A low-pressure turbine is provided with stationary and rotating blades, and the blades have a coating that is hydrophobic or water-repellant and has a smooth surface. The coating preferably contains amorphous carbon. The hydrophobic property of the coating has the result that small droplets contained in the steam phase, upon impacting a coated blade, roll off across the blade in the form of small droplets and further follow the steam path. This prevents moisture losses and increases the efficiency of the turbine. It also prevents the small droplets on the blades from coalescing into larger droplets or into a fluid film. This prevents droplet impingement erosion caused by the impact of large droplets on the blading and other components of the turbine.
