摘要

本文研究了锡青铜和碳化铬混合粉末预涂层等离子体加热时表面合金层的特性和耐磨性。已经确定，根据混合物的组成、涂层的厚度、加工方式的不同，所得到的层在结构、化学成分和相组成上是不同的。加入质量分数为20%的碳化铬，可以使锡青铜合金层的显微硬度提高到700 HV，形成马氏体结构。磨料磨损试验分别在5、20、50牛的载荷下进行，并使磨料夹与砂轮同向旋转。结果表明，Fe-Cu-Sn和Fe-Cr-C-Cu-Sn合金层的耐磨性高于Cu-Sn合金层。其中Fe-Cr-C-Cu-Sn层效果最好。©2022由工程学院出版

Characteristics and Abrasive Wear Resistance of Plasma Alloyed Layers Based on Tin Bronze and Chromium Carbide

This paper presents a study of the characteristics and resistance to abrasive wear of surface alloyed layers during plasma heating of powder pre-coating of a mixture containing tin bronze and chromium carbide. It has been established that, depending on the composition of the mixture, the thickness of the coating, the processing mode, the resulting layers differ in structure, chemical and phase composition. The addition of chromium carbide with a mass fraction of 20% makes it possible to increase the microhardness of the alloyed layer based on tin bronze up to 700 HV with the formation of a martensitic structure. Tests for abrasive wear were carried out at a load of 5, 20, 50 N and with codirectional rotation of the holder to the abrasive wheel. The obtained results showed that the wear resistance of the Fe-Cu-Sn and Fe-Cr-C-Cu-Sn alloyed layers is higher compared to the Cu-Sn layer. In particular, the Fe-Cr-C-Cu-Sn layer is the best. © 2022 Published by Faculty of Engineering
