             abstract = "Although the 6150 steel has an excellent fatigue and impact 
                         resistance, it is unsuitable to operate it when the corrosion is a 
                         limited factor. We propose here a sequence of steel pre-treatment 
                         by carburizing, carbonitriding and nitriding in order to improve 
                         the poor adhesion between Diamond Like-Carbon coatings on steel. 
                         This sequence is our attempt to reduce the difference between the 
                         coefficients of thermal expansion of steel and DLC through the 
                         graded interface. This work demonstrates the quantitative analysis 
                         of the molecules present at surface using X-ray photoelectron 
                         spectroscopy. The crystallographic structures are investigated by 
                         X-ray diffraction which shows the formation of carbides and 
                         nitride phases. Raman spectroscopy reveals the carburizing surface 
                         characteristics where DLC coating is nucleated and grown at the 
                         substrate. At the end of the analysis it is possible to verify 
                         which molecules and phases are formed on the steel surface 
                         interface after each step of pre-treatment.",
