Abstract

Possibility of nanosized carbon coatings synthesis on metal and dielectric surfaces at the result of carbon emission from different impurity amount graphite materials under millisecond pulses of Glass: Yb, Er laser. Size of particles and morphology of obtained coatings were investigated with scanning electron microscopy. It was found experimentally, that separated particles of obtained carbon coating has a size about 50-100 nm. Also Raman spectras of nanosized carbon coatings were obtained to investigate a structure. At the result of Raman spectras analysis was found, that coatings are contained of different structural units depends on graphite material impurity amount. For graphite material 99.9% products of laser evaporation are amorphous carbon nanoparticles, and for graphite material with impurity amount about 30% - graphitized nanoparticles. In this article mechanical properties, such as microhardness, of obtained coatings were estimated. It is shown that microhardness of metal surfaces and surface of substrates prepared from human tooth enamel and dentin could be increased significantly due to nanosized carbon coating. Also for tooth enamel and dentin substrates was observed an ability to increase its acid resistance and protective property of obtained coatings to the action of phosphic acid (37.5%).
