (CVD) coating can extend the life of steam turbine blades through significantly enhanced resistance to water droplet erosion (WDE) and solid particle erosion.
The tests, carried out by the National Physical Laboratory (NPL) and the University of Manchester (UoM), assessed the effectiveness of the Hardide coating as protection from WDE and cracking on FV520B last stage turbine blades.
