摘要：

in this paper, comparative studies on mechanical properties and cutting performance between CrN and Cr-Si-N coatings for green micro end-milling were conducted. Ternary Cr-Si-N coatings, in which Si was incorporated into CrN, were synthesized onto WC-Co substrates using a hybrid system of arc ion plating and sputtering techniques. The high hardness of Cr-Si-N coatings was related to the composite microstructure consisting of the fine CrN crystallites and amorphous Si(3)N(4). The average friction coefficient of Cr-Si-N coatings gradually decreased with increase of Si content in CrN coatings. Cutting tests were carried out to evaluate the characteristics of micro cutting in vertical machining center using ultra-high speed air turbine spindle. An integrated evaluation system of cutting tools was introduced. Consequently, the Cr-Si(9.3 at.%)-N coated end-mill using semi-dry machining showed good cutting performance under ultra-high speed cutting condition. (c) 2008 Elsevier B.V. All rights reserved.
