Dry machining enhanced by superhard nanocomposites
Abstract:
For dry machining, high hardness and high oxidation-resistance are both important. That's why superhard nanocomposites, which represent a new, advanced generation of wear protective coatings boosting such advantages as high hardness and high oxidation, are important to dry machining, according to Professor Stan Veprek of the Department of Chemistry at the Technical University of Munich.
Speaking at the recently held 2007 International Conference & Exhibition on Nanotechnology and Advanced Materials, Professor Veprek referred superhard nanocomposites to those that consists of 3-4nm small nanocrystals of a hard transition metal nitride "glued" together by one monolayer of thin Si3N4 interfacial "tissue".
When correctly prepared and free of impurities, the superhard nc-TiN/a-Si3N4composites attain high hardness of at least 100 Gpa while featuring high elastic recover, high elastic limit, high resistance against brittle fracture, high thermal stability and oxidation resistance.
