Abstract

In this work, the influence of refractory Zr and Ti and their combination (Zr,Ti) on the oxidation behavior of the (Hf,Ta,Nb)(C,N) carbonitride under non-isothermal and isothermal conditions at 1200 °C was studied, the effect of nitrogen addition was demonstrated, and a possible oxidation mechanisms were identified. The best result was achieved for high-entropy carbonitride (Hf,Ta,Nb,Zr,Ti)(C,N). The introduction of nitrogen into the of high-entropy carbide lattice contributed to a decrease in the specific weight gain by 12 %, and the addition of Ti, Zr, and (Zr,Ti) to the (Hf,Ta,Nb)(C,N) – a decrease of 47, 65, and 83 %, respectively.

具有优异抗氧化性的高熵碳氮化物：非等温和等温条件下氧化行为的制造和研究

在这项工作中，研究了难熔 Zr 和 Ti 及其组合 (Zr,Ti) 在 1200 °C 的非等温和等温条件下对 (Hf,Ta,Nb)(C,N) 碳氮化物氧化行为的影响，证明了氮添加的效果，并确定了可能的氧化机制。高熵碳氮化物 (Hf,Ta,Nb,Zr,Ti)(C,N)取得了最佳结果。在高熵碳化物晶格中引入氮元素可使比增重减少 12%，而在（Hf,Ta,Nb）(C,N)中加入 Ti、Zr 和 (Zr,Ti) 则可使比增重分别减少 47%、65% 和 83%。

期刊介绍： The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
