Abstract

The paper considers multilayer composite nano-structured Ti-TiN-(Ti,Al,Cr,Si)N coatings for metal-cutting tools. The coatings under the study mechanical characteristics of the coatings were studied, and the tool life tests were carried out for carbide tools with the above coatings for dry about 80 nm). The turning of steel AISI 321(HB 180) at vc = 100, 150, and 200 m/min (f=0.11 mm/rev; ap=0.5 mm). Uncoated tools and tools with Ti-(Ti,Al)N coatings of traditional type were used as objects of comparison. The studies have found out that coatings with thinner nanolayers demonstrate better performance properties, especially at higher cutting speeds. © 2018 The Authors. Published by Elsevier Ltd.
