Composite multi-layer coatings for end mills

The results of theoretical and experimental studies of tribological characteristics of composite multilayer coatings for cutting tools for blade processing by milling are presented. Installed reducing the coefficient of friction, longer tool life and reduced thermal loading of the cutting zone in milling operations with the use of wear-resistant coatings.

An Insight into TiN, TiAlN and AlTiN Hard Coatings for Cutting Tools

The evolution of the metalworking industry over the centuries was greatly influenced by the development of a large range of cutting tools. Tool surface quality improvement with hard coatings generated considerable progress in the metal cutting industry. Hard coatings were composed mainly of nitrides, carbides, borides, and oxides of transition metals (typically Ti, Cr, Zr).1-5

Nanostructured Copper Coating Used as Textured Structure for cBN and TiN Hard Phase Deposition

In the case of cutting tools, the temperature of both the cutting tool and the part are decreased during the machining process by the use of cutting fluids, which are expensive, can be toxic and produce a significant waste stream. Coatings for cutting tools can be an effective approach to solve this problem. This paper will present a developed technology by a group of researchers from “Transilvania” University of Brașov, through which the copper`s surface will be nanostructurated at a nanometric scale in such a manner, for creating nodular structures. This technology is simple, easy for implementation, not so expensive and it`s results are proper for cutting tools coatings usage.
