摘要

硬化金属的现代有效方法之一是在氨或无水介质(氮气+氩气)中进行辉光放电氮化。本文介绍了实验研究的结果,比较了通过自主和互连BATR模式氮化获得的硬化表面的摩擦学和物理化学性能的结果。传统上固定的操作参数值(温度、气体混合物的组成、压力和饱和时间)的复杂性,而不考虑能量特性(电压、电流密度和比放电功率),大大降低了BATR实现金属表面必要物理化学性质的技术能力条件开采。考虑到BATR的能量特性,实现了氮化过程能耗的显著降低。主要子过程的能级显著不同:氮化物的形成发生在低能量下,表面溅射发生在高电压值下,氮扩散发生在增加的电流密度值下。在流的能量不足的情况下,可能根本不会发生辉光放电,或者在缺乏电压的条件下,表面上的氮化物球没有被喷涂,它充当了阻止扩散过程进入金属内层的屏障,这导致氮化球的物理化学指标和相应的摩擦学指标较低。只有通过BATR的能量和操作特性的独立组合,才能分别实现它们之间的定量比率和金属所需的操作特性

Influence of the parameters of hydrogen nitrogen nitrogen in a glow discharge on tribological and physico-chemical properties of steel 40X
One of the modern and effective methods of hardening metals is nitriding in a glow discharge in ammonia or in an anhydrous medium (nitrogen + argon) - BATR. This paper presents the results of experimental studies comparing the results of tribological and physicochemical properties of hardened surfaces obtained by nitriding with autonomous and interconnected BATR modes. The complex of traditionally fixed values of operating parameters (temperature, composition of the gas mixture, pressure and saturation time) without taking into account energy characteristics (voltage, current density and specific discharge power) significantly reduces the technological capabilities of BATR to achieve the necessary physicochemical properties of metal surfaces specified by conditions exploitation. Taking into account the energy characteristics of BATR, a significant reduction in the energy consumption of the nitriding process is achieved. The energy levels of the main subprocesses are significantly different: the formation of nitrides occurs at low energies, surface sputtering occurs at high voltage values, and nitrogen diffusion occurs at increased current density values. In cases where the energy of the flow is insufficient, either a glow discharge may not occur at all, or with a lack of voltage, the nitride ball on the surface is not sprayed and it acts as a barrier that prevents the diffusion process into the inner layers of the metal, which leads to low physicochemical and, correspondingly, tribological indicators of nitrided balls. The quantitative ratio between them and the required operational properties of the metal, respectively, can be achieved only through an independent combination of the energy and operating characteristics of BATR
