Conclusions

  1. 1.

    Gaseous erosion of specimens of titanium alloy VT8 causes a decrease of their fatigue limit by 6–8%. Subsequently, the fatigue limit does not decrease owing to changes in the surface layers of the specimens being worn. This phenomenon can be explained by the fact that during sufficiently long wearing the number of defects of the surface layer causing the appearance of fracture foci remains constant.

  2. 2.

    The decrease of the fatigue limit of machine parts, directly as a consequence of erosion, occurs during a time corresponding approximately to the first 20–100h of operation. During prolonged operation erosion can lead to a drop of the fatigue limit mainly due to changes of the size, shape, and vibrational characteristics of the machine parts being worn.
