Abstract
A simple history is ascribed to the liquid water in. the low-pressure stages of the steam turbine which accounts, in a semi-quantitative manner, for many of the observed facts concerning erosion of moving blades. It is shown that supersaturation causes precipitation of fine water drops away from surfaces and that probably only a small number of these drops are collected by blading through impact and diffusional processes. Erosion is believed to be caused by comparatively large drops torn from the blades and by water which has been centrifuged to and is travelling along the casing.
