A Wear Sensor Based on Nanocrystalline Diamond Multilayer Films: A Mini Review

Abstract

Major amounts of industrial wear parts, e.g. machining tools, are working under extreme wear load, especially abrasive. This short article reviews the development and fabrication of a well-performing nanodiamond-based multilayer wear sensor system consisting of alternating conductive and non-conductive films. Meanwhile, the deposition and characterization of such highly conductive nanocrystalline diamond films without dopant are also introduced.
