Investigating the Impact of Monolayer and Multilayer PVD Coatings on Cutting Tool Friction Factor
View through CrossRef
Abstract
The purpose of the paper is to examine the ZrSiN, monolayer TiN, and multilayer TiSiN PVD coatings' friction factors on tempered steel 45X (50 HRC) and steel 45 (180 HB). The tribological characteristics were studied using tribometer. The registered values of friction factor were transferred to the computer using an analog to digital converter. TiN coatings on both steel 45 (180 HB) and the tempered steel 45Х (50 HRC) shows an increase in friction factor. Friction factor of TiSiN coating at 70V and 150 V also increases with time. In case of ZrSiN, the friction factor remains constant for both the tool materials for deposition current of 150V.The results of the investigations provide useful information for applying ZrSiN PVD coating for the improvement of tool life of cutting tools. The paper contributes to better understanding of the friction properties of monolayer TiN, multilayer TiSiN, and ZrSiN PVD coatings deposited on steel 45 (180 HB) and the tempered steel 45Х (50 HRC).
