Zirconium-based alloys are highly regarded by the research community for their exceptional corrosion resistance, thermal stability, and mechanical properties. In our work, we investigated two newly developed alloys, ZrCuAlAg and ZrCuAlAg, in the form of ingots and ribbons. In the course of our investigation, we conducted a comprehensive structural and thermal analysis. In addition, an examination of the corrosion activity encompassing electrochemical studies and an analysis of the corrosion mechanisms was carried out. To further evaluate the performance of the materials, tests of their mechanical properties were performed, including microhardness and resistance to abrasive wear. Structural analysis showed that both alloys studied had a multiphase, crystalline structure with intermetallic phases. The samples in the form of ribbons showed improved corrosion resistance compared to that of the ingots. The ingot containing a higher content of copper ZrCuAlAg was characterized by better corrosion resistance, while showing lower average hardness and a higher degree of abrasive wear based on SEM observations after pin-on-disc tests.
锆基合金因其出色的耐腐蚀性、热稳定性和机械性能而受到研究界的高度重视。在我们的工作中，我们研究了两种新开发的合金，铸锭和带材形式的ZrCuAlAg和ZrCuAlAg。在我们的研究过程中，我们进行了全面的结构和热分析。此外，还进行了包括电化学研究在内的腐蚀活性检查以及腐蚀机制分析。为了进一步评估材料的性能，对其机械性能进行了测试，包括显微硬度和耐磨性能。结构分析表明，所研究的两种合金均具有多相晶体结构和金属间相。与铸锭相比，带材形式的样品显示出更好的耐腐蚀性。基于销盘试验后的扫描电子显微镜观察，含铜量较高的ZrCuAlAg铸锭具有更好的耐腐蚀性，同时显示出较低的平均硬度和较高的磨料磨损程度。
