This article presents the results of abrasion wear resistance tests of wear-resistant steel and surfacing under laboratory conditions and natural operation. Abrasion wear resistance determined on the basis of the study by determining geometrical characteristics of the alloying additives using computer image analysis methods, as well as examining the changes occurring on the surface of the workpieces and their wear intensity. Based on the results obtained from laboratory tests, it was noted that AR steel exhibited 14 times greater wear than the padding weld. This wear is affected by alloy additives, which, for the padding weld, are chromium additives. The microstructure image shows that soil mass had a destructive effect mainly on the matrix of the material, whereas in the areas with high concentrations of chromium precipitates, this effect was significantly weaker. The operational test results showed that within the area of the tine subjected to hardfacing, the material loss was lower than that for the same area of the tine in the as-delivered state. For the hardfaced tine, a 7% loss of volume was noted in relation to the operating part before testing and following the friction process. However, for the operating part in the as-delivered state, this difference amounted to 12%.
本文介绍了耐磨钢及其堆焊层在实验室条件和实际运行情况下的耐磨耗试验结果。通过使用计算机图像分析方法确定合金添加剂的几何特征，并检查工件表面发生的变化及其磨损强度，基于该研究确定了耐磨性能。根据实验室测试获得的结果，发现耐磨钢的磨损比堆焊焊缝大14倍。这种磨损受到合金添加剂的影响，对于堆焊焊缝而言，合金添加剂为铬添加剂。微观结构图像显示，土壤对材料基体有主要的破坏作用，而在铬沉淀物浓度较高的区域，这种作用明显较弱。运行测试结果表明，在堆焊的齿区域内，材料损失低于交付状态下相同齿区域的损失。对于堆焊齿，在测试前和摩擦过程后的运行部件中，体积损失为7%。然而，对于交付状态下的运行部件，这一差异为12%。
