THE TRIBOLOGICAL PROPERTIES OF COATINGS LUBRICATED WITH A BIODEGRADABLE CUTTING FLUID
Journal Title: Tribologia - Year 2015, Vol 263, Issue 5
Abstract
This paper presents the tribological results of on investigations of TiAlN coatings that were deposited on HS6-5-2C steel using the physical vapour deposition PVD technique. An observation of the coating structure was carried out using a scanning electron microscope SEM JSM - 7100F. Examinations of the geometric structures of the surface TiAlN coating before and after tribological tests were performed using an optical profilometer Talysurf CCI Lite. The tribological tests were performed using a T-01 M tester working in a ball-on-disk combination in sliding movement. Tests were carried out under friction with lubrication using cutting fluid containing improved additive-zinc aspartate. Studies have shown that the cutting fluid influenced the formation of anti-wear surface layers, which are secured against the direct contact of rubbing surfaces. This had the effect of reducing the resistance movement and, in addition, provided protection against corrosion during tests.<br/><br/>
