Abrasive wear resistance of white cast iron can be improved by adding transition metals due to carbide formation and matrix stabilization. However, it must also be affected by carbon content which has received little attention from researchers. Therefore, this study would investigate the influence of (1.4 and 2.8 wt.%) C on three body abrasive wear characteristics of 28Cr-3Ni cast alloys. High Cr-based multi-component white cast irons (Hi–Cr MWCIs) were used as comparison materials to estimate the life-service of each material. The abrasion test was performed using a rubber wheel abrasion machine test with two different sizes of silica sands (1100HV1).

As results, the microstructure consists of martensite (the main matrix) and M₇C₃ carbide. Additionally, M₂C carbide was also precipitated on the microstructure of Hi–Cr MWCIs. Meanwhile, Ni or Co was embedded in the matrix area of materials microstructure. In the case of 28Cr-3Ni, the higher amount of C has a higher carbide volume fraction and hardness leading to be better abrasive wear resistance at high loads. However, the reverse trend occurred at low loads with different sizes of abrasive particles. By comparing to Hi–Cr MWCIs, its abrasive wear resistance is lower owing to the fewer carbide types. In the case of Hi–Cr MWCIs, the higher Cr addition significantly consumes C content during the solidification process resulting to lower hardness and wear resistance. Therefore, it can be concluded that the three abrasive wear performance of materials is strongly influenced by C content, applied load, and abrasive particle size.

由于碳化物形成和基体稳定，可以通过添加过渡金属来提高白口铸铁的耐磨性。然而，它也必须受到研究人员很少关注的碳含量的影响。因此，本研究将研究 (1.4 和 2.8 wt.%) C 对 28Cr-3Ni 铸造合金三体磨粒磨损特性的影响。高铬基多组分白口铸铁 (Hi-Cr MWCIs) 被用作比较材料，以估计每种材料的使用寿命。磨损试验采用橡胶轮磨损机试验，采用两种不同尺寸的硅砂（1100HV1）进行。

结果，显微组织由马氏体（主要基体）和 M ₇ C ₃碳化物组成。此外，M ₂C 碳化物也沉淀在 Hi-Cr MWCIs 的微观结构上。同时，Ni或Co嵌入材料微观结构的基体区域。在 28Cr-3Ni 的情况下，C 含量越高，碳化物体积分数和硬度越高，从而在高载荷下具有更好的耐磨性。然而，相反的趋势发生在具有不同尺寸磨料颗粒的低负载下。与 Hi-Cr MWCI 相比，由于碳化物类型较少，其耐磨性较低。在 Hi-Cr MWCI 的情况下，较高的 Cr 添加量会在凝固过程中显着消耗 C 含量，导致硬度和耐磨性降低。因此，可以得出结论，材料的三种磨料磨损性能受C含量、外加载荷和磨料粒度的强烈影响。
