Abstract

Three types of SiAlON ceramic tool materials (α-SiAlON, β-SiAlON, and α/β-SiAlON) were fabricated using hot-press sintering, and the correlations between mechanical properties and cutting performance through the machining of Inconel 718 were systematically investigated. The results showed that the α-SiAlON ceramic tool exhibited the highest hardness, resulting in reduced flank wear. However, its lowest indentation fracture resistance and flexural strength resulted in substantial tool tip wear. The β-SiAlON ceramic tool demonstrated the lowest hardness, resulting in excessive flank wear, while its moderate indentation fracture resistance and flexural strength contributed to moderate tool tip wear. The α/β-SiAlON ceramic tool exhibited moderate hardness, leading to acceptable flank wear, and the highest indentation fracture resistance and flexural strength, resulting in minimal tool tip wear. These results demonstrate that the dual-phase α/β design enables SiAlON ceramic tools to achieve optimal comprehensive performance in superalloy cutting applications.

α/β-SiAlON陶瓷刀具的力学性能和切削性能

采用热压烧结法制备了3种SiAlON陶瓷刀具材料（α-SiAlON、β-SiAlON和α/β-SiAlON），系统研究了加工Inconel 718的力学性能与切削性能之间的相关性。结果表明，α-SiAlON陶瓷刀具具有最高的硬度，减少了刀具侧面的磨损。然而，其最低的抗压痕断裂性和抗弯强度导致了大量的刀尖磨损。β-SiAlON陶瓷刀具的硬度最低，导致刀具侧面过度磨损，而其中等的抗压痕断裂能力和抗折强度导致刀具尖端磨损适中。α/β-SiAlON陶瓷刀具硬度适中，刃口磨损可接受，抗压痕断裂和抗折强度最高，刀尖磨损最小。这些结果表明，双相α/β设计使SiAlON陶瓷刀具在高温合金切削应用中获得最佳的综合性能。

期刊介绍： The International Journal of Refractory Metals and Hard Materials (IJRMHM) publishes original research articles concerned with all aspects of refractory metals and hard materials. Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than 1000 kg/mm2, primarily intended for applications as manufacturing tools or wear resistant components in mechanical systems. Thus they encompass carbides, nitrides and borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder. Ceramics and superhard materials including diamond and cubic boron nitride may also be accepted provided the subject material is presented as hard materials as defined above.
