Abstract
The paper presents the technological process of local borating of medium carbon steellayers from coatings and HFC heating. Comparative studies of the wear of borated layers with different morphologies show the advantages of layers with a composite structure in a wide range of sliding speeds from 0.05 to 3 m/s. The maximum effective protection time is provided by borated layers which combine a compact structure with a composite one under harsh operating conditions. Conditional recalculation of the wear results of borated samples in harsh conditions allows assuming that running of the wedge-type shock absorber in general conditions is more than 600 thousand km.
