Nitride-bonded silicon carbide is an alternative to steels resistant to abrasive wear. This paper presents the results of a nitride-bonded silicon carbide (SiC) wear test in diverse soil conditions. The test was performed on a "spinning bowl" test stand on three soil types: loamy sand, light loam and ordinary loam. The results were referred to the wear test for materials used to make parts working soil mass, i.e., abrasive wear-resistant steel, boron steel and C + Cr + Nb padding weld. The abrasive wear resistance of silicon carbide was shown to depend on the grain size distribution of the soil being worked. Silicon carbide showed the highest resistance in light soil. However, the padding weld showed higher wear resistance in the other soil conditions. Nitride-bonded silicon carbide had higher wear resistance than the steels under study in all of the soils. These findings are supplemented by an analysis of the condition of the worked surfaces after friction tests. The dominant wear methods in all abrasive masses were micro-cutting and furrowing.
氮化物结合碳化硅是耐磨损钢的一种替代品。本文介绍了在不同土壤条件下进行的氮化物结合碳化硅（SiC）磨损试验的结果。该试验在“旋转碗”试验台上对三种土壤类型进行：壤质砂土、轻壤土和普通壤土。试验结果与用于制造与土壤接触部件的材料的磨损试验结果进行了对比，即耐磨钢、硼钢和C + Cr + Nb堆焊。结果表明，碳化硅的耐磨性能取决于所处理土壤的粒度分布。碳化硅在轻质土壤中表现出最高的耐磨性。然而，堆焊在其他土壤条件下表现出更高的耐磨性。在所有土壤中，氮化物结合碳化硅的耐磨性均高于所研究的钢。通过对摩擦试验后工作表面状况的分析对这些发现进行了补充。在所有磨料中，主要的磨损方式是微切削和犁沟。
