Abstract
Nickel-based alloys have excellent mechanical properties and are widely used in the aviation and aerospace industries. However, high-speed cutting of nickel-based alloys has the characteristics of high cutting force, high temperature, and low tool life. Tools with excellent performance are important for the high-quality machining of inner-base alloys in colleges and universities. Many scholars have begun to discuss the use of gradient functional materials and nanocomposite research methods to effectively integrate gradient functional thermal stress relaxation and surface compressive stress characteristics with nano-compliance toughening mechanisms to form Sialon-Si3N4 gradient nanocomposite ceramic tools. Based on this, this paper introduces the high-speed machining technology and its characteristics, establishes the corresponding model, and analyzes its cutting performance through experiments to clarify the application value of the Sialon-Si3N4 gradient nanocomposite ceramic tool.
