PROPERTIES OF A TRIBOLOGICAL SYSTEM WITH A DIAMOND-LIKE CARBON COATING LUBRICATED WITH ENVIRONMENTALLY FRIENDLY CUTTING FLUID

This article presents experimental results obtained for an a-C:H:Si coating deposited on a 100Cr6 steel disc in sliding contact with a 100Cr6 steel ball in the presence of zinc aspartate-based cutting fluid. The study involved scanning electron microscopic examinations, contact angle measurements, tribological tests, and surface texture analysis. The experimental data suggest that the tribological properties of the diamond-like carbon (DLC) coating are satisfactory and that the non-toxic cutting fluid is well-suited to replace conventional fuels, which are toxic.
