Coated Carbide

The Inconel 718 superalloy is one of the most-used nickel based superalloys in the aerospace industry due to its superior mechanical properties, for instance, high thermal and chemical resistance, and high strength at elevated temperatures. However, the work hardening tendency, low thermal conductivity and high hardness of this superalloy cause early tool wear, leading to the material to be called as a hard-to-cut material. Therefore, deposition of a wear resistant hard coating on carbide cutting tools has a critical importance for longer tool life in milling operations of the Inconel 718 superalloy. In this study, carbide cutting tools were coated with multilayer nanocomposite TiAlSiN/TiSiN/TiAlN coating using the magnetron sputtering technique, and wear behavior of the coated tool was investigated during face milling of the Inconel 718 superalloy under dry conditions. Abrasive and adhesive wear mechanisms were founded as main failure mechanisms. The nanocomposite TiAlSiN/TiSiN/TiAlN coated carbide cutting tool gave better wear resistance, and thus it provided 1.7 times longer tool life and a smoother surface (Ra<0.18 μm) on the Inconel 718 material than the uncoated one.

Coated Carbide

A coated carbide cutting tool with its high hardness and high wear resistance, good chemical stability and extensive compatibility characteristics, is widely applied in the metal cutting processing field. It is one of the cutting tools, belonging to the current focus research and development project of all countries in the world. The author mainly studies the cutting force contrast between coated carbide cutting tools and not coated ones. At the same time study them on the rake face friction coefficient contrast and the chip deformation coefficient contrast so as to explain the reasons for coated cutting tool cutting force decrease. The research indicates that, in machining course, applying physical vapor deposition coated technology (PVD) of carbide cutting tools cutting force change with feeds, cutting depth and speed is the same as not coated carbide cutting tools. But coated carbide cutting tools cutting force is obviously less than that of not coated carbide cutting tools. The main reason is that the friction coefficient between the two kinds of cutting tool materials and the workpiece is different. The result of study will help popularization and application of coated carbide cutting tools.
