过渡金属碳化物 (TMC) 的重要应用是作为通过等离子转移弧焊 (PTAW) 和激光方法沉积的耐磨复合层。在增材制造和 HEA 技术（大块复合材料和层）以及能量转换和存储领域，人们对它们的兴趣也越来越大。本文介绍了对元素周期表中两个边界 IVB 和 VIB TM 基团的 NiBSi-TMCs 系统界面相互作用的比较研究结果。进行了模型（润湿性和铺展性）和应用实验（PTAW 获得的碳化物颗粒-基体边界的测试）。来自部分熔化的钢基材的 Fe 在液态 NiBSi-TMCs 系统中是活跃的。结果表明，TMCs与液态NiBSi基体的相互作用随着组数的增加而增加，并且在各个组内从上到下。IVB TMC 的颗粒通过液体沿晶界渗透而分解，而 VIB 的颗粒通过在基体中的溶解度和二次结晶而分解。与 VIB 组的情况不同，在基质-IVB 组 TMC 的界面边界处没有形成过渡区。使用有关 TMC 电子结构和物理化学性质的数据讨论了实验结果。与 VIB 组的情况不同，在基质-IVB 组 TMC 的界面边界处没有形成过渡区。使用有关 TMC 电子结构和物理化学性质的数据讨论了实验结果。与 VIB 组的情况不同，在基质-IVB 组 TMC 的界面边界处没有形成过渡区。使用有关 TMC 电子结构和物理化学性质的数据讨论了实验结果。

Comparative Analysis of the Phase Interaction in Plasma Surfaced NiBSi Overlays with IVB and VIB Transition Metal Carbides

Important applications of transition metal carbides (TMCs) are as wear resistant composite layers deposited by plasma transferred arc welding (PTAW) and laser methods. Growing interest in them has also been observed in additive manufacturing and in HEA technology (bulk composite materials and layers), and in the area of energy conversion and storage. This paper presents the results of comparative studies on interfacial interactions in the NiBSi−TMCs system for two border IVB and VIB TM groups of the periodic table. Model (wettability and spreadability) and application experiments (testing of the PTAW-obtained carbide particle−matrix boundaries) were performed. Fe from partially melted steel substrates is active in the liquid NiBSi−TMCs system. It was revealed that the interaction of TMCs with the liquid NiBSi matrix tends to increase with the group number, and from the top to bottom inside individual groups. Particles of IVB TMCs are decomposed by penetration of the liquid along the grain boundaries, whereas those of VIB are decomposed by solubility in the matrix and secondary crystallization. No transition zones formed at the interfacial boundaries of the matrix−IVB group TMCs, unlike in the case of the VIB group. The experimental results are discussed using the data on the TMC electronic structure and the physicochemical properties.
