Abstract

This study explores the feasibility of cladding CrFeNiAl_0.3Ti_0.3 and CrFeNiAl_0.3Ti_0.3–Ag high entropy alloys, produced via hot-press sintering (HPS), with commercial mild steel using the hot roll bonding (HRB) method. The bonding interface characteristics, mechanical properties, and tribological performance of these laminated composites were systematically evaluated. Microstructural analysis revealed that both high entropy alloys formed good metallurgical bonds with mild steel, exhibiting a straight interface free of visible cracks and oxidation products. Tribological investigations demonstrated that hot rolling significantly enhanced wear resistance, with specific wear rates decreasing by 70–82%. After hot rolling, the specific wear rate was reduced to (7.08–8.37) × 10^–5 mm³/Nm for CrFeNiAl_0.3Ti_0.3 and (6.12–7.05) × 10^–5 mm³/Nm for CrFeNiAl_0.3Ti_0.3–Ag across a temperature range from room temperature to 900 °C, compared to their pre-rolling values. These findings highlight the potential of hot roll bonding for integrating high entropy alloys with conventional materials, offering promising prospects for applications requiring high wear resistance and thermal stability.

高熵合金CrFeNiAl0.3Ti0.3和CrFeNiAl0.3Ti0.3 - ag与钢辊结合的磨损行为

本研究探讨了热压烧结（HPS）生产的CrFeNiAl0.3Ti0.3和CrFeNiAl0.3Ti0.3 - ag高熵合金与商业低碳钢采用热轧结合（HRB）方法熔覆的可行性。系统地评价了复合材料的结合界面特性、力学性能和摩擦学性能。显微组织分析表明，两种高熵合金均与低碳钢形成良好的金相结合，界面呈直线状，无明显的裂纹和氧化产物。摩擦学研究表明，热轧显著提高了耐磨性，比磨损率降低了70-82%。在室温至900℃的温度范围内，热轧后CrFeNiAl0.3Ti0.3的比磨损率降至（7.08-8.37）× 10-5 mm3/Nm, CrFeNiAl0.3Ti0.3 - ag的比磨损率降至（6.12-7.05）× 10-5 mm3/Nm。这些发现突出了热轧结合将高熵合金与传统材料集成的潜力，为需要高耐磨性和热稳定性的应用提供了广阔的前景。图形抽象
