Investigation of the effect of nanosecond laser pulse processing on changes in the structural and phase composition and tribological properties of carbon diamond-like coatings
Raman spectroscopy (Raman method), optical metallography and scanning electron microscopy in combination with measuring tribological characteristics have been used to study the features of microrelief formation, changes in the structural-phase state during processing with nanosecond laser pulses, and the effect of such processing on the tribological characteristics of carbon coatings on the surface of 10H18N10T steel obtained by pulsed vacuum-arc sputtering, including subsequent laser irradiation with nanosecond pulses.
