Abstract

This article describes the structure and properties of the developed hybrid composite Hastelloy X (NiCrFeMo)-AlMoNbTaTiZr-cBNSiCNiAlCo. The composite was obtained by the high velocity oxygen fuel spraying (HVOF) method in a protective atmosphere with a subsequent high-temperature thermomechanical treatment. In order to obtain new information about the structure, we studied the metallophysical properties of the composite using electron microscopy and X-ray diffraction analysis, as well as the mechanical properties and phase composition. We studied the influence of high-energy mechanical processing of high-entropic and ceramic materials on the structural-phase state and composite quality. We determined the optimal technological parameters of HVOF in a protective atmosphere, followed by a high-temperature thermomechanical treatment. Additionally, we optimized these parameters to form a hybrid composite providing the highest adhesion and low porosity. Moreover, we investigated the microhardness of the composite layers. On the basis of complex metallophysical studies, we examined the composite formation. In order to determine the endurance limit in comparison to various other composite materials, we carried out cyclic endurance tests of the developed materials.

研究石油和天然气工业中复合材料的结构和力学性能
本文介绍了研制的哈氏合金X (NiCrFeMo)-AlMoNbTaTiZr-cBNSiCNiAlCo复合材料的结构和性能。在保护气氛下采用高速氧燃料喷涂(HVOF)法制备复合材料,并进行高温热处理。为了获得新的结构信息,我们利用电子显微镜和x射线衍射分析研究了复合材料的金相物理性能,以及力学性能和相组成。研究了高熵陶瓷材料的高能机械加工对结构相态和复合材料质量的影响。在保护气氛下确定了HVOF的最佳工艺参数,并对其进行了高温热处理。此外,我们优化了这些参数,形成了具有最高附着力和低孔隙率的混合复合材料。此外,我们还研究了复合材料层的显微硬度。在复杂金属物理研究的基础上,对复合地层进行了鉴定。为了确定与其他各种复合材料相比的耐久性极限,我们对所开发的材料进行了循环耐久性试验。
