Abstract

In this study, the effect of the fraction of transformed carbon layer on the tribological properties has been investigated. The fraction of transformed carbon layer was controlled by varying the reaction temperature of the hydrogen. The degree of the transformed carbon layer was measured using energy dispersive X-ray (EDX), Raman spectroscopy, and X-ray diffraction (XRD) pattern. The mechanical properties of the trated layer were measured by using a micro-Vickers hardness tester. The frictional coefficient and wear rate of CDC layer were significantly lowered due to the formation of carbon layer. A severe to mild wear transition occurred, depending on the reaction temperature. The variation of fraction of the carbon was correlated with the tribological and mechanical properties.
