Abstract

The special features of thick combined electrospark coatings (СESC) formed on cylindrical 12Kh18N10T stainless steel samples are analyzed. The samples were carbonized with the help of combined electrospark alloying (CЕSA) using an Elitron-52A device and aluminized with the help of electrospark alloying (ESA) using an EIL-9 automated device at a discharge energy of W_d = 3.4 J. The coatings were deposited on the aluminized surfaces with the help of the T15K6 hard alloy using the same device at W_d = 0.9 and 3.4 J. The СESC roughness was reduced by means of ball rolling and applying a metal–polymer material (MPM) reinforced with the VK6 hard-alloy powder. A new technology to recover parts, such as rotation bodies, has been proposed for practical applications. It made it possible to form the СESC on 12Kh18N10T steel in the following sequence: CЕSA → ESA Al → ESA T15K6 → MPM (reinforced with VK6), with a thickness up to 1.5 mm, a continuity of 100%, a microhardness of ∼10 100–9500 MPa, and a roughness of R_a = 1.2 μm.

基于电火花合金化的组合技术在12Kh18N10T钢旋转体部件表面形成耐磨涂层时提高生态安全性

摘要

分析了在圆柱形12Kh18N10T不锈钢样品上形成的厚组合电火花涂层（СESC）的特点。使用Elitron-52A装置通过组合电火花合金化（CÅSA）将样品碳化，并使用EIL-9自动装置通过电火花合金化（ESA）铝化，放电能量W _d = 3.4 J.使用相同的装置在W _d的帮助下，在T15K6硬质合金的帮助下，将涂层沉积在镀铝表面上。= 0.9和3.4J。通过滚球和使用VK6硬质合金粉末增强的金属聚合物材料（MPM）可以降低СESC粗糙度。已经提出了一种用于实际应用的回收零件（例如旋转体）的新技术。这样就可以按以下顺序在12Kh18N10T钢上形成СESC：CЕSA→ESA Al→ESA T15K6→MPM（用VK6增强），厚度最大为1.5 mm，连续性为100％，显微硬度为〜10 100–9500 MPa，粗糙度R _a = 1.2μm。
