摘要/Abstract

摘要： 使用激光熔覆技术在Q235钢基体上制备Al_xNbMn₂FeMoTi_0.5高熵合金涂层,期望借此提高干切削技术适用刀具表层的硬度和耐磨性。经过初步筛选之后,主要研究了Al_xNbMn₂FeMoTi_0.5(x=1、1.5、2)高熵合金涂层体系,并采用XRD和3D激光扫描成像等手段分析了不同Al含量的Al_xNbMn₂FeMoTi_0.5合金涂层的晶相结构、显微组织和具体元素分布。结果显示,对于Al_xNbMn₂FeMoTi_0.5高熵合金涂层,随着Al含量的增加,涂层的相结构由单一的BCC相逐渐转变为双相BCC结构,晶粒逐渐细化。当x=2时,Al_xNbMn₂FeMoTi_0.5高熵合金涂层硬度最高,平均为1089.6 HV0.3,大约为基材的5倍,且其具有最优的耐磨损性能。x=1.5时,Al_xNbMn₂FeMoTi_0.5高熵合金涂层的自腐蚀电位最高,自腐蚀电流密度最小,耐腐蚀性最好。

Abstract: Laser cladding technology was used to prepare the Al_xNbMn₂FeMoTi_0.5 high-entropy alloy coatings on the Q235 steel substrate. It was expected to improve the hardness and the wear resistance of the surface layer of cutting tool suitable for dry cutting technology. After preliminary selecting, the Al_xNbMn₂FeMoTi_0.5 (x=1,1.5,2) high-entropy alloy coating system was mainly studied, and the phase structure, microstructure and specific element distribution of the Al_xNbMn₂FeMoTi_0.5 alloy coatings with different Al content were analyzed by means of XRD and 3D laser scanning imaging. The results show that for the Al_xNbMn₂FeMoTi_0.5 high-entropy alloy coatings, with the continuous addition of Al, the phase structure of the coating gradually evolves from a single BCC phase to a dual-phase BCC structure, and the grains are gradually refined. When x=2, the Al_xNbMn₂FeMoTi_0.5 high-entropy alloy coating reaches the highest hardness, with an average of 1089.6 HV0.3, which is about 5 times of that of the base material, and it has the best wear performance.When x=1.5, the Al_xNbMn₂FeMoTi_0.5 high-entropy alloy coating reaches the highest self corrosion potential and the lowest self corrosion current density, and has the best corrosion resistance.

Key words: high-entropy alloy, laser cladding, coating, microstructure, hardness, wear resistance, corrosion resistance
