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.
