Abstract
In metal cutting, water-soluble cutting oil is used for cooling the surface of the workpiece and improving the surface roughness. However, waste cutting oil contains preservatives and surfactants, and if it is discarded as it is, it has an great influence on environmental pollution. For this reason, regulations on the use of cutting oil are being stricter. Hence, the development of eco-friendly treatment technologies is required. In this study, a diamond electrode doped with boron on a niobium substrate was deposited by thermal filament chemical vapor deposition and waste cutting oil was treated using an electrochemical method. Compared to the total amount of organic carbon contained in the waste cutting oil, it was confirmed that the boron-doped diamonds developed from this study showed much better performance than electrodes that has been widely used before.
