摘要
本文介绍了对涂层和氢氟碳化合物加热的中碳钢层进行局部硼化的技术过程。对不同形态硼化层磨损情况的比较研究表明，在 0.05 至 3 m/s 的滑动速度范围内，具有复合结构的硼化层具有优势。在恶劣的工作条件下，结合了紧凑结构和复合结构的硼化层可提供最长的有效保护时间。对硼化样本在恶劣条件下的磨损结果进行有条件的重新计算，可以假设楔形减震器在一般条件下的运行里程超过 60 万公里。
WEAR RESISTANCE OF COMPOSITE BORATED LAYERS OBTAINED BY HIGH FREQUENCY CURRENT (HFC) HEATING FOR HARDENING ROLLING STOCK PARTS
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.
