Reseña del editor: Excerpt from The Erosion of Steam Turbine Blades

Unlike the steam engine the steam turbine is not subject to much wear. In the steam turbine, practically the only weer is caused by the cutting action of the steam upon the blades. In most cases this wear is not serious, but it may cause an increase in the steam consumption.

In 1904 Mr. Francis Hodgkinson presented a paper before The American Society of Mechanical Engineers, in which he gave the results of some experiments concerning the erosion of steam turbine blades. In these experiments hard drawn Delta metal blades were exposed to the action of steam for 128 hours. Two nozzles were used with velocities of approximately 2900 feet per second and 600 feet per second, the wear being much greater in the case of the high velocity than with the low velocity.
