Abstract
In this paper, we present the results of fullerene film engraving using a diamond tool. Based on available literature data, to our knowledge the fullerene film machinability is not explored in literature. Therefore, we have investigated wear mechanisms of the engraving process that could be used in micromachining. The engraving process parameters were estimated on the basis of poor quality groove's edge. The flat diamond tip, which remains after wear, has a pitted surface which was observed with a digital optical microscopy and identified using AFM. Soot-like wear debris was observed and spectroscopically analyzed. FTIR spectroscopy results strongly indicate that fullerene C60 disappears as a molecule and interacts with oxygen, nitrogen and water vapor from the atmosphere. The occurrence of tool wear and wear debris were observed by nondestructive thermography testing. Results confirm that development of high temperature in a cutting zone of 1556°C causes extensive thermo-chemical tool wear.
