Investigation on the Effects of Nanoparticles on Cutting Fluid Properties and Tribological Characteristics

The application of cutting fluid is required to enable efficient machining processes. Depending on the process, additives are used to adjust the performance of the cutting fluid. This paper presents the strong influence of nanoparticles and microparticles on the cutting fluid properties as well as the tribological behavior. The effects of the particle size, the concentration and the base fluid were investigated for two different metal oxides, Al 2 O 3 and ZrO 2 , as well as silica. While most nanoparticles achieved an improved lubricity, the opposite was found for Al 2 O 3 .
