Abstract：
This article presents the effect of the conditions of abrasive compounds on the wear of samples made by different methods. The 28MnB5 steel was used, which is intended for agricultural components, to which two arc and laser coatings were applied. The study included the analysis of microstructure, microhardness, roughness, and tribological experiments on a dedicated stand. The arc coating was found to significantly improve the tribological properties compared to the samples without the coating. Varied wear results were obtained for the laser coating depending on the parameters of the abrasive compound. Studies of the surface roughness of the samples showed that the concentration and pH of the abrasives have a significant effect on the changes in the surface parameters after the tribological tests. The results of the tribological experiments indicated that wear resistance for some of the abrasive mass conditions was improved by the application of heat-applied coatings. In addition, it was found that the power consumption on the stand was the highest for abrasive mass conditions of a 10% moisture content and a pH of 10. For these test conditions, the mass loss was four times higher than for the parameter with W0% and pH7. The energy consumption of the stand was 60 kWh lower for this variant than for the parameter with W10% and pH10. The results of the study have important practical applications that can help in the selection of materials for agricultural machinery components, depending on the abrasive mass conditions.
摘要：
本文介绍了磨料化合物的条件对通过不同方法制成的样品的磨损的影响。使用28MnB5钢，用于农业组件，对其施加了两种电弧和激光涂层。研究包括微观结构分析，显微硬度,粗糙度,和专用支架上的摩擦学实验。发现与没有涂层的样品相比，电弧涂层显着改善了摩擦学性能。根据磨料化合物的参数，激光涂层可获得不同的磨损结果。对样品表面粗糙度的研究表明，磨料的浓度和pH值对摩擦学测试后表面参数的变化有显着影响。摩擦学实验的结果表明，通过施加热涂涂层，某些磨料质量条件的耐磨性得到了改善。此外,发现对于10％水分含量和pH为10的磨料质量条件，支架上的功耗最高。对于这些测试条件，质量损失比W0%和pH7的参数高四倍。对于该变体，支架的能耗比具有W10％和pH10的参数低60kWh。研究结果具有重要的实际应用，可以帮助选择农业机械部件的材料，取决于磨料的质量条件。
