Abstract

The issues of the process of hardening of parts made from steel 45 by a combined method were considered, which consisted in the application of coating by electric-arc metallization, subsequent lathe work, diamond surface smoothing and pulsed magnetic refinement. Parts that were hardened by a combined method were analyzed for durability. A pilot plant for the study of parts for durability resistance was described. The results of the research are presented. The nature of wearing of the component surfaces hardened by the combined method has been established. According to the test results, it was found that in the process of wear of component surfaces hardened by a combined electromechanical method no run-in occurred. The period of normal exploitation began immediately after the start of the work. The surface of the analyzed part after burnishing deformation by the diamond smoothing method works for a long period of time practically without abrasion. According to this, wear products do not enter the friction zone and cause abrasive wear. The destruction of the surface does not affect the entire surface simultaneously, it occurs in its individual sections. Other sections are only vulnerable to physico-chemical changes. Such partial destruction and changes features of the surface affect the interaction of the conjugate surfaces. Pulsed magnetic refining also increases the wear path by changing the physico-mechanical properties of the original material. The wear stages of coating surfaces hardened by diamond smoothing and pulsed magnetic refinement last longer.

用强化组合机电法研究零件表面的耐磨性

摘要

考虑了通过组合方法对由钢45制成的零件进行淬火处理的问题，这些问题包括通过电弧金属化施加涂层，随后的车床加工，金刚石表面平滑和脉冲磁精加工。分析通过组合方法硬化的零件的耐久性。描述了一个用于研究零件耐久性的中试工厂。介绍了研究结果。已经确定了通过组合方法硬化的部件表面的磨损性质。根据测试结果，发现在通过组合机电方法硬化的部件表面的磨损过程中没有发生磨合。正常的剥削期是在工作开始后立即开始的。用金刚石磨光方法进行抛光变形后，被分析零件的表面可以长时间工作，几乎没有磨损。据此，磨损产物不会进入摩擦区域并引起磨料磨损。表面的破坏不会同时影响整个表面，而是在其各个部分中发生。其他部分仅易受理化变化的影响。表面的这种部分破坏和变化特征影响共轭表面的相互作用。脉冲磁精炼还通过改变原始材料的物理机械性能来增加磨损路径。通过金刚石平滑和脉冲磁精加工硬化的涂层表面的磨损阶段持续更长的时间。
