Abstract

The aim of the study was to determine the properties of a new non-toxic cutting fluid. This paper discusses results of the wear tests performed with a T-01 M tribometer for a ball-on-disk configuration in the sliding contact. The tests were carried out for steel disks with DLC/DLC Si coatings deposited by physical vapor deposition (PVD), which were in contact with 100Cr6 steel balls. The tests were conducted under dry friction conditions and under lubricated friction conditions with a cutting fluid containing zinc aspartate. The coating structure was examined using a Jeol JSM-7100F scanning electron microscope. The surface texture of the disks after the tribological tests was analyzed with a Talysurf CCI Lite optical measurement system. The cutting fluid used in the tests contributed to a reduction in the friction resistance and offered anti-corrosion protection.
