摘要

本文介绍了0.34Cr-1Ni-Mo-Fe钢表面硬化电解等离子体处理过程的研究结果，以及阴极电解等离子体处理的电流-电压特性随电解液成分的变化结果。测定了0.34Cr-1Ni-Mo-Fe钢电解等离子淬火的温度、时间和特殊方式。已经确定了用于电解等离子体硬化的电解质的最佳组成，提供了相对高的加热速率和钢表面的高硬度。结果表明，34KhN1M钢在电解等离子淬火后，由于形成了细小的马氏体，显微硬度提高了2.9倍。在这种情况下，材料的基础不会改变，它由铁素体-珠光体结构组成。

Influence of electrolytic-plasma hardening modes on structure and hardness of 0.34Cr-1Ni-Mo-Fe steel

The article presents the results of studying the process of electrolytic-plasma hardening of 0.34Cr-1Ni-Mo-Fe steel by surface hardening, as well as the results of the current-voltage characteristics of the cathodic electrolytic-plasma process depending on the composition of the electrolyte. Temperature-time and special modes of electrolytic-plasma hardening of steel 0.34Cr-1Ni-Mo-Fe were determined. The optimal composition of the electrolyte for electrolytic-plasma hardening has been determined, providing a relatively high heating rate and high hardness of the steel surface. It has been determined that after the electrolytic-plasma hardening, the microhardness of 34KhN1M steel increases 2.9 times due to the formation of fine martensite. In this case, the basis of the material does not change, it consists of a ferrite-pearlite structure.
