Investigation of the Surface-Modification Effect by Oil-Immersion Treatment on Carbide Tool

Abstract:

This paper describes the effect of oil-immersion treatment on the surfaces of cutting tools. In this study, the ‘oil-immersion treatment’ refers to the modification of the tool’s surface by immersing the tool in a treatment solution and heating under pressure. Our previous study demonstrated that such treatment reduces the wear on cutting tools. In this study, the effect of oil-immersion treatment on a carbide cutting tool was investigated by EPMA (electron probe microanalysis) and XPS (x-ray photoelectron spectroscopy). SEM (scanning electron microscope) and EPMA examination revealed that oil-immersion treatment reduces the amount of cobalt on the tool’s surface and forms sulphur deposits. XPS analysis of the chemical bonds on the surfaces revealed the presence of cobalt sulphide and inorganic carbon. In addition, friction tests showed that the oil-immersion treatment reduces the friction coefficient of the tool.
