Ceramic cutting materials and tools suitable for machining high‐temperature nickel‐based alloys: A review

Abstract

Nickel‐based superalloys are attractive to many industrial sectors (automotive, military, energy, aerospace, etc.). However, their physical properties make them difficult to machining using traditional tools. Therefore, new materials for the machining of Ni‐based alloys are required. Ceramic‐based composites could act as a tool to replace the current materials. The incentives for this paper are to provide an overview of existing ceramic composites and draw some conclusions that will help in solving the problem of choosing materials for the processing of Ni‐based superalloys. Despite the diversity of ceramic composites in this work, the possibility of using the SiAlON ceramic for Ni‐based alloy machining is highlighted.
