Ti和C元素对AlCu(NiCr)2Mo高熵合金熔覆层组织与性能的影响
|
Abstract:
采用TIG电弧熔覆技术和旁轴送丝的方式，在45#钢基体表面制备了AlCu(NiCr)2MoX (X = Ti、C、Ti和C)高熵合金熔覆层，探究了Ti和C元素分别加入和同时加入对AlCu(NiCr)2Mo高熵合金组织与性能的影响。结果表明：AlCu(NiCr)2Mo高熵合金熔覆层组织由面心立方结构(FCC)的单一固溶体相组成。Ti和C元素分别加入后，熔覆层组织由FCC + BCC相组成，FCC相的主衍射峰位置基本没变，但其衍射峰强度降低，与此同时，熔覆层的磨损率相比AlCu(NiCr)2Mo高熵合金减少了97.43%，平均显微硬度提高至687.81 HV0.2和543.08 HV0.2。Ti和C元素同时加入，熔覆层组织由FCC + BCC + TiC相组成，熔覆层的磨损率相比AlCu(NiCr)2Mo高熵合金减少了98.53%，平均显微硬度提高至388.26 HV0.2。
AlCu(NiCr)2MoX (X = Ti, C, Ti and C) high-entropy alloy coatings were prepared on the surface of 45# steel substrate by TIG arc cladding technology and side-axis wire feeding. The effects of Ti and C elements on the microstructure and properties of AlCu(NiCr)2Mo high-entropy alloy were investigated. The results show that the microstructure of AlCu(NiCr)2Mo high-entropy alloy coating is composed of a single solid solution phase with face-centered cubic structure (FCC). After the addition of Ti and C elements, the coating structure is composed of FCC + BCC phase. The main diffraction peak position of the FCC phase is basically unchanged, but the diffraction peak intensity is reduced. At the same time, the wear rate of the coating is 97.43% lower than that of the AlCu(NiCr)2Mo high-entropy alloy, and the average microhardness is increased to 687.81 HV0.2 and 543.08 HV0.2. Ti and C elements are added at the same time, and the coating structure is composed of FCC + BCC + TiC phase. The wear rate of the coating is 98.53% lower than that of AlCu(NiCr)2Mo high-entropy alloy, and the average microhardness is increased to 388.26 HV0.2.
