摘要：

We present the results of spectral, durametric, electron-microscope, and roentgenographic studies of water pump bearing face specimen microvolumes in contact with the sealing washer. It is shown that the process of destruction of the near-surface layers of the bearing face material is associated with the onset of tensile stresses due to significant increase of the hydrogen content in the hydridophylic zone. We identify the periodic nature of the change of the hydrogen concentration and the wear rate in time. We construct a mathematical model of the water pump bearing face hydrogen wear process; this model satisfactorily describes the experimental data.
