[目的]研究Al含量对双相FeCoNiCrAlx熵合金(HEAs)涂层耐磨性的影响。[方法]采用激光粉末定向能量沉积(LPDED)技术在Q235钢表面制备了FeCoNiCrAlxx=0.5、0.7、1.0)涂层。研究了Al含量对FeCoNiCrAlx金涂层微观结构、显微硬度和耐磨性的影响。[结果]随着Al含量增大，FeCoNiCrAlx层的相结构从FCC(面心立方)单相转变为FCC+BCC(体心立方)双相，最终变成单一BCC相。Al含量的增大显著提升了FeCoNiCrAlx金涂层的显微硬度和耐磨性，这主要与BCC相的高本征硬度、Al元素诱导的晶格畸变强化效应及摩擦过程氧化膜的形成有关。[结论]通过调控Al含量可有效优化FeCoNiCrAlx层的相组成，当x=0.7时可获得FCC+BCC双相结构，赋予涂层高硬度和良好的耐磨性。
Abstract：[Objective] To study the effect of Al content on wear resistance of dual-phase FeCoNiCrAlxhigh-entropy alloy(HEA) coating. [Method] FeCoNiCrAlxx = 0.5, 0.7, 1.0) coatings were prepared on Q235 steel by laser powder directed energy deposition(LP-DED). The effect of Al content on the microstructure, microhardness, and wear resistance of FeCoNiCrAlxHEAs coatings was studied. [Result] With the increasing of Al content, the phase structure of FeCoNiCrAlxcoating evolved from single FCC(face-centered cubic) phase to FCC + BCC(body-centered cubic) dualphase, and ultimately transferred to single BCC phase. The increase in Al content significantly enhanced the microhardness and wear resistance of HEAs coatings, which was primarily attributed to the high intrinsic hardness of the BCC phase, the lattice distortion strengthening effect induced by Al, and the formation of a protective oxide film during friction. [Conclusion] The phase structure of FeCoNiCrAlxcoatings can be effectively optimized by adjusting the Al content. A dual-phase FCC+BCC structure is achieved when x is 0.7, endowing the FeCoNiCrAlxcoating with high hardness and excellent wear resistance.
